What it is for
Tadalafil is a phosphodiesterase 5 (PDE5) inhibitor indicated for the treatment of:
- erectile dysfunction (ED) ( 1.1 )
- the signs and symptoms of benign prostatic hyperplasia (BPH) ( 1.2 )
- ED and the signs and symptoms of BPH (ED/BPH) ( 1.3 ) If tadalafil tablet is used with finasteride to initiate BPH treatment, such use is recommended for up to 26 weeks ( 1.4 ). 1.1 Erectile Dysfunction Tadalafil tablet is indicated for the treatment of erectile dysfunction (ED). 1.2 Benign Prostatic Hyperplasia Tadalafil tablet is indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH). 1.3 Erectile Dysfunction and Benign Prostatic Hyperplasia Tadalafil tablet is indicated for the treatment of ED and the signs and symptoms of BPH (ED/BPH). 1.4 Limitation of Use If tadalafil tablet is used with finasteride to initiate BPH treatment, such use is recommended for up to 26 weeks because the incremental benefit of tadalafil tablets decreases from 4 weeks until 26 weeks, and the incremental benefit of tadalafil tablets beyond 26 weeks is unknown [see Clinical Studies ( 14.3 )].

How it works
From this product’s own US prescribing label.
Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and corpus cavernosal smooth muscle.
This response is mediated by the release of nitric oxide (NO) from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells.
Metabolism — Tadalafil is predominantly metabolized by CYP3A4 to a catechol metabolite.
Tadalafil is excreted predominantly as metabolites, mainly in the feces (approximately 61% of the dose) and to a lesser extent in the urine (approximately 36% of the dose).
The rate and extent of absorption of tadalafil are not influenced by food; thus tadalafil may be taken with or without food.

Do not take it if
- Administration of tadalafil tablets to patients using any form of organic nitrate is contraindicated. Tadalafil tablets was shown to potentiate the hypotensive effect of nitrates ( 4.1 ).
- History of known serious hypersensitivity reaction to tadalafil tablets or ADCIRCA ® ( 4.2 ).
- Administration with guanylate cyclase (GC) stimulators, such as riociguat ( 4.3 ). 4.1 Nitrates Administration of tadalafil tablets to patients who are using any form of organic nitrate, either regularly and/or intermittently, is contraindicated. In clinical pharmacology studies, tadalafil tablets was shown to potentiate the hypotensive effect of nitrates [see Clinical Pharmacology ( 12.2 )]. 4.2 Hypersensitivity Reactions Tadalafil tablet is contraindicated in patients with a known serious hypersensitivity to tadalafil (tadalafil tablets or ADCIRCA ® ). Hypersensitivity reactions have been reported, including Stevens-Johnson syndrome and exfoliative dermatitis [see Adverse Reactions ( 6.2 )]. 4.3 Concomitant Guanylate Cyclase (GC) Stimulators
- Do not use tadalafil tablets in patients who are using a GC stimulator, such as riociguat. PDE5 inhibitors, including tadalafil tablets, may potentiate the hypotensive effects of GC stimulators.

Other warnings
- Patients should not use tadalafil if sex is inadvisable due to cardiovascular status ( 5.1 ).
- Use of tadalafil with alpha-blockers, antihypertensives or substantial amounts of alcohol (≥5 units) may lead to hypotension ( 5.6 , 5.9 ).
- Tadalafil is not recommended in combination with alpha-blockers for the treatment of BPH because efficacy of the combination has not been adequately studied and because of the risk of blood pressure lowering. Caution is advised when tadalafil tablet is used as a treatment for ED in men taking alpha-blockers. ( 2.7 , 5.6 , 7.1 , 12.2 )
- Patients should seek emergency treatment if an erection lasts >4 hours. Use tadalafil with caution in patients predisposed to priapism ( 5.3 ).
- Patients should stop tadalafil and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of non-arteritic anterior ischemic optic neuropathy (NAION). Tadalafil tablets should be used with caution, and only when the anticipated benefits outweigh the risks, in patients with a history of NAION. Patients with a "crowded" optic disc may also be at an increased risk of NAION ( 5.4 , 6.2 ).
- Patients should stop tadalafil and seek prompt medical attention in the event of sudden decrease or loss of hearing ( 5.5 ).
- Prior to initiating treatment with tadalafil tablets for BPH, consideration should be given to other urological conditions that may cause similar symptoms ( 5.14 ). 5.1 Cardiovascular Evaluation of erectile dysfunction and BPH should include an appropriate medical assessment to identify potential underlying causes, as well as treatment options. Before prescribing tadalafil, it is important to note the following:
- Physicians should consider the cardiovascular status of their patients, since there is a degree of cardiac risk associated with sexual activity. Therefore, treatments for erectile dysfunction, including tadalafil, should not be used in men for whom sexual activity is inadvisable as a result of their underlying cardiovascular status. Patients who experience symptoms upon initiation of sexual activity should be advised to refrain from further sexual activity and seek immediate medical attention. Physicians should discuss with patients the appropriate action in the event that they experience anginal chest pain requiring nitroglycerin following intake of tadalafil. In such a patient, who has taken tadalafil, where nitrate administration is deemed medically necessary for a life-threatening situation, at least 48 hours should have elapsed after the last dose of tadalafil before nitrate administration is considered. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring. Therefore, patients who experience anginal chest pain after taking tadalafil should seek immediate medical attention [see Contraindications ( 4.1 ) and Patient Counseling Information ( 17.1 )]. Patients with left ventricular outflow obstruction, (e.g., aortic stenosis and idiopathic hypertrophic subaortic stenosis) can be sensitive to the action of vasodilators, including PDE5 inhibitors. The following groups of patients with cardiovascular disease were not included in clinical safety and efficacy trials for tadalafil, and therefore until further information is available, tadalafil is not recommended for the following groups of patients:
- myocardial infarction within the last 90 days
- unstable angina or angina occurring during sexual intercourse
- New York Heart Association Class 2 or greater heart failure in the last 6 months
- uncontrolled arrhythmias, hypotension (<90/50 mm Hg), or uncontrolled hypertension
- stroke within the last 6 months. As with other PDE5 inhibitors, tadalafil has mild systemic vasodilatory properties that may result in transient decreases in blood pressure. In a clinical pharmacology study, tadalafil 20 mg resulted in a mean maximal decrease in supine blood pressure, relative to placebo, of 1.6/0.8 mm Hg in healthy subjects [see Clinical Pharmacology ( 12.2 )]. While this effect should not be of consequence in most patients, prior to prescribing tadalafil, physicians should carefully consider whether their patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects. Patients with severely impaired autonomic control of blood pressure may be particularly sensitive to the actions of vasodilators, including PDE5 inhibitors. 5.2 Potential for Drug Interactions When Taking Tadalafil for Once Daily Use Physicians should be aware that tadalafil for once daily use provides continuous plasma tadalafil levels and should consider this when evaluating the potential for interactions with medications (e.g., nitrates, alpha-blockers, anti-hypertensives and potent inhibitors of CYP3A4) and with substantial consumption of alcohol [see Drug Interactions ( 7.1 , 7.2 , 7.3 )]. 5.3 Prolonged Erection There have been rare reports of prolonged erections greater than 4 hours and priapism (painful erections greater than 6 hours in duration) for this class of compounds. Priapism, if not treated promptly, can result in irreversible damage to the erectile tissue. Patients who have an erection lasting greater than 4 hours, whether painful or not, should seek emergency medical attention. Tadalafil should be used with caution in patients who have conditions that might predispose them to priapism (such as sickle cell anemia, multiple myeloma, or leukemia), or in patients with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease). 5.4 Effects on the Eye Physicians should advise patients to
- stop use of all phosphodiesterase type 5 (PDE5) inhibitors, including tadalafil, and seek medical attention in the event of a sudden loss of vision in one or both eyes. Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition and a cause of decreased vision, including permanent loss of vision, that has been reported rarely postmarketing in temporal association with the use of all PDE5 inhibitors. Based on published literature, the annual incidence of NAION is 2.5 to 11.8 cases per 100,000 in males aged ≥50. An observational case-crossover study evaluated the risk of NAION when PDE5 inhibitor use, as a class, occurred immediately before NAION onset (within 5 half-lives), compared to PDE5 inhibitor use in a prior time period. The results suggest an approximate 2-fold increase in the risk of NAION, with a risk estimate of 2.15 (95% CI 1.06, 4.34). A similar study reported a consistent result, with a risk estimate of 2.27 (95% CI 0.99, 5.20). Other risk factors for NAION, such as the presence of "crowded" optic disc, may have contributed to the occurrence of NAION in these studies. Neither the rare postmarketing reports, nor the association of PDE5 inhibitor use and NAION in the observational studies, substantiate a causal relationship between PDE5 inhibitor use and NAION [see Adverse Reactions ( 6.2 )]. Physicians should consider whether their patients with underlying NAION risk factors could be adversely affected by use of PDE5 inhibitors. Individuals who have already experienced NAION are at increased risk of NAION recurrence. Therefore, PDE5 inhibitors, including tadalafil, should be used with caution in these patients and only when the anticipated benefits outweigh the risks. Individuals with "crowded" optic disc are also considered at greater risk for NAION compared to the general population; however, evidence is insufficient to support screening of prospective users of PDE5 inhibitors, including tadalafil, for this uncommon condition. Patients with known hereditary degenerative retinal disorders, including retinitis pigmentosa, were not included in the clinical trials, and use in these patients is not recommended. 5.5 Sudden Hearing Loss Physicians should advise patients to stop taking PDE5 inhibitors, including tadalafil, and seek prompt medical attention in the event of sudden decrease or loss of hearing. These events, which may be accompanied by tinnitus and dizziness, have been reported in temporal association to the intake of PDE5 inhibitors, including tadalafil. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors [see Adverse Reactions ( 6.1 , 6.2 )]. 5.6 Alpha-blockers and Antihypertensives Physicians should discuss with patients the potential for tadalafil to augment the blood-pressure-lowering effect of alpha-blockers and antihypertensive medications [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.2 )]. Caution is advised when PDE5 inhibitors are coadministered with alpha-blockers. PDE5 inhibitors, including tadalafil, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. In some patients, concomitant use of these two drug classes can lower blood pressure significantly [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.2 )], which may lead to symptomatic hypotension (e.g., fainting). Consideration should be given to the following:
- ED
- Patients should be stable on alpha-blocker therapy prior to initiating a PDE5 inhibitor. Patients who demonstrate hemodynamic instability on alpha-blocker therapy alone are at increased risk of symptomatic hypotension with concomitant use of PDE5 inhibitors.
- In those patients who are stable on alpha-blocker therapy, PDE5 inhibitors should be initiated at the lowest recommended dose.
- In those patients already taking an optimized dose of PDE5 inhibitor, alpha-blocker therapy should be initiated at the lowest dose. Stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure when taking a PDE5 inhibitor.
- Safety of combined use of PDE5 inhibitors and alpha-blockers may be affected by other variables, including intravascular volume depletion and other antihypertensive drugs. [see Dosage and Administration ( 2.7 ) and Drug Interactions ( 7.1 )]. BPH
- The efficacy of the coadministration of an alpha-blocker and tadalafil for the treatment of BPH has not been adequately studied, and due to the potential vasodilatory effects of combined use resulting in blood pressure lowering, the combination of tadalafil and alpha-blockers is not recommended for the treatment of BPH. [see Dosage and Administration ( 2.7 ), Drug Interactions ( 7.1 ), and Clinical Pharmacology ( 12.2. )].
- Patients on alpha-blocker therapy for BPH should discontinue their alpha-blocker at least one day prior to starting tadalafil for once daily use for the treatment of BPH. 5.7 Renal Impairment Tadalafil for Use as Needed Tadalafil should be limited to 5 mg not more than once in every 72 hours in patients with creatinine clearance less than 30 mL/min or end-stage renal disease on hemodialysis. The starting dose of tadalafil in patients with creatinine clearance 30 to 50 mL/min should be 5 mg not more than once per day, and the maximum dose should be limited to 10 mg not more than once in every 48 hours [see Use in Specific Populations ( 8.7 )]. Tadalafil for Once Daily Use ED Due to increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis, tadalafil for once daily use is not recommended in patients with creatinine clearance less than 30 mL/min [see Use in Specific Populations ( 8.7 )]. BPH and ED/BPH Due to increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis, tadalafil for once daily use is not recommended in patients with creatinine clearance less than 30 mL/min. In patients with creatinine clearance 30 to 50 mL/min, start dosing at 2.5 mg once daily, and increase the dose to 5 mg once daily based upon individual response [see Dosage and Administration ( 2.6 ), Use in Specific Populations ( 8.7 ), and Clinical Pharmacology ( 12.3 )]. 5.8 Hepatic Impairment Tadalafil for Use as Needed In patients with mild or moderate hepatic impairment, the dose of tadalafil should not exceed 10 mg. Because of insufficient information in patients with severe hepatic impairment, use of tadalafil in this group is not recommended [see Use in Specific Populations ( 8.6 )]. Tadalafil for Once Daily Use Tadalafil for once daily use has not been extensively evaluated in patients with mild or moderate hepatic impairment. Therefore, caution is advised if tadalafil tablets for once daily use is prescribed to these patients. Because of insufficient information in patients with severe hepatic impairment, use of tadalafil in this group is not recommended [see Use in Specific Populations ( 8.6 )]. 5.9 Alcohol Patients should be made aware that both alcohol and tadalafil, a PDE5 inhibitor, act as mild vasodilators. When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased. Therefore, physicians should inform patients that substantial consumption of alcohol (e.g., 5 units or greater) in combination with tadalafil can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache [see Clinical Pharmacology ( 12.2 )]. 5.10 Concomitant Use of Potent Inhibitors of Cytochrome P450 3A4 (CYP3A4) Tadalafil is metabolized predominantly by CYP3A4 in the liver. The dose of tadalafil for use as needed should be limited to 10 mg no more than once every 72 hours in patients taking potent inhibitors of CYP3A4 such as ritonavir, ketoconazole, and itraconazole [see Drug Interactions ( 7.2 )]. In patients taking potent inhibitors of CYP3A4 and tadalafil for once daily use, the maximum recommended dose is 2.5 mg [see Dosage and Administration ( 2.7 )]. 5.11 Combination With Other PDE5 Inhibitors or Erectile Dysfunction Therapies The safety and efficacy of combinations of tadalafil and other PDE5 inhibitors or treatments for erectile dysfunction have not been studied. Inform patients not to take tadalafil with other PDE5 inhibitors, including ADCIRCA. 5.12 Effects on Bleeding Studies in vitro have demonstrated that tadalafil is a selective inhibitor of PDE5. PDE5 is found in platelets. When administered in combination with aspirin, tadalafil 20 mg did not prolong bleeding time, relative to aspirin alone. Tadalafil has not been administered to patients with bleeding disorders or significant active peptic ulceration. Although tadalafil has not been shown to increase bleeding times in healthy subjects, use in patients with bleeding disorders or significant active peptic ulceration should be based upon a careful risk-benefit assessment and caution. 5.13 Counseling Patients About Sexually Transmitted Diseases The use of tadalafil offers no protection against sexually transmitted diseases. Counseling patients about the protective measures necessary to guard against sexually transmitted diseases, including Human Immunodeficiency Virus (HIV) should be considered. 5.14 Consideration of Other Urological Conditions Prior to Initiating Treatment for BPH Prior to initiating treatment with tadalafil for BPH, consideration should be given to other urological conditions that may cause similar symptoms. In addition, prostate cancer and BPH may coexist.

Pregnancy and breastfeeding
- Risk Summary Tadalafil is not indicated for use in females.
- There are no data with the use of tadalafil in pregnant women to inform any drug-associated risks for adverse developmental outcomes.
- In animal reproduction studies, no adverse developmental effects were observed with oral administration of tadalafil to pregnant rats or mice during organogenesis at exposures up to 11 times the maximum recommended human dose (MRHD) of 20 mg/day ( see Data).
- Data Animal Data Animal reproduction studies showed no evidence of teratogenicity, embryotoxicity, or fetotoxicity when tadalafil was given orally to pregnant rats or mice at exposures up to 11 times the maximum recommended human dose (MRHD) of 20 mg/day during organogenesis.
- In a prenatal/postnatal developmental study in rats, postnatal pup survival decreased following maternal exposure to tadalafil doses greater than 10 times the MRHD based on AUC.
- Signs of maternal toxicity occurred at doses greater than 16 times the MRHD based on AUC.
- Surviving offspring had normal development and reproductive performance.
- In another rat prenatal and postnatal development study at doses of 60, 200, and 1,000 mg/kg, a reduction in postnatal survival of pups was observed.
- The no observed effect level (NOEL) for maternal toxicity was 200 mg/kg/day and for developmental toxicity was 30 mg/kg/day.
- This gives approximately 16 and 10 fold exposure multiples, respectively, of the human AUC for the MRHD of 20 mg.
- Tadalafil and/or its metabolites cross the placenta, resulting in fetal exposure in rats.
- IN SPECIFIC POPULATIONS Hepatic Impairment ( 2.6 , 5.8 , 8.6 ):
- Mild or Moderate: Dosage adjustment may be needed.
- Severe: Use is not recommended. Renal Impairment ( 2.6 , 5.7 , 8.7 ):
- Patients with creatinine clearance 30 to 50 mL/min: Dosage adjustment may be needed.
- Patients with creatinine clearance less than 30 mL/min or on hemodialysis:
- For use as needed:
- Dose should not exceed 5 mg every 72 hours. Once daily use is not recommended. 8.1 Pregnancy Risk Summary Tadalafil is not indicated for use in females. There are no data with the use of tadalafil in pregnant women to inform any drug-associated risks for adverse developmental outcomes. In animal reproduction studies, no adverse developmental effects were observed with oral administration of tadalafil to pregnant rats or mice during organogenesis at exposures up to 11 times the maximum recommended human dose (MRHD) of 20 mg/day ( see Data). Data Animal Data Animal reproduction studies showed no evidence of teratogenicity, embryotoxicity, or fetotoxicity when tadalafil was given orally to pregnant rats or mice at exposures up to 11 times the maximum recommended human dose (MRHD) of 20 mg/day during organogenesis. In a prenatal/postnatal developmental study in rats, postnatal pup survival decreased following maternal exposure to tadalafil doses greater than 10 times the MRHD based on AUC. Signs of maternal toxicity occurred at doses greater than 16 times the MRHD based on AUC. Surviving offspring had normal development and reproductive performance. In another rat prenatal and postnatal development study at doses of 60, 200, and 1,000 mg/kg, a reduction in postnatal survival of pups was observed. The no observed effect level (NOEL) for maternal toxicity was 200 mg/kg/day and for developmental toxicity was 30 mg/kg/day. This gives approximately 16 and 10 fold exposure multiples, respectively, of the human AUC for the MRHD of 20 mg. Tadalafil and/or its metabolites cross the placenta, resulting in fetal exposure in rats. 8.2 Lactation Risk Summary Tadalafil is not indicated for use in females. There is no information on the presence of tadalafil and/or metabolites in human milk, the effects on the breastfed child, or the effects on milk production. Tadalafil and/or its metabolites are present in the milk of lactating rats at concentrations approximately 2.4-fold greater than found in the plasma. 8.3 Females and Males of Reproductive Potential Infertility Based on the data from 3 studies in adult males, tadalafil decreased sperm concentrations in the study of 10 mg tadalafil for 6 months and the study of 20 mg tadalafil for 9 months. This effect was not seen in the study of 20 mg tadalafil taken for 6 months. There was no adverse effect of tadalafil 10 mg or 20 mg on mean concentrations of testosterone, luteinizing hormone or follicle stimulating hormone. The clinical significance of the decreased sperm concentrations in the two studies is unknown. There have been no studies evaluating the effect of tadalafil on fertility in men [see Clinical Pharmacology ( 12.2 )]. Based on studies in animals, a decrease in spermatogenesis was observed in dogs, but not in rats [see Nonclinical Toxicology ( 13.1 )]. 8.4 Pediatric Use Tadalafil is not indicated for use in pediatric patients. Safety and efficacy in patients below the age of 18 years have not been established. Juvenile Animal Study No adverse effects were observed in a study in which tadalafil was administered orally at doses of 60, 200, and 1,000 mg/kg/day to juvenile rats on postnatal days 14 to 90. The highest plasma tadalafil exposures (AUC) achieved were approximately 10-fold that observed at the MRHD. Additional information describing a clinical study in which efficacy was not demonstrated is approved for Eli Lilly and Company's CIALIS (tadalafil) tablets. However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information. 8.5 Geriatric Use Of the total number of subjects in ED clinical studies of tadalafil, approximately 19 percent were 65 and over, while approximately 2 percent were 75 and over. Of the total number of subjects in BPH clinical studies of tadalafil (including the ED/BPH study), approximately 40 percent were over 65, while approximately 10 percent were 75 and over. In these clinical trials, no overall differences in efficacy or safety were observed between older (>65 and ≥75 years of age) and younger subjects (≤65 years of age). However, in placebo-controlled studies with tadalafil for use as needed for ED, diarrhea was reported more frequently in patients 65 years of age and older who were treated with tadalafil (2.5% of patients) [see Adverse Reactions ( 6.1 )]. No dose adjustment is warranted based on age alone. However, a greater sensitivity to medications in some older individuals should be considered [see Clinical Pharmacology ( 12.3 )]. 8.6 Hepatic Impairment In clinical pharmacology studies, tadalafil exposure (AUC) in subjects with mild or moderate hepatic impairment (Child-Pugh Class A or B) was comparable to exposure in healthy subjects when a dose of 10 mg was administered. There are no available data for doses higher than 10 mg of tadalafil in patients with hepatic impairment. Insufficient data are available for subjects with severe hepatic impairment (Child-Pugh Class C) [see Dosage and Administration ( 2.6 ) and Warnings and Precautions ( 5.8 )]. 8.7 Renal Impairment In clinical pharmacology studies using single-dose tadalafil (5 to 10 mg), tadalafil exposure (AUC) doubled in subjects with creatinine clearance 30 to 80 mL/min. In subjects with end-stage renal disease on hemodialysis, there was a two-fold increase in C max and 2.7- to 4.8-fold increase in AUC following single-dose administration of 10 or 20 mg tadalafil. Exposure to total methylcatechol (unconjugated plus glucuronide) was 2- to 4-fold higher in subjects with renal impairment, compared to those with normal renal function. Hemodialysis (performed between 24 and 30 hours post-dose) contributed negligibly to tadalafil or metabolite elimination. In a clinical pharmacology study (N=28) at a dose of 10 mg, back pain was reported as a limiting adverse event in male patients with creatinine clearance 30 to 50 mL/min. At a dose of 5 mg, the incidence and severity of back pain was not significantly different than in the general population. In patients on hemodialysis taking 10 or 20 mg tadalafil, there were no reported cases of back pain [see Dosage and Administration ( 2.6 ) and Warnings and Precautions ( 5.7 )].

Other medicines
- Tadalafil can potentiate the hypotensive effects of nitrates, alpha-blockers, antihypertensives or alcohol ( 7.1 ).
- CYP3A4 inhibitors (e.g. ketoconazole, ritonavir) increase tadalafil exposure ( 2.7 , 5.10 , 7.2 ) requiring dose adjustment:
- Tadalafil for use as needed: no more than 10 mg every 72 hours
- Tadalafil for once daily use: dose not to exceed 2.5 mg
- CYP3A4 inducers (e.g. rifampin) decrease tadalafil exposure ( 7.2 ). 7.1 Potential for Pharmacodynamic Interactions with Tadalafil Nitrates — Administration of tadalafil to patients who are using any form of organic nitrate, is contraindicated. In clinical pharmacology studies, tadalafil was shown to potentiate the hypotensive effect of nitrates. In a patient who has taken tadalafil, where nitrate administration is deemed medically necessary in a life-threatening situation, at least 48 hours should elapse after the last dose of tadalafil before nitrate administration is considered. In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring [see Dosage and Administration ( 2.7 ), Contraindications ( 4.1 ), and Clinical Pharmacology ( 12.2 )]. Alpha-Blockers — Caution is advised when PDE5 inhibitors are coadministered with alpha-blockers. PDE5 inhibitors, including tadalafil, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. Clinical pharmacology studies have been conducted with coadministration of tadalafil with doxazosin, tamsulosin or alfuzosin [see Dosage and Administration ( 2.7 ), Warnings and Precautions ( 5.6 ), and Clinical Pharmacology ( 12.2 )]. Antihypertensives — PDE5 inhibitors, including tadalafil, are mild systemic vasodilators. Clinical pharmacology studies were conducted to assess the effect of tadalafil on the potentiation of the blood-pressure-lowering effects of selected antihypertensive medications (amlodipine, angiotensin II receptor blockers, bendrofluazide, enalapril, and metoprolol). Small reductions in blood pressure occurred following coadministration of tadalafil with these agents compared with placebo [see Warnings and Precautions ( 5.6 ) and Clinical Pharmacology ( 12.2 )]. Alcohol — Both alcohol and tadalafil, a PDE5 inhibitor, act as mild vasodilators. When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased. Substantial consumption of alcohol (e.g., 5 units or greater) in combination with tadalafil can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache. Tadalafil did not affect alcohol plasma concentrations and alcohol did not affect tadalafil plasma concentrations [see Warnings and Precautions ( 5.9 ) and Clinical Pharmacology ( 12.2 )]. 7.2 Potential for Other Drugs to Affect Tadalafil [See Dosage and Administration ( 2.7 ) and Warnings and Precautions ( 5.10 )]. Antacids — Simultaneous administration of an antacid (magnesium hydroxide/aluminum hydroxide) and tadalafil reduced the apparent rate of absorption of tadalafil without altering exposure (AUC) to tadalafil. H 2 Antagonists (e.g. Nizatidine) — An increase in gastric pH resulting from administration of nizatidine had no significant effect on pharmacokinetics. Cytochrome P450 Inhibitors — Tadalafil is a substrate of and predominantly metabolized by CYP3A4. Studies have shown that drugs that inhibit CYP3A4 can increase tadalafil exposure. CYP3A4 (e.g., Ketoconazole) — Ketoconazole (400 mg daily), a selective and potent inhibitor of CYP3A4, increased tadalafil 20 mg single-dose exposure (AUC) by 312% and C max by 22%, relative to the values for tadalafil 20 mg alone. Ketoconazole (200 mg daily) increased tadalafil 10 mg single-dose exposure (AUC) by 107% and C max by 15%, relative to the values for tadalafil 10 mg alone [see Dosage and Administration ( 2.7 )]. Although specific interactions have not been studied, other CYP3A4 inhibitors, such as erythromycin, itraconazole, and grapefruit juice, would likely increase tadalafil exposure. HIV Protease inhibitor — Ritonavir (500 mg or 600 mg twice daily at steady state), an inhibitor of CYP3A4, CYP2C9, CYP2C19, and CYP2D6, increased tadalafil 20 mg single-dose exposure (AUC) by 32% with a 30% reduction in C max , relative to the values for tadalafil 20 mg alone. Ritonavir (200 mg twice daily), increased tadalafil 20 mg single-dose exposure (AUC) by 124% with no change in C max , relative to the values for tadalafil 20 mg alone. Although specific interactions have not been studied, other HIV protease inhibitors would likely increase tadalafil exposure [see Dosage and Administration ( 2.7 )]. Cytochrome P450 Inducers — Studies have shown that drugs that induce CYP3A4 can decrease tadalafil exposure. CYP3A4 (e.g., Rifampin) — Rifampin (600 mg daily), a CYP3A4 inducer, reduced tadalafil 10 mg single-dose exposure (AUC) by 88% and C max by 46%, relative to the values for tadalafil 10 mg alone. Although specific interactions have not been studied, other CYP3A4 inducers, such as carbamazepine, phenytoin, and phenobarbital, would likely decrease tadalafil exposure. No dose adjustment is warranted. The reduced exposure of tadalafil with the coadministration of rifampin or other CYP3A4 inducers can be anticipated to decrease the efficacy of tadalafil for once daily use; the magnitude of decreased efficacy is unknown. 7.3 Potential for Tadalafil to Affect Other Drugs Aspirin — Tadalafil did not potentiate the increase in bleeding time caused by aspirin. Cytochrome P450 Substrates — Tadalafil is not expected to cause clinically significant inhibition or induction of the clearance of drugs metabolized by cytochrome P450 (CYP) isoforms. Studies have shown that tadalafil does not inhibit or induce P450 isoforms CYP1A2, CYP3A4, CYP2C9, CYP2C19, CYP2D6, and CYP2E1. CYP1A2 (e.g. Theophylline) — Tadalafil had no significant effect on the pharmacokinetics of theophylline. When tadalafil was administered to subjects taking theophylline, a small augmentation (3 beats per minute) of the increase in heart rate associated with theophylline was observed. CYP2C9 (e.g. Warfarin) — Tadalafil had no significant effect on exposure (AUC) to S-warfarin or R-warfarin, nor did tadalafil affect changes in prothrombin time induced by warfarin. CYP3A4 (e.g. Midazolam or Lovastatin) — Tadalafil had no significant effect on exposure (AUC) to midazolam or lovastatin. P-glycoprotein (e.g. Digoxin) — Coadministration of tadalafil (40 mg once per day) for 10 days did not have a significant effect on the steady-state pharmacokinetics of digoxin (0.25 mg/day) in healthy subjects.

If you take too much
In an emergency, call your local emergency number or a poison control centre.
- Single doses up to 500 mg have been given to healthy subjects, and multiple daily doses up to 100 mg have been given to patients.
- Adverse events were similar to those seen at lower doses.
- In cases of overdose, standard supportive measures should be adopted as required.
- Hemodialysis contributes negligibly to tadalafil elimination.
Quoted from the official label, section “Overdosage”.
Use in children
- Tadalafil is not indicated for use in pediatric patients.
- Safety and efficacy in patients below the age of 18 years have not been established.
- Juvenile Animal Study No adverse effects were observed in a study in which tadalafil was administered orally at doses of 60, 200, and 1,000 mg/kg/day to juvenile rats on postnatal days 14 to 90.
- The highest plasma tadalafil exposures (AUC) achieved were approximately 10-fold that observed at the MRHD.
- Additional information describing a clinical study in which efficacy was not demonstrated is approved for Eli Lilly and Company's CIALIS (tadalafil) tablets.
- However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information.
Quoted from the official label, section “Pediatric Use”.
Use in older people
- Of the total number of subjects in ED clinical studies of tadalafil, approximately 19 percent were 65 and over, while approximately 2 percent were 75 and over.
- Of the total number of subjects in BPH clinical studies of tadalafil (including the ED/BPH study), approximately 40 percent were over 65, while approximately 10 percent were 75 and over.
- In these clinical trials, no overall differences in efficacy or safety were observed between older (>65 and ≥75 years of age) and younger subjects (≤65 years of age).
- However, in placebo-controlled studies with tadalafil for use as needed for ED, diarrhea was reported more frequently in patients 65 years of age and older who were treated with tadalafil (2.5% of patients) [see Adverse Reactions ( 6.1 )].
- No dose adjustment is warranted based on age alone.
- However, a greater sensitivity to medications in some older individuals should be considered [see Clinical Pharmacology ( 12.3 )].

- 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
- Tadalafil was administered to over 9,000 men during clinical trials worldwide.
- In trials of tadalafil for once daily use, a total of 1,434, 905, and 115 were treated for at least 6 months, 1 year, and 2 years, respectively.
- For tadalafil for use as needed, over 1,300 and 1,000 subjects were treated for at least 6 months and 1 year, respectively.
- Tadalafil for Use as Needed for ED In eight primary placebo-controlled clinical studies of 12 weeks duration, mean age was 59 years (range 22 to 88) and the discontinuation rate due to adverse events in patients treated with tadalafil 10 or 20 mg was 3.1%, compared to 1.4% in placebo treated patients.
- When taken as recommended in the placebo-controlled clinical trials, the following adverse reactions were reported ( see Table 1) for tadalafil for use as needed:

- gastroesophageal reflux disease, upper abdominal pain, nausea, vomiting, arthralgia, and muscle spasm.
- Back pain or myalgia was reported at incidence rates described in Tables 1 through 4.
- In tadalafil clinical pharmacology trials, back pain or myalgia generally occurred 12 to 24 hours after dosing and typically resolved within 48 hours.
- The back pain/myalgia associated with tadalafil treatment was characterized by diffuse bilateral lower lumbar, gluteal, thigh, or thoracolumbar muscular discomfort and was exacerbated by recumbency.
- In general, pain was reported as mild or moderate in severity and resolved without medical treatment, but severe back pain was reported with a low frequency (<5% of all reports).
- When medical treatment was necessary, acetaminophen or non-steroidal anti-inflammatory drugs were generally effective; however, in a small percentage of subjects who required treatment, a mild narcotic (e.g., codeine) was used.
- Overall, approximately 0.5% of all subjects treated with tadalafil for on demand use discontinued treatment as a consequence of back pain/myalgia.
- In the 1-year open label extension study, back pain and myalgia were reported in 5.5% and 1.3% of patients, respectively.
- Diagnostic testing, including measures for inflammation, muscle injury, or renal damage revealed no evidence of medically significant underlying pathology.
- Incidence rates for tadalafil for once daily use for ED, BPH and BPH/ED are described in Tables 2, 3 and 4.
- In studies of tadalafil for once daily use, adverse reactions of back pain and myalgia were generally mild or moderate with a discontinuation rate of <1% across all indications.
- Across placebo-controlled studies with tadalafil for use as needed for ED, diarrhea was reported more frequently in patients 65 years of age and older who were treated with tadalafil (2.5% of patients) [see Use in Specific Populations ( 8.5 )].
- Across all studies with any tadalafil dose, reports of changes in color vision were rare (<0.1% of patients).
- The following section identifies additional, less frequent events (<2%) reported in controlled clinical trials of tadalafil for once daily use or use as needed.
- A causal relationship of these events to tadalafil is uncertain.
- Excluded from this list are those events that were minor, those with no plausible relation to drug use, and reports too imprecise to be meaningful:
- Body as a Whole — asthenia, face edema, fatigue, pain, peripheral edema Cardiovascular — angina pectoris, chest pain, hypotension, myocardial infarction, postural hypotension, palpitations, syncope, tachycardia Digestive — abnormal liver function tests, dry mouth, dysphagia, esophagitis, gastritis, GGTP increased, loose stools, nausea, upper abdominal pain, vomiting, gastroesophageal reflux disease, hemorrhoidal hemorrhage, rectal hemorrhage Musculoskeletal — arthralgia, neck pain Nervous — dizziness, hypesthesia, insomnia, paresthesia, somnolence, vertigo Renal and Urinary — renal impairment Respiratory — dyspnea, epistaxis, pharyngitis Skin and Appendages — pruritus, rash, sweating Ophthalmologic — blurred vision, changes in color vision, conjunctivitis (including conjunctival hyperemia), eye pain, lacrimation increase, swelling of eyelids Otologic — sudden decrease or loss of hearing, tinnitus Urogenital — erection increased, spontaneous penile erection
- 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of tadalafil.
- Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
- These events have been chosen for inclusion either due to their seriousness, reporting frequency, lack of clear alternative causation, or a combination of these factors.
- Cardiovascular and Cerebrovascular — Serious cardiovascular events, including myocardial infarction, sudden cardiac death, stroke, chest pain, palpitations, and tachycardia, have been reported postmarketing in temporal association with the use of tadalafil.
- Most, but not all, of these patients had preexisting cardiovascular risk factors.
- Many of these events were reported to occur during or shortly after sexual activity, and a few were reported to occur shortly after the use of tadalafil without sexual activity.
- Others were reported to have occurred hours to days after the use of tadalafil and sexual activity.
- It is not possible to determine whether these events are related directly to tadalafil, to sexual activity, to the patient’s underlying cardiovascular disease, to a combination of these factors, or to other factors [see Warnings and Precautions ( 5.1 )].
- Body as a Whole — hypersensitivity reactions including urticaria, Stevens-Johnson syndrome, and exfoliative dermatitis Nervous — migraine, seizure and seizure recurrence, transient global amnesia Ophthalmologic — visual field defect, retinal vein occlusion, retinal artery occlusion Non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported rarely postmarketing in temporal association with the use of PDE5 inhibitors, including tadalafil.
- Most, but not all, of these patients had underlying anatomic or vascular risk factors for development of NAION, including but not necessarily limited to:
- low cup to disc ratio ("crowded disc"), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia, and smoking [see Warnings and Precautions ( 5.4 )].
- Otologic — Cases of sudden decrease or loss of hearing have been reported postmarketing in temporal association with the use of PDE5 inhibitors, including tadalafil.
- In some of the cases, medical conditions and other factors were reported that may have also played a role in the otologic adverse events.
- In many cases, medical follow-up information was limited.
- It is not possible to determine whether these reported events are related directly to the use of tadalafil, to the patient's underlying risk factors for hearing loss, a combination of these factors, or to other factors [see Warnings and Precautions ( 5.5 )].
- Urogenital — priapism [see Warnings and Precautions ( 5.3 )].
Quoted from the official label, section “Adverse Reactions”.
What to discuss with your doctor
- 17.1 Nitrates "See FDA-approved patient labeling (Patient Information)" Physicians should discuss with patients the contraindication of tadalafil tablets with regular and/or intermittent use of organic nitrates.
- Patients should be counseled that concomitant use of tadalafil tablets with nitrates could cause blood pressure to suddenly drop to an unsafe level, resulting in dizziness, syncope, or even heart attack or stroke.
- Physicians should discuss with patients the appropriate action in the event that they experience anginal chest pain requiring nitroglycerin following intake of tadalafil tablets.
- In such a patient, who has taken tadalafil tablets, where nitrate administration is deemed medically necessary for a life-threatening situation, at least 48 hours should have elapsed after the last dose of tadalafil tablets before nitrate administration is considered.
- In such circumstances, nitrates should still only be administered under close medical supervision with appropriate hemodynamic monitoring.
- Therefore, patients who experience anginal chest pain after taking tadalafil tablets should seek immediate medical attention [see Contraindications ( 4.1 ) and Warnings and Precautions ( 5.1 )].
- 17.2 Guanylate Cyclase (GC) Stimulators Physicians should discuss with patients the contraindication of tadalafil tablets with any use of a GC stimulator, such as riociguat, for pulmonary arterial hypertension.
- Patients should be counseled that the concomitant use of tadalafil tablets with GC stimulators may cause blood pressure to drop to an unsafe level.
- 17.3 Cardiovascular Considerations Physicians should consider the potential cardiac risk of sexual activity in patients with preexisting cardiovascular disease.
- Physicians should advise patients who experience symptoms upon initiation of sexual activity to refrain from further sexual activity and seek immediate medical attention [see Warnings and Precautions ( 5.1 )].
- 17.4 Concomitant Use with Drugs Which Lower Blood Pressure Physicians should discuss with patients the potential for tadalafil tablets to augment the blood-pressure-lowering effect of alpha-blockers, and antihypertensive medications [see Warnings and Precautions ( 5.6 ), Drug Interactions ( 7.1 ), and Clinical Pharmacology ( 12.2 )].
- 17.5 Potential for Drug Interactions When Taking Tadalafil Tablets for Once Daily Use Physicians should discuss with patients the clinical implications of continuous exposure to tadalafil when prescribing tadalafil tablets for once daily use, especially the potential for interactions with medications (e.g., nitrates, alpha-blockers, antihypertensives and potent inhibitors of cytochrome P450 3A4) and with substantial consumption of alcohol. [see Dosage and Administration ( 2.7 ), Warnings and Precautions ( 5.6 ), Drug Interactions ( 7.1 , 7.2 ), Clinical Pharmacology ( 12.2 ), and Clinical Studies ( 14.2 )].
- 17.6 Priapism There have been rare reports of prolonged erections greater than 4 hours and priapism (painful erections greater than 6 hours in duration) for this class of compounds.
- Priapism, if not treated promptly, can result in irreversible damage to the erectile tissue.
- Physicians should advise patients who have an erection lasting greater than 4 hours, whether painful or not, to seek emergency medical attention.
- Sudden Loss of Vision Physicians should advise patients to
- stop use of all PDE5 inhibitors, including tadalafil tablets, and seek medical attention in the event of a sudden loss of vision in one or both eyes.
- Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision, including possible permanent loss of vision, that has been reported rarely postmarketing in temporal association with the use of all PDE5 inhibitors.
- Physicians should discuss with patients the increased risk of NAION in individuals who have already experienced NAION in one eye.
- Physicians should also discuss with patients the increased risk of NAION among the general population in patients with a "crowded" optic disc, although evidence is insufficient to support screening of prospective users of PDE5 inhibitors, including tadalafil tablets, for this uncommon condition [see Warnings and Precautions ( 5.4 ) and Adverse Reactions ( 6.2 )].
- 17.8 Sudden Hearing Loss Physicians should advise patients to stop taking PDE5 inhibitors, including tadalafil tablets, and seek prompt medical attention in the event of sudden decrease or loss of hearing.
- These events, which may be accompanied by tinnitus and dizziness, have been reported in temporal association to the intake of PDE5 inhibitors, including tadalafil tablets.
- It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors [see Adverse Reactions ( 6.1 , 6.2 )].
- 17.9 Alcohol Patients should be made aware that both alcohol and tadalafil tablets, a PDE5 inhibitor, act as mild vasodilators.
- When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased.
- Therefore, physicians should inform patients that substantial consumption of alcohol (e.g., 5 units or greater) in combination with tadalafil tablets can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache [see Warnings and Precautions ( 5.9 ), Drug Interactions ( 7.1 ), and Clinical Pharmacology ( 12.2 )].
- 17.10 Sexually Transmitted Disease The use of tadalafil tablets offers no protection against sexually transmitted diseases.
- Counseling of patients about the protective measures necessary to guard against sexually transmitted diseases, including Human Immunodeficiency Virus (HIV) should be considered.
- 17.11 Recommended Administration Physicians should instruct patients on the appropriate administration of tadalafil tablets to allow optimal use.
- For tadalafil tablets for use as needed in men with ED, patients should be instructed to take one tablet at least 30 minutes before anticipated sexual activity.
- In most patients, the ability to have sexual intercourse is improved for up to 36 hours.
- For tadalafil tablets for once daily use in men with ED or ED/BPH, patients should be instructed to take one tablet at approximately the same time every day without regard for the timing of sexual activity.
- Tadalafil tablet is effective at improving erectile function over the course of therapy.
- For tadalafil tablets for once daily use in men with BPH, patients should be instructed to take one tablet at approximately the same time every day.
