Do not take it if
Sotradecol (sodium tetradecyl sulfate injection) is contraindicated in previous hypersensitivity reactions to the drug; in acute superficial thrombophlebitis; valvular or deep vein incompetence; huge superficial veins with wide open communications to deeper veins; phlebitis migrans; acute cellulitis; allergic conditions; acute infections; varicosities caused by abdominal and pelvic tumors unless the tumor has been removed; bedridden patients; such uncontrolled systemic diseases as diabetes, toxic hyperthyroidism, tuberculosis, asthma, neoplasm, sepsis, blood dyscrasias and acute respiratory or skin diseases.

How to take it
These directions are for this exact strength and form. Another one is different.
- Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration.
- Do not use if precipitated or discolored.
- Sotradecol (sodium tetradecyl sulfate injection) is for intravenous use only.
- The strength of solution required depends on the size and degree of varicosity.
- In general, the 1% solution will be found most useful with the 3% solution preferred for larger varicosities.
- The dosage should be kept small, using 0.5 mL to 2 mL (preferably 1 mL maximum) for each injection, and the maximum single treatment should not exceed 10 mL.
Quoted from the official label, section “Dosage & Administration”.
Other warnings
- Sotradecol (sodium tetradecyl sulfate injection) should only be administered by a healthcare professional experienced in venous anatomy and the diagnosis and treatment of conditions affecting the venous system and familiar with proper injection technique.
- Severe adverse local effects, including tissue necrosis, may occur following extravasation; therefore, extreme care in intravenous needle placement and using the minimal effective volume at each injection site are important.
- Emergency resuscitation equipment should be immediately available.
- Allergic reactions, including fatal anaphylaxis, have been reported.
- As a precaution against anaphylactic shock, it is recommended that 0.5 mL of Sotradecol be injected into a varicosity, followed by observation of the patient for several hours before administration of a second or larger dose.
- The possibility of an anaphylactic reaction should be kept in mind, and the physician should be prepared to treat it appropriately.
- Because of the danger of thrombosis extension into the deep venous system, thorough preinjection evaluation for valvular competency should be carried out and slow injections with a small amount (not over 2 mL) of the preparation should be injected into the varicosity.
- Deep venous patency must be determined by noninvasive testing such as duplex ultrasound.
- Venous sclerotherapy should not be undertaken if tests such as Trendelenberg and Perthes, and angiography show significant valvular or deep venous incompetence.
- The development of deep vein thrombosis and pulmonary embolism have been reported following sclerotherapy treatment of superficial varicosities.
- Patients should have post-treatment follow-up of sufficient duration to assess for the development of deep vein thrombosis.
- Embolism may occur as long as four weeks after injection of sodium tetradecyl sulfate.
- Adequate post-treatment compression may decrease the incidence of deep vein thrombosis.
- Arterial Embolism Stroke, transient ischemic attack, myocardial infarction, and impaired cardiac function have been reported in close temporal relationship with STS administration.
- These events may be caused by air embolism
- when using the product foamed with room air (high nitrogen concentration) or thromboembolism.
- The safety and efficacy of STS foamed with room air has not been established and its use should be avoided.
- GENERAL Extreme caution must be exercised in the presence of underlying arterial disease such as marked peripheral arteriosclerosis or thromboangiitis obliterans (Buerger’s Disease).
- GENERAL Extreme caution must be exercised in the presence of underlying arterial disease such as marked peripheral arteriosclerosis or thromboangiitis obliterans (Buerger’s Disease).
