How it works
From the US prescribing label for the same active substance (Zonisamide). It describes the substance, not this exact product.
The precise mechanism(s) by which zonisamide exerts its antiseizure effect is unknown.
Zonisamide demonstrated anticonvulsant activity in several experimental models.
In the presence of food, the time to maximum concentration is delayed; occurring at 4-6 hours, but food has no effect on the bioavailability of zonisamide.

Safety of the active substance
From the US prescribing label for the same active substance (Zonisamide). It describes the substance, not this exact product.
- Zonisamide capsules are contraindicated in patients who have demonstrated hypersensitivity to sulfonamides or zonisamide.
The most common adverse reactions with zonisamide (an incidence at least 4% greater than placebo) in controlled clinical trials and shown in descending order of frequency were somnolence, anorexia, dizziness, ataxia, agitation/irritability, and difficulty with memory and/or concentration.
