Zyban Side Effects

Like all medicines, this medicine can cause side effects, although not everyone gets them.
Fits (seizures)
Approximately 1 in every 1,000 people taking Zyban is at risk of having a fit.
Symptoms of a fit include convulsions and usually loss of consciousness. Someone who has had a fit
may be confused afterwards and may not remember what has happened.
Fits are more likely if you take too much, if you take some other medicines or if you are at higher than usual risk of fits

If you have a fit, tell your doctor when you have recovered. Don’t take any more Zyban.
