My wife has been taking Mazetol 200 for last 10 years now. She started this medicine in 2010. In last 10 years, after starting this medicine, she never had any seizures. But the doctor whom she consulted back in 2010 said that she can continue this medicine for longer duration and if a situation comes where it feels that there is no need to continue this medicine any further, then it should only be done after consulting a doctor. Without consulting a Doctor she should not stop the medicine. Since she didn't have any problem in last 10 years, we are now thinking about discontinuing the medicine. But wanted to know what should be procedure to stop this medicine? Another thing we wanted to know - is there any side effects of Mazetol 200 when in use for long duration? Please suggest/advise.
