Hi, I have been taking zen-retard 200 mg 1 tablet a day since more then 12 years, i have had seizers in between when i was stressful and stopped taking tablets, I have not faced any issue as long as i am not missing the tablets. Now , what i wanted to know is , will there be any side effects in long term if i continue using Zenretard 200 mg per day, i have seen lot of side effects listed in some of the websites but they may change from person to person. Could you please kindly clarify Regards, raj
