Sir, A neuro physio patient regularly uses both the tab ZYVEN OD PLUS 50 and Dozep 50 for 5 years. But for taking these medicine for long time she faces many side problems as high BP, liver weakness, constipation, and so on. If any circumstances she forgot to take the medicine she becomes very weak, severe headache, severe neuro pain and severe vomiting. Is there any reason for such severe vomiting? Is there any way to get rid of these medicine?
