Recently few months back I developed Discathania and now my dosage of Syncapone is reduced and Parkitidine 100 mg 1-0-1-0 is strarted. I found that I lost weight of about 6 kgs in two months. I am physically fit, no exertion or tiredness and work from 9 am to 9 PM can you advise why my weight lossing is it due to this Parkitidine ??
