My brother has been ill from taking too many chemicals daily! I need to know why? how are these pills conflicting with each other, and causing him such harm! My Brother is always tire, dizzy, heart palpitation, hand shaky, etc... Currently he takes the following:Two for Cholesterol: Ranexa and Gemfibrozil, three for Diabetics, and one for Arthritis: Ranexa ,Gemfibrozil ,Metformin , Gabapentin ,Glimepiride & Buprofen. Please advise, much appreciate it... Thanks. Bella De Soto
