My husband has started having difficulty walking, wanting to lean forward and fall, also cannot get out of bed by himself. He is on Garapentin 10 mg bid, Pravachol 40 mg, Plavix 75 mg, ASa 325 mg, Niacin 500 mg, Vitamin D 400 mg, CoQ10, 200 mg, Corag 12.5 mg bid, Cozaar 25 mg, Vitamin E 800 mg,Proscar 5 mg, Prilosec 20 mg, and insulin. Could a combination of these drugs cause this?
