Hello, Erectile dysfunction has not been reported to date with amlodipine or valsartan. In-fact valsartan (angiotensin receptor blocker) itself can help to improve ED. My advice is to get investigations done for the exact reason for erectile dysfunction. There are many causes for ED like- -Heart disease and narrowing of blood vessels -Diabetes -High blood pressure -High cholesterol -Obesity and metabolic syndrome -Parkinson s disease -Multiple sclerosis You have to consult a physician to rule out it. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Hiren Hirpara
