My husband suffered a heart attack four years ago now, and he has been on medication in one form or another ever since. He has a stand now, and will need medication for the rest of his life. He came back from the doctor with a new prescription a few days ago - this time for candesartan. Is this a medication that is high on side effects, or is candesartan low on side effects? What side effects are the most usual in candesartan, and how many patients get them?
