I recently had high blood pressure and a heart attack. I am 87 years old and take 80 Mg of Lipitor, .125 of Digoxin, 25 Mg of Metoprolol, 10 Mg of Xarelto, 30 Mg of Diltiazem 3X a day and 15 Mg of Temazepan at night if needed. I was taking 120 Mg Diltiazem once a day before and Plavix once a day. I have been light headed, dizzy at times and very weak since the medication change, Could the symptoms be the change in medication?
