Welcome to Just Answer and thanks for your question. How much of each are you taking? What is your blood pressure?
Thanks for the additional information. The Lopressor is a cardio-selective beta blocker (metoprolol) while Lotrel is a combination drug that is 10 mg amlodipine (a calcium channel blocker) plus 40 mg benazepril (an ACE inhibitor). You are getting the three best types of hypertension medications in just two pills. Normal dosage of Lopressor is 100-450 mg per day in two divided doses. We don't usually change drugs until the dosages of the ones someone is on are maxed out. Your doctor may want to increase the Lopressor, or go to Lopressor HCT 50/25 which also includes a diuretic.
