1) What are the generic medicines that I should purchase for the following brands: Toprol XL 50 MG (one per day); (; Accupril 20 MG (three times per day); Norvasc 10 MG ( one per day). I can no longer afford the brands. 2.) I am taking all of these pills in the morning. A friend who is a physician, recently told me that I should take the Toprol at night.
