What is a generic medication?

Generic medications are significantly discounted copies of brand name medication that have the same active ingredients, intended use, dosage, side effects, effects, and route of administration as the original brand name medication. In other words, generic medications have the same pharmacological effects as their brand-name counterparts. Over half of all prescribed medications are for generic medications.

  • Cardizem Overview

    Diltiazem is used to prevent chest pain (angina). It may help to increase your ability to exercise and decrease how often you may get angina attacks. Diltiazem is called a calcium channel blocker. It works by relaxing blood vessels in the body and heart and lowers the heart rate. Blood can flow more easily and your heart works less hard to pump blood.

  • How to Use Cardizem

    Take Cardizem by mouth before meals and at bedtime as directed by your doctor, usually 3 to 4 times a day. Swallow the tablets whole. Do not split, crush, or chew the tablets.
