General Information

Nifedipine is indicated to prevent certain types of chest pain called angina. Angina is caused by reduced blood flow to the heart. This medication allows you to exercise more and lessen the frequency of angina attacks. To be effective, this must be taken regularly.

How does Nifedipine work?

When there is less resistance in the arteries, the heart does not work as hard to pump blood around the body. Nifedipine relaxes and widens the arteries that supply blood and oxygen to the heart muscle itself. This allows Nifedipine to prevent the painful angina attacks that can happen. It is when the heart does not get enough oxygen for the work it is doing.

Why use Nifedipine?

Nifedipine is in the class of calcium-channel blockers. This relaxes the blood vessels so the heart does not have to pump as hard. By increasing the supply of blood and oxygen to the heart it controls chest pain. Nifedipine is formulated as a soft gelatin capsule for oral use. Each capsule contains 10 mg of Nifedipine. The Food and Drug Administration (FDA) has already approved this medication.

How to use Nifedipine?

The recommended dosage for Nifedipine is based on your condition, age, and response. You must follow the instructions given by your doctor. Do not take this medicine for longer than recommended or in larger or smaller amounts.
