Additional Information

Why is this medication prescribed

Nifedipine is used to treat high blood pressure. It relaxes your blood vessels so your heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart to control chest pain (angina). If taken regularly, nifedipine controls chest pain, but it does not stop chest pain once it starts. Your doctor may give you a different medication to take when you have chest pain.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Other uses for this medicine

Nifedipine is also used sometimes to treat migraine headaches, Raynaud's syndrome, congestive heart failure, and cardiomyopathy. Talk to your doctor about the possible risks of using this drug for your condition.

What other information should I know

Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to nifedipine.

Good dental hygiene decreases the chance and severity of gum swelling. Brush your teeth regularly and schedule dental cleanings every 6 months.

The extended-release tablet does not dissolve in the stomach after being swallowed. It slowly releases medicine as it passes through your small intestines. It is not unusual to see the tablet shell in the stool.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
