What is Procardia?

Procardia is in a group of drugs called calcium channel blockers. It works by relaxing the muscles of your heart and blood vessels.

Procardia is used to treat hypertension (high blood pressure) and angina (chest pain).

Procardia may also be used for purposes not listed in this medication guide.

Important Information

You should not use Procardia if you have severe coronary artery disease, or if you have had a heart attack within the past 2 weeks.

Before taking this medicine

You should not use Procardia if you are allergic to Procardia, if you have severe coronary artery disease, or if you have had a heart attack within the past 2 weeks.

To make sure Procardia is safe for you, tell your doctor if you have:

It is not known whether Procardia will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Nifedipine can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

The Procardia extended-release tablet may contain lactose. Talk to your doctor before using this form of nifedipine if you have galactose intolerance, or severe problems with lactose (milk sugar).

How should I take Procardia?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

You may need to take an extended-release tablet on an empty stomach. Follow the directions on your medicine label about taking this medication with or without food.

Do not crush, chew, or break an extended-release tablet. Swallow it whole.

Your blood pressure will need to be checked often and you may need other blood tests at your doctor's office.

Some tablet forms of nifedipine are made with a shell that is not absorbed or melted in the body. Part of the tablet shell may appear in your stool. This is a normal side effect of nifedipine and will not make the medication less effective.

If you need surgery, tell the surgeon ahead of time that you are using Procardia. You may need to stop using the medicine at least 36 hours before surgery.

You may have very low blood pressure while taking this medication. Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual.

If you are also taking a beta-blocker (atenolol, carvedilol, labetalol, metoprolol, nadolol, nebivolol, propranolol, sotalol, and others) you should not stop using the beta-blocker suddenly or you could have serious heart problems that will not be prevented by Procardia. Follow your doctor's instructions about tapering your beta-blocker dose.

You should not stop using Procardia suddenly. Stopping suddenly may make your condition worse.

If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Store at room temperature away from moisture, heat, and light.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking Procardia?
