Procardia oral Uses

This medication is used to prevent certain types of chest pain (angina). It may allow you to exercise more and decrease the frequency of angina attacks. Nifedipine belongs to a class of medications known as calcium channel blockers. It works by relaxing blood vessels so blood can flow more easily. This medication must be taken regularly to be effective. It should not be used to treat attacks of chest pain when they occur. Use other medications (such as sublingual nitroglycerin) to relieve attacks of chest pain as directed by your doctor. Consult your doctor or pharmacist for details.

Older adults should discuss the risks and benefits of this medication with their doctor or pharmacist, as well as other possibly safer forms of nifedipine (such as the long-acting tablets).

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This medication may also be used to treat a certain blood circulation disorder (Raynaud's syndrome).

Procardia oral Interactions

See also the How to Use section.

Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: phenytoin, quinidine, tacrolimus.

Other medications can affect the removal of nifedipine from your body, which may affect how nifedipine works. Examples include cimetidine, azole antifungals (such as itraconazole), macrolide antibiotics (such as erythromycin), rifamycins (such as rifabutin), St. John's wort, drugs used to treat seizures (such as carbamazepine), among others.

Check the labels on all your medicines (such as cough-and-cold products, diet aids) because they may contain ingredients that could increase your heart rate and worsen chest pain (including caffeine, pseudoephedrine, phenylephrine). Ask your pharmacist about using these products safely.

Cimetidine is a nonprescription drug that is commonly used to treat extra stomach acid. Because cimetidine may interact with nifedipine, ask your pharmacist about other products to treat extra stomach acid.
