Get Procardia Online

Procardia (nifedipine) is prescribed primarily to treat high blood pressure (hypertension) and chronic stable angina (chest pain caused by reduced blood flow to the heart). By relaxing and widening blood vessels, it makes it easier for the heart to pump blood and reduces episodes of chest pain.

Nifedipine is a calcium channel blocker. It prevents calcium from entering the smooth muscle cells of artery walls, which causes those muscles to relax. The resulting widening of the arteries reduces resistance to blood flow and lowers blood pressure.

Procardia is an immediate-release form of nifedipine, while Procardia XL is an extended-release formulation taken once daily. The extended-release version provides more consistent blood levels throughout the day and is more commonly prescribed for long-term blood pressure management.

Common side effects include flushing, headache, dizziness, swelling in the ankles or feet (peripheral edema), and a sensation of warmth. These are often related to the blood vessel-widening effect of the medication and may lessen over time. Contact your doctor if side effects are severe or persistent.

Procardia can be combined with other antihypertensive agents, but the combination must be supervised by a physician because it can cause blood pressure to drop too low. Be sure to disclose all medications, supplements, and herbal products during your Doctronic evaluation.

Grapefruit and grapefruit juice should be avoided because they inhibit the enzyme that breaks down nifedipine, which can raise drug levels in the blood to potentially unsafe levels. Certain antibiotics, antifungals, and other heart medications can also interact with nifedipine, so a full medication review is important.
