Nifedipine


Nifedipine

Generic Name: Nifedipine (nye-FED-ih-peen)Brand Name: Procardia

Nifedipine is used for:

Treating certain kinds of angina (chest pain). It may also be used for other conditions as determined by your doctor.

Nifedipine is a calcium channel blocking agent. It works by interfering with the normal action of calcium in blood vessel constriction (relaxes the blood vessels) and heart muscle contraction (heart may beat with less force and pump out less blood) and nerve conduction in the heart (heart may beat more slowly and more regularly). Calcium channel blockers are used to dilate (widen) the arteries of the heart and other arteries (reduce angina chest pain and reduce elevated blood pressure), and stabilize the heart rhythm in conditions in which the heart is beating too fast or in an irregular rhythm (antiarrhythmic effects).

Do NOT use Nifedipine if:

  • you are allergic to any ingredient in Nifedipine

Contact your doctor or health care provider right away if any of these apply to you.
