Procardia : Uses, Side Effects, Interactions & More

Why is this medication prescribed?
Procardia (Nifedipine) is used to treat high blood pressure and control angina (chest pain). Procardia is in a class of medications called calcium channel blockers. It lowers blood pressure by relaxing the blood vessels so the heart doesn’t have to pump as hard. Controls chest pain by increasing the supply of blood and oxygen to the heart.

High blood pressure is a common condition and, when left untreated, it can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs can cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medications, making lifestyle changes will also help control your blood pressure. These changes include eating a diet low in fat and salt, maintaining a healthy weight, exercising for at least 30 minutes most days, not smoking, and consuming alcohol in moderation.

How should this medicine be used?
Procardia (Nifedipine) comes as capsules and an extended-release (long-acting) tablet to take by mouth. The capsule is generally taken three to four times a day. The extended-release tablet should be taken once a day on an empty stomach, 1 hour before or 2 hours after a meal. To remind you to take Procardia, take it at around the same time every day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take Procardia exactly as directed. Do not take more or less or take it more often than prescribed by your doctor.

Swallow the extended-release tablets whole; do not split, chew, or crush them.

Your doctor will likely prescribe a low dose of Procardia and increase it gradually, usually once every 7 to 14 days.

If taken regularly, Procardia controls chest pain, but does not stop it once it starts. Your doctor may prescribe a different medicine for you to take when you have chest pain.

Procardia controls high blood pressure and chest pain (angina), but it does not cure them. Keep taking Procardia even if you feel fine. Do not stop taking Procardia without consulting your doctor. Your doctor will likely reduce your dose gradually.

Other uses for this medicine
Procardia is also sometimes used to treat preterm labor and Raynaud’s syndrome. Talk to your doctor about the possible risks of using this drug for your condition.

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

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • Tell your doctor what herbal products you are taking, especially St. John’s wort.
  • Tell your doctor if you have or have ever had a narrowing or blockage of your digestive system or any other condition that causes food to move through your digestive system more slowly; or heart, liver, or kidney disease. Also tell your doctor if you have had a myocardial infarction (MI) in the past 2 weeks.

  • If you are having surgery, including dental surgery, tell your doctor or dentist that you are taking Procardia.
  • Ask your doctor about the safe use of alcoholic beverages while taking Procardia. Alcohol can make the side effects of Procardia worse.

What should I know about storage and disposal of this medication?
Keep this medicine in the container it came in, tightly closed, and out of the reach of children. Store at room temperature, away from light and excess heat and humidity (not in the bathroom).

It is important to keep all medicines out of the sight and reach of children, since many containers (such as those containing weekly pills and those for eye drops, creams, patches and inhalers) are not child-resistant and small children can easily open them. To protect young children from poisoning, always close the safety caps and immediately place the medicine in a safe place, one that is upright and out of their sight and reach. http://www.upandaway.org

Unnecessary medications must be disposed of in special ways to ensure they cannot be consumed by pets, children, and others. However, you should not flush this medicine down the toilet. Instead, the best way to dispose of your medications is through a drug take-back program. Talk to your pharmacist or contact your local garbage / recycling department to find out about take-back programs in your community. See the FDA Safe Drug Disposal website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What other information should I know?

If you are taking certain extended-release tablets (Afeditab CR, Procardia XL), you may notice something that looks like a tablet in your stool. This is just the empty tablet shell, and this does not mean that you have not received your full dose of medicine.

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