Plendil

Why is Plendil prescribed?

Plendil is prescribed for the treatment of high blood pressure. It is effective alone or in combination with other high blood pressure medications. A type of medication called a calcium channel blocker, Plendil eases the workload of the heart by slowing down its muscle contractions and the passage of nerve impulses through it. This improves blood flow through the heart and throughout the body, reduces blood pressure, and helps prevent angina pain (chest pain, often accompanied by a feeling of choking, usually caused by lack of oxygen in the heart due to clogged arteries).

Most important fact about Plendil

If you have high blood pressure, you must take Plendil regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Plendil; you must continue taking it even if you are feeling well. Plendil does not cure high blood pressure; it merely keeps it under control.

How should you take Plendil?

Plendil can be taken with a light meal or without food. The tablets should be swallowed whole, not crushed or chewed.

Try not to miss any doses. If Plendil is not taken regularly, your blood pressure may increase.

--If you miss a dose...

Take the forgotten dose as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to your regular schedule. Never try to "catch up" by doubling the dose.

--Storage instructions...

Store at room temperature. Protect from light.

  Flushing, headache, swelling of the legs and feet

Why should Plendil not be prescribed?

If you are sensitive to or have ever had an allergic reaction to Plendil or other calcium channel blockers, such as Calan and Procardia, you should not take Plendil. Make sure your doctor is aware of any drug reactions you have experienced.

Special warnings about Plendil

Plendil can cause your blood pressure to become too low. If you feel light-headed or faint, or if you feel your heart racing or you experience chest pain, contact your doctor immediately.

If you have congestive heart failure, Plendil should be used with caution, especially if you are also taking one of the "beta-blocker" family of drugs, such as Inderal or Tenormin.

Your legs and feet may swell when you start taking Plendil, usually within the first 2 to 3 weeks of treatment.

If you have liver disease or are over age 65, your doctor should monitor your blood pressure carefully while adjusting your dosage of Plendil.

Your gums may become swollen and sore while you are taking Plendil. Good dental hygiene will help control this problem.
