DynaCirc

Generic name: Isradipine

Why is DynaCirc prescribed?

DynaCirc, a type of medication called a calcium channel blocker, is prescribed for the treatment of high blood pressure. It is effective when used alone or with a thiazide-type diuretic to flush excess water from the body. Calcium channel blockers ease the workload of the heart by slowing down the passage of nerve impulses through the heart muscle, thereby slowing the beat. This improves blood flow through the heart and throughout the body and reduces blood pressure. A controlled-release version of this drug (DynaCirc CR) maintains lower blood pressure for 24 hours.

Most important fact about DynaCirc

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

How should you take DynaCirc?

Take this medication exactly as prescribed, even if your symptoms have disappeared. Try not to miss any doses. If DynaCirc is not taken regularly, your condition may worsen.

Swallow the capsule or tablet whole, without crushing or chewing it.

• If you miss a dose...
  Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time.

• Storage instructions...
  Store at room temperature, away from light, in a tightly closed container.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking DynaCirc.

• Side effects may include:
  Dizziness, fluid retention, flushing, headache, pounding heartbeat

Why should DynaCirc not be prescribed?

If you are sensitive to or have ever had an allergic reaction to DynaCirc or other calcium channel blockers such as bepridil and nifedipine, you should not take this medication. Tell your doctor about any drug reactions you have experienced.
