Calan SR Oral

Generic Name: VERAPAMIL EXTENDED-RELEASE - ORAL
Pronounced: (ver-APP-uh-mill)

Calan SR Oral Uses

Verapamil is used with or without other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Verapamil is called a calcium channel blocker. It works by relaxing blood vessels so blood can flow more easily. This medication may also affect heart rate.



How To Use Calan SR Oral

Take this medication by mouth, usually once daily in the morning with food or as directed by your doctor.

Swallow the tablet whole. If you cannot swallow a whole tablet, you may cut it in half to make swallowing easier. Do not crush or chew the tablet. Doing so can destroy the long action of the drug and may increase side effects.

Avoid eating grapefruit or drinking grapefruit juice while being treated with this medication unless your doctor instructs you otherwise. Grapefruit juice can increase the amount of certain medications in your bloodstream. Consult your doctor or pharmacist for more details.

The dosage is based on your age, medical condition, body size and response to therapy.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. For the treatment of high blood pressure, it may take up to a week before the full benefit of this drug takes effect. If used for angina, this medication must be taken regularly to be effective. It should not be used to treat angina when it occurs. Use other medications (e.g., sublingual nitroglycerin) to relieve an angina attack as directed by your doctor. Consult your doctor or pharmacist for details.

Do not suddenly stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.

Inform your doctor if your condition worsens (e.g., your routine blood pressure readings increase).
