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. It may also lower the heart rate.
How To Use Calan SR Oral
Take this medication by mouth with food, usually once daily in the morning or every 12 hours or as directed by your doctor.
You may cut the tablet in half, but do not crush or chew the tablet. Doing so can release all of the drug at once and may increase your risk of side effects.
The dosage is based on your medical condition and response to treatment.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.
For the treatment of high blood pressure, it may take a week before you get the full benefit of this drug. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.
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.
Tell your doctor if your condition does not improve or if it worsens (for example, your routine blood pressure readings remain high or increase).
