When should I take verapamil?

"How should I use verapamil?
Use verapamil exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Verapamil injection is given into a vein by a health care provider. Your heart rate will be constantly monitored using an electrocardiogram or ECG (sometimes called an EKG). Your blood pressure and other vital signs will also be watched closely.

Verapamil oral is taken by mouth. Your pharmacist can provide more information about how to take the tablets or capsules.

Your dose needs may change if you switch to a different brand, strength, or form of this medicine.

Some forms of verapamil oral cannot be crushed or chewed, and some forms can be opened and mixed with applesauce. Ask your pharmacist how to take this medicine.

Your blood pressure and liver function will need to be checked often.

If you have high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms."
