Verapamil

Verapamil is a prescription calcium channel blocker used to help control certain heart and blood pressure conditions. It works by relaxing blood vessels and slowing the movement of calcium into heart and vessel muscle cells, which can reduce how hard the heart has to work.

It is used for high blood pressure, angina, and certain abnormal heart rhythms. Verapamil may not be suitable for everyone, especially people with very low blood pressure, some heart rhythm problems, or severe heart failure. Take only as prescribed and tell your clinician about all medicines you use.
