VERAPAMIL in Calan
may interact with CALCIUM SALTS in Calcium Acetate
Calcium is responsible for many different functions in the body including the transmission of nerve signals and the contraction of muscles throughout the body. Because verapamil interferes with the body's ability to use calcium, this drug is sometimes given to regulate the beating of the heart muscle. It can also be used to prevent the muscles inside of blood vessels from contracting, thereby causing a decrease in blood pressure. Calcium citrate may cancel the effects of verapamil by making more calcium available for the body to use. To avoid problems, inform your doctor before using calcium citrate or any other calcium supplement while you are taking verapamil. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
