What Is Verapamil HCL 40mg?
Verapamil HCL is a calcium channel blocker sold under the brand name Calan. It works by relaxing blood vessels and slowing electrical conduction in the heart, which lowers blood pressure, reduces the heart's workload, and helps control certain rapid heart rhythms. The 40mg tablet is typically prescribed for patients who may respond to lower doses, such as older adults or people of smaller stature. Verapamil requires a valid prescription and is taken by mouth, usually several times a day as directed by your provider.
