People who have chest pain (angina), high blood pressure, and certain types of irregular heart rhythms (arrhythmias) may benefit from using Calan® (verapamil hydrochloride). The prescription medication works by relaxing the blood vessels to improve blood flow. It comes in the form of a tablet, and it is usually taken three or four times daily.
Most people tolerate this drug well; and even when side effects occur, they are usually minor and easy to treat. Some side effects of the medicine include nausea, headaches, and dizziness. Before starting treatment, it's important to talk with your healthcare provider about any other medical conditions you have and any other medications you are taking. Also, be sure to tell your healthcare provider if you are pregnant, thinking of becoming pregnant, or breastfeeding.
