Used For
Hypertension
How it works
Verapamil is in a class of medications called calcium-channel blockers. It works by relaxing the blood vessels so the heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart and slows electrical activity in the heart to control the heart rate.

PRECAUTIONS
Precaution
Since verapamil is highly metabolized by the liver, it should be administered cautiously to patients with impaired hepatic function.
WARNINGS
Warning 1
Occasionally, the pharmacologic action of verapamil may produce a decrease in blood pressure below normal levels, which may result in dizziness or symptomatic hypotension.
Warning 2
Verapamil has a negative inotropic effect, which in most patients is compensated by its afterload reduction (decreased systemic vascular resistance) properties without a net impairment of ventricular performance.
Warning 3
Elevations of transaminases with and without concomitant elevations in alkaline phosphatase and bilirubin have been reported.
