Lisinopril side effects

Lisinopril is a treatment for high blood pressure which belongs to a group of medications known as ACE (angiotensin-converting-enzyme) blockers, which work by constricting the blood vessels in order to cause them to relax, making it easier for the blood to circulate and relieving tension in the heart.

ACE blockers are generally considered to be relatively safe medications, however on some occasions patients may experience side effects.
