Zestril (lisinopril) is a medication used to treat hypertension (high blood pressure). It is an ACE inhibitor and works by relaxing blood vessels so that blood can flow more easily. Zestril is also used to protect kidney function in people with diabetes. It is available in generic and brand versions. Generic lisinopril is covered by most Medicare and insurance plans, but some pharmacy coupons or cash prices may be lower. The brand names for lisinopril are Prinivil and Zestril.

Lisinopril is also available as an oral solution. This drug may be used as part of a combination therapy. This means you may need to take it with other drugs. When used alone, lisinopril is usually well tolerated. However, some people may experience side effects such as headache, dizziness, or rash.
