Lisinopril Basics

Lisinopril is an angiotensin-converting-enzyme (ACE) inhibitor that treats heart failure, hypertension, and chronic renal failure. It prevents the hormone angiotensin-II from forming. Angiotensin-II causes vasoconstriction, or the constriction of blood vessels. When blood vessels constrict, blood pressure goes up. By stopping the formation of angiotensin-II, lisinopril lowers blood pressure. Lisinopril is used in dogs and cats.

This product requires a prescription from your veterinarian. It is available in 2.5mg, 5mg, 10mg, 20mg, and 30mg tablets.

Lisinopril Directions

Use as directed by your veterinarian. Follow the instructions printed on the prescription label. If your pet vomits after administration of lisinopril, try giving the medication with food. Do not stop giving lisinopril, even if your pet seems to be improving, unless instructed otherwise by your veterinarian.

Lisinopril Warnings

Keep out of the reach of children and pets. Do not use in pets with known ACE inhibitor sensitivity, renal insufficiency, or low sodium levels.
