Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor that works to dilate blood vessels. This action is beneficial in the treatment of both heart failure and hypertension (high blood pressure) in dogs and cats. Lisinopril use in veterinary medicine is considered extra-label.
heart failure, hypertension (high blood pressure)
Angiotensin-converting enzyme (ACE) inhibitor that prevents the formation of substances responsible for constricting the blood vessels.
Lisinopril should be stored in a childproof container at room temperature in a safe location out of the reach of children and animals.
It is best to give the medication as directed without skipping doses. If you miss a dose, skip the one you missed and go back to the normal schedule. Do not give two doses at the same time.
Overdoses may cause lethargy, increased heart rate, vomiting, and hypotension (low blood pressure). Seek veterinary care immediately if you think your pet has had an overdose.
Insulin and oral antidiabetic medication, diuretics (furosemide, spironolactone, hydrochlorothiazide), lithium, other medication to lower blood pressure, non-steroidal anti-inflammatory drugs (NSAIDs), and potassium supplements may all interact with lisinopril. Discuss all medications and possible interactions with your pet’s veterinarian.
Avoid use in patients with previous sensitivities to ACE inhibitors. Use with caution in animals with kidney disease, low sodium, or blood cell changes. Avoid use in pregnant animals and use caution in lactating animals.
