Key Information

Y Enalapril is used to treat heart failure, high blood pressure, and some forms of kidney disease in dogs and cats.

Y It is usually well tolerated, but vomiting and diarrhea
can occur. May be given with or without food. If your pet vomits, stops eating, or acts sick after receiving it on an empty stomach, give with food or small treat to see if this helps. If vomiting continues, contact your veterinarian.

Y If a rash or signs of infection occur (eg, fever) contact your veterinarian immediately.

Y Very important to give as prescribed. Do not stop or reduce dosage without veterinarian’s guidance.

How is this medication useful?

Enalapril is used to help the heart perform more efficiently by opening up blood vessels and decreasing fluid retention in the body.

This drug is also used to protect the kidneys from certain diseases that affect them. You and your veterinarian can discuss why this drug is the most appropriate choice.

What should I tell my veterinarian to see if this medication can be safely given?

Many things might affect how well this drug will work in your an- imal. It is very important to discuss the following with your veter- inarian so together you can make the best decisions for treating your pet.

Y Other drugs can interact with this medication, so tell your veterinarian and pharmacist what medications (including vitamins, supplements, or herbal therapies) you give your pet, including the amount and time you give each.

Y Tell your veterinarian about any conditions or diseases your pet may have or had in the past.

Y If your pet is pregnant or nursing, talk to your veterinarian about the risks of using this drug. Enalapril has caused birth defects in humans and laboratory animals. Tell your veterinarian if your pet is pregnant or going to be bred while taking enalapril.

Y Tell your veterinarian and pharmacist about any medication side effects (including allergic reactions, lack of appetite, diarrhea, itching, hair loss) your pet has developed in the past.

When should this medication not be used or be used very carefully?

No drug is 100% safe in all patients, but your veterinarian will discuss with you any specific concerns about using this drug in your pet.

This drug SHOULD NOT be used in patients:
Y That have had an allergic (hypersensitive) or severe reaction to it or

other drugs like it (eg, ramipril, lisinopril, benazepril).

Y With certain heart conditions (eg, aortic stenosis, obstructive hypertrophic cardiomyopathy).

This drug should be used WITH CAUTION in patients:
Y That are dehydrated. If your pet is dehydrated, the drug may

cause toxicity. Be sure your pet has plenty of clean drinking water available.

Y Severe liver or kidney damage. This drug must be converted to its active form by the liver. If your pet has severe liver disease, this drug may not be effective. Enalapril is eliminated from the body by the kidneys. If your pet has serious kidney disease, your veterinarian will probably lower the dose of enalapril.

If your pet has any of these conditions or signs, talk to your veterinarian about the potential risks versus benefits.
