What is enalapril?
What is enalapril?
Enalapril is an ACE inhibitor that is used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.
Enalapril is also used to treat congestive heart failure.
Enalapril is also used to treat a disorder of the ventricles (the lower chambers of the heart that allow blood to flow out of the heart). This disorder can decrease the heart's ability to pump blood to the body.
Enalapril may also be used for purposes not listed in this medication guide.

You should not use enalapril if you are allergic to it, or if:
- you have hereditary angioedema;
- you recently took a heart medicine called sacubitril; or
- you have ever had a severe allergic reaction to any ACE inhibitor (benazepril, captopril, fosinopril, lisinopril, moexipril, perindopril, quinapril, ramipril, or trandolapril).
Do not take enalapril within 36 hours before or after taking medicine that contains sacubitril (such as Entresto).
If you have diabetes, do not use enalapril together with any medication that contains aliskiren (a blood pressure medicine).
You may also need to avoid taking enalapril with aliskiren if you have kidney disease.
Tell your doctor if you have ever had:
- kidney disease (or if you are on dialysis);
- liver disease; or
- an electrolyte imbalance (such as high levels of potassium in your blood).
Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. Enalapril can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.
You should not breast-feed while you are using enalapril.

How should I take enalapril?
How should I take enalapril?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Enalapril is usually given by injection only if you are unable to take the medicine by mouth. A healthcare provider will give you this injection as an infusion into a vein.
Your blood pressure will need to be checked often. Your kidney or liver function may also need to be tested.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking enalapril. This can lead to very low blood pressure, electrolyte disorders, or kidney failure.
If you need surgery, tell the surgeon ahead of time that you are using enalapril.
If you are being treated for high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.
Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
Store the liquid medicine in the refrigerator, do not freeze. Throw away any enalapril liquid not used within 60 days.
