What is enalapril?
Enalapril is an ACE inhibitor. ACE stands for angiotensin converting enzyme.
Enalapril is used to treat high blood pressure (hypertension) and 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.
What is the most important information I should know about enalapril?
Do not use if you are pregnant. Stop using and tell your doctor right away if you become pregnant.
You should not use enalapril if you have ever had angioedema.
If you have diabetes or kidney disease, you may not be able to take enalapril if you are taking medication that contains aliskiren. Tell your doctor about all medicines you use.
Enalapril can cause kidney problems. Call your doctor at once if you have swelling, rapid weight gain, little or no urinating, or if you feel short of breath.
Enalapril can affect your heart or your electrolyte levels. Call your doctor if you have chest pain, pounding heartbeats or fluttering in your chest, a slow heart rate or weak pulse, a tingly feeling, muscle weakness, or muscle tightness or contraction.
What should I discuss with my healthcare provider before taking enalapril?

To make sure enalapril is safe for you, tell your doctor if you have:
