About this drug

Enalapril (ee-NAL-a-pril) is used to treat high blood pressure and heart failure. It is also used to treat kidney problems in people with diabetes. It is an ACE (angiotensin converting enzyme) inhibitor.

  • Cough

  • Joint pain
  • Increased potassium level
  • Passing less urine

If any of these side effects become severe or bother you, call your doctor. Do not take over-the-counter medicine for your symptoms.

Drug interactions

Enalapril can increase potassium levels. Too much potassium can be dangerous. Potassium
supplements and potassium-sparing diuretics (amiloride, spironolactone, triamterene) can
increase the levels of potassium in your body. These drugs may be used with enalapril, but
only under your doctor’s supervision. Tell your doctor or pharmacist about any prescription
medicine, over-the-counter medicine, or herbal products that you are taking. He or she will check for interactions.

If you miss a dose

If you miss a medicine dose, take it as soon as you remember. If it is within 2 hours of the time for your next dose, skip the missed dose. Take your next dose at its scheduled time, and continue your usual dosing schedule. Do not “double up” on doses to catch up.

Avoid salt and salt substitutes

While you are on this medicine, you should avoid salt substitutes, because most contain potassium. You also should avoid having too much salt (sodium) in your diet. Do not stop taking this drug unless your doctor tells you to.

How to take this medicine

This medicine may be taken with or without food. It usually is taken once or twice daily. If you are to take 2 doses daily, take one in the morning and one in the evening. The tablets have small lines down the center. They may be broken in half to provide the correct dosage.
