## What is lisinopril?

Lisinopril is an ACE inhibitor. ACE stands for angiotensin converting enzyme.

Lisinopril is used to treat high blood pressure (hypertension) in adults and children who are at least 6 years old.

Lisinopril is also used to treat congestive heart failure in adults, or to improve survival after a heart attack.

## Warnings

Do not use lisinopril if you are pregnant. It could harm the unborn baby. Stop using this medicine and tell your doctor right away if you become pregnant.

You should not use this medicine if you have ever had angioedema. Do not take lisinopril within 36 hours before or after taking medicine that contains sacubitril (such as Entresto).

If you have diabetes, do not use lisinopril together with any medication that contains aliskiren (such as Amturnide, Tekturna, Tekamlo).

You may also need to avoid taking lisinopril with aliskiren if you have kidney disease.

## Before taking this medicine

- have a history of angioedema;

- recently took a heart medicine called sacubitril; or

- are allergic to any other ACE inhibitor, such as benazepril, captopril, enalapril, fosinopril, moexipril, perindopril, quinapril, ramipril, or trandolapril.

Do not take lisinopril within 36 hours before or after taking medicine that contains sacubitril (such as Entresto).

If you have diabetes, do not use lisinopril together with any medication that contains aliskiren (such as Tekturna or Tekamlo).

You may also need to avoid taking lisinopril with aliskiren if you have kidney disease.

To make sure this medicine is safe for you, tell your doctor if you have ever had:

- kidney disease (or if you are on dialysis);

- liver disease; or

- high levels of potassium in your blood.

Do not use lisinopril if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. This medicine can cause injury or death to the unborn baby if you take the medicine during your second or third trimester. Use effective birth control while taking this medicine.

## How should I take lisinopril?

Take lisinopril exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Drink plenty of water each day while you are taking this medicine.

Lisinopril can be taken with or without food.

Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Your blood pressure will need to be checked often. Your kidney function and electrolytes may also need to be checked.

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 this medicine. This can lead to very low blood pressure, electrolyte disorders, or kidney failure while you are taking lisinopril.

If you need surgery, tell the surgeon ahead of time that you are using lisinopril.

If you have high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Store at room temperature away from moisture and heat. Do not freeze the oral liquid.

## Dosing information

Usual Adult Dose for Hypertension:

Initial dose: 10 mg orally once a day; 5 mg orally once a day
Maintenance dose: 20 to 40 mg orally once a day
Maximum dose: 80 mg orally once a day
Comments:
-The initial dose is 5 mg orally once a day in patients receiving a diuretic.
-The 80 mg dose is used but does not appear to give greater effect.
-If blood pressure is not controlled with lisinopril alone, a low dose of a diuretic may be added (e.g., hydrochlorothiazide, 12.5 mg). After the addition of a diuretic, it may be possible to reduce the dose of lisinopril.

Usual Adult Dose for Congestive Heart Failure:

Initial dose: 2.5 to 5 mg orally once a day
Maintenance dose: Dosage should be increased as tolerated
Maximum dose: 40 mg orally once a day
Comments:
-The diuretic dose may need to be adjusted to help minimize hypovolemia, which may contribute to hypotension. The appearance of hypotension after the initial dose of lisinopril does not preclude subsequent careful dose titration with the drug.

Usual Adult Dose for Myocardial Infarction:

Initial dose: 5 mg orally (within 24 hours of the onset of acute myocardial infarction)
Subsequent doses: 5 mg orally after 24 hours, then 10 mg orally after 48 hours.
