Lotensin (benazepril) is an ACE inhibitor. ACE stands for angiotensin converting enzyme.

Lotensin is used to treat high blood pressure (hypertension).

Lotensin may also be used for purposes not listed in this medication guide.

Important information

Do not use Lotensin if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away.

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

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

Before taking this medicine

You should not use Lotensin if you are allergic to benazepril, or if:

  • you have hereditary angioedema;

  • you recently took a heart medicine called sacubatril; or

  • you have ever had a severe allergic reaction to any ACE inhibitor (captopril, enalapril, fosinopril, lisinopril, moexipril, perindopril, quinapril, ramipril, trandolapril).

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

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

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

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

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

  • liver disease;

  • any history of heart disease; or

  • if you have had an organ transplant.

Do not use Lotensin if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. Benazepril can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.

Benazepril can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are using this medicine.

Lotensin is not approved for use by anyone younger than 6 years old.

How should I take Lotensin?

Take Lotensin exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.

You may take Lotensin with or without food.

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

Your blood pressure will need to be checked often, and you may need frequent blood tests.

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 Lotensin.

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

Keep using this medicine as directed, 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.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid?

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

Avoid becoming overheated or dehydrated during exercise, in hot weather, or by not drinking enough fluids. Benazepril can decrease sweating and you may be more prone to heat stroke.

Drinking alcohol can further lower your blood pressure and may increase certain side effects of benazepril.

Do not use salt substitutes or potassium supplements while taking this medicine, unless your doctor has told you to.
