Drug class: Angiotensin II inhibitors with calcium channel blockers

Medically reviewed by Sanjai Sinha, MD. Last updated on Apr 15, 2024.

What is Azor?

Azor contains a combination of amlodipine and olmesartan.

Amlodipine is a calcium channel blocker. It works by relaxing the muscles of your heart and blood vessels.

Olmesartan is an angiotensin II receptor antagonist (sometimes called an ARB). Olmesartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Azor is used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.

Warnings

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

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

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.

Call your doctor at once if you have swelling in your hands or feet, rapid weight gain, pounding heartbeats or fluttering in your chest, urinating less than usual, jaundice (yellowing of the skin or eyes), chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling, or if you feel like you might pass out.

Before taking this medicine

You should not use Azor if you are allergic to amlodipine or olmesartan.

If you have diabetes, do not use Azor together with any medication that contains aliskiren (a blood pressure medicine).

You may also need to avoid taking amlodipine and olmesartan with aliskiren if you have kidney disease.

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

• kidney disease;

• liver disease;

• coronary artery disease;

• angina (chest pain), congestive heart failure;

• high levels of potassium in your blood;

• if you are on a low-salt diet;

• if you are 75 years or older; or

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

You should not breastfeed while using this medicine.

Azor is not approved for use by anyone younger than 18 years old.

How should I take Azor?

Take Azor exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

You may take Azor with or without food.

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

Certain conditions can cause your blood pressure to get too low. This includes vomiting, diarrhea, or heavy sweating. Call your doctor if you are sick with vomiting or diarrhea.

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

Keep using Azor 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.
