Candesartan may cause injury or death to the fetus if taken during pregnancy. If you think you may be pregnant, contact your doctor right away. If you are planning to become pregnant, talk with your doctor about other treatment options.


Candesartan is used for:

Treating high blood pressure alone or with other medicines. It is used in certain patients to treat heart failure. It may also be used for other conditions as determined by your doctor.

Candesartan is an angiotensin II receptor blocker (ARB). It works by relaxing blood vessels. This helps to lower blood pressure.

Do NOT use candesartan if:

  • you are allergic to any ingredient in candesartan
  • you are pregnant
  • the patient is a child who has severe kidney problems
  • you are taking a medicine that contains aliskiren and you also have diabetes or kidney problems. Check with your doctor or pharmacist if you are not sure if a medicine you take contains aliskiren

Contact your doctor or health care provider right away if any of these apply to you.

Before using candesartan:

Some medical conditions may interact with candesartan. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are able to become pregnant
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have a history of angioedema (eg, swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; hoarseness), including angioedema caused by treatment with an angiotensin-converting enzyme (ACE) inhibitor (eg, lisinopril)
  • if you have a history of heart problems, blood vessel problems, blood flow problems, diabetes, or liver or kidney problems
  • if you have a history of stroke or recent heart attack
  • if you are dehydrated or have low blood volume
  • if you have electrolyte problems (eg, high blood potassium levels, low blood sodium levels) or are on a low-salt (sodium) diet
  • if you are on dialysis or are scheduled to have surgery or receive anesthesia
  • if you have had a kidney transplant

Some MEDICINES MAY INTERACT with candesartan. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Diuretics (eg, furosemide, hydrochlorothiazide) because the risk of low blood pressure may be increased
  • Potassium-sparing diuretics (eg, spironolactone, triamterene) or potassium supplements because the risk of high blood potassium levels may be increased
  • ACE inhibitors (eg, lisinopril) or aliskiren because the risk of certain side effects (eg, kidney problems, high blood potassium levels, low blood pressure) may be increased
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, celecoxib, ibuprofen, indomethacin) because they may decrease candesartan's effectiveness and the risk of serious kidney problems may be increased
  • Lithium because the risk of its side effects may be increased by candesartan

This may not be a complete list of all interactions that may occur. Ask your health care provider if candesartan may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
