Drugs that act directly on the renin-angiotensin system can cause injury or death to the developing fetus when used during the second and third trimesters. Stop therapy as soon as possible when pregnancy is detected .
Angiotensin II Receptor Antagonist
Uses of This Medicine:
Candesartan is used alone or together with other medicines to treat high blood pressure (hypertension) in adults and children 1 to 16 years of age. High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Candesartan is an angiotensin II receptor blocker. It works by blocking the action of a substance in the body that causes blood vessels to tighten. As a result, candesartan relaxes blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Candesartan is also used to treat heart failure in adults and cut down on the number of hospital visits for heart problems.
This medicine is available only with your doctor's prescription.
Before Using This Medicine:

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of candesartan in children 1 to 16 years of age.

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of candesartan in the elderly. However, elderly patients may be more sensitive to the effects of candesartan than younger adults, and are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving candesartan.
