Candesartan cilexetil

Brand names: Atacand

Why is Candesartan cilexetil prescribed?

Atacand controls high blood pressure. It works by blocking the effect of a hormone called angiotensin II. Unopposed, this substance prompts the blood vessels to contract, an action that tends to raise blood pressure. Atacand relaxes and expands the blood vessels, allowing pressure to drop. The drug may be prescribed alone or with other blood pressure medications.

Most important fact about Candesartan cilexetil

You must take Atacand regularly for it to be effective. Since blood pressure declines gradually, it may be a couple of weeks before you get significant benefits from Atacand, and you must continue taking it even though you feel well. Atacand does not cure high blood pressure, it merely keeps it under control.

  • Storage instructions...Store at room temperature in a tightly sealed container.

What side effects may occur?

Special warnings about Candesartan cilexetil

Atacand can cause a severe drop in blood pressure, especially when you first start taking the drug. The problem is more likely to occur if your body's supply of water has been depleted by diuretics (water pills). Symptoms include light-headedness, dizziness, and faintness. Call your doctor if they occur. You may need to have your dose adjusted.

If you have heart failure, the initial usage of Atacan may cause not only a drop in blood pressure, but also a decline in potassium levels, especially if taken with diuretics

If you have kidney or liver disease, Atacand must be used with caution.

Possible food and drug interactions when taking Candesartan cilexetil

The chances of a drug interaction with Atacand are low. Check with your doctor, however, before combining it with lithium.

Special information if you are pregnant or breastfeeding

Atacand can cause injury or even death to an unborn child when used during the last 6 months of pregnancy. As soon as you learn that you are pregnant, stop taking Atacand and call your doctor.

It is not known whether Atacand appears in breast milk, but because of the potential risks to the nursing infant, it's considered best to avoid the drug while breastfeeding. You should decide whether to give up nursing or discontinue Atacand.

Recommended dosage for Candesartan cilexetil


Atacand can be taken once or twice a day in doses totaling 8 to 32 milligrams per day. However, the recommended starting dose is 16 milligrams taken once daily. If you are taking a diuretic (water pill) or if you have kidney or liver problems, your doctor will start you on a lower dose.
