What this medicine is used for
The name of your medicine is APO-Candesartan. It contains the active ingredient candesartan cilexetil.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.
How it works
Candesartan is a type of medicine called an angiotensin II receptor inhibitor (or antagonist).
All people have blood pressure. This pressure helps to push blood all around your body. Your blood pressure changes during the day, depending on how busy you are or how you are feeling.
You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
Regular blood pressure checks are the only way of knowing that you have hypertension. There are usually no symptoms of hypertension and you may feel fine. If hypertension is not treated, serious health problems such as stroke or heart attack and heart or kidney failure may occur.
Candesartan lowers blood pressure by dilating (expanding) small blood vessels from the heart, letting the blood be pumped around the body more easily.
Heart failure means that the heart muscle cannot pump blood strongly enough to supply all the blood needed throughout the body. Heart failure is not the same as heart attack and does not mean that the heart stops working.
Heart failure may start off with no symptoms, but as the condition progresses, patients may feel short of breath or may get tired easily after light physical activity such as walking. Some patients may wake up short of breath at night. Fluid may collect in different parts of the body, often first noticed as swollen ankles and feet.
Candesartan helps to treat heart failure and may improve your symptoms.
One of the ways candesartan helps heart failure is that it widens the blood vessels, so that the heart does not have to pump as hard to move the blood around the body. This also means that when you place extra demands on your heart, such as during exercise, the heart may cope better so you may not get short of breath as easily.
When used to treat heart failure, candesartan is almost always used with other medicines called diuretics or fluid tablets. These medicines help the kidney to get rid of excess fluid from the body.
Use in children
There is no information about its use in children, so candesartan is not recommended for children.

- If you become pregnant while you are using this medicine, tell your doctor.
- Tell all doctors, dentists and pharmacists who are treating you that you are using this medicine.
- If you are about to be started on any new medicine, tell your doctor or pharmacist that you are using this medicine.

Things to be careful of
Move slowly when getting out of bed or standing up if you feel faint, dizzy or light-headed.
Be careful driving or operating machinery until you know how candesartan affects you.
You may feel dizzy when you start taking candesartan.
If you are taking candesartan for high blood pressure, drink plenty of water during exercise and hot weather, especially if you sweat a lot. If you do not drink enough water while taking candesartan, you may faint or feel light-headed or sick. This is because your body doesn't have enough fluid and your blood pressure is low. If you continue to feel unwell, tell your doctor.
If you are taking candesartan for heart failure, restricted fluid intake is generally recommended. Speak with your doctor about how much water you should drink.
Please talk to your doctor or pharmacist about any concerns you may have about the above.
