What ATACAND is used for

ATACAND is a type of medicine called an angiotensin II receptor antagonist (or blocker).

ATACAND is used to treat high blood pressure, also called hypertension.

ATACAND is also used to treat heart failure. It is used in combination with other medicines to treat your condition.

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.

ATACAND lowers blood pressure by dilating (expanding) small blood vessels from the heart, letting the blood be pumped around the body more easily.

Heart Failure:
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.

ATACAND helps to treat heart failure and may improve your symptoms.

One of the ways ATACAND 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, ATACAND is almost always used with other medicines called diuretics or fluid tablets. These medicines help the kidney get rid of excess fluid from the body.

Your doctor will have explained why you are being treated with ATACAND and told you what dose to take.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may prescribe this medicine for another reason.

ATACAND is not addictive.

Some medicines and ATACAND may interfere with each other. These include:

  • Any medicines containing potassium, including salt substitutes

These medicines may be affected by ATACAND or may affect the way ATACAND works. You may need different amounts of your medicines, or you may need to take different medicines.

It may be necessary to have regular blood tests done if you take any of these medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take ATACAND

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How to take it

The usual dose is one 8 mg tablet or one 16 mg tablet taken daily. Sometimes an increase in dose to 32 mg once daily is needed. Your doctor will tell you the dose of ATACAND you should take.

Take ATACAND once a day, at about the same time each day. Keeping a regular time for taking ATACAND will help to remind you to take it.

It does not matter whether you take ATACAND with food or on an empty stomach.

How long to take it

Continue taking this medicine for as long as your doctor tells you.

This medicine controls your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

If you forget to take it

If you forget to take a dose, take it as soon as you remember, as long as it is at least 12 hours before your next dose is due. Then go back to taking it as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do NOT double the dose.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (13 11 26) or go to Accident and Emergency at your nearest hospital immediately if you think that you or anyone else may have taken too much ATACAND, even if there are no signs of discomfort or poisoning.

If you take too many ATACAND you may get a headache, feel sick (nausea), dizzy and very tired.

While you are using ATACAND

Things you must do

Take ATACAND exactly as your doctor has told you to. Your blood pressure will not be well controlled if you do not.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking ATACAND.

Tell all doctors, dentists and pharmacists who are treating you that you are taking ATACAND.

Tell your doctor immediately if you become pregnant or plan to become pregnant while you are taking ATACAND. You should not use ATACAND if you are pregnant or thinking about becoming pregnant. Your doctor can discuss different treatment options with you.

If you plan to have surgery (even at the dentist) that needs a general anaesthetic, tell your doctor or dentist that you are taking ATACAND.

Be sure to keep all of your doctor’s appointments so that your progress can be checked. Your doctor will check your progress and may want to take some tests (e.g. blood tests, blood pressure) from time to time. These tests may help to prevent side effects.

Things you must not do

Do not use it to treat any other complaints unless your doctor says to.

Do not give this medicine to anyone else, even if they have the same condition as you.

Do not stop taking ATACAND unless you have discussed it with your doctor.

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 ATACAND affects you. You may feel dizzy when you start taking ATACAND.

If you are taking ATACAND 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 ATACAND, 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 ATACAND 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 these possibilities if you think they may bother you.

After using ATACAND


Keep your tablets in the blister pack until it is time to take them. If you take ATACAND out of the blister pack it will not keep well.

Keep it in a cool, dry place where the temperature stays below 30°C.

Do not store it or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.

Keep it where young children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking them, or the tablets have passed their expiry date, ask your pharmacist what to do with any ATACAND tablets you have left over.
