Action: How Atacand Plus works

Candesartan cilexetil is a type of medicine called an angiotensin II receptor antagonist (or blocker). It mainly works by causing relaxation of blood vessels.

Hydrochlorothiazide is a type of medicine called a diuretic. It works by reducing the amount of excess fluid in the body.

Using these two medicines together will lower your blood pressure more than using either one on its own.

Atacand Plus is available in three different tablet strengths:

  • Atacand Plus 16/12.5. Each Atacand Plus 16/12.5 tablet contains candesartan cilexetil 16 mg and hydrochlorothiazide 12.5 mg as the active ingredients;
  • Atacand Plus 32/12.5. Each Atacand Plus 32/12.5 tablet contains candesartan cilexetil 32 mg and hydrochlorothiazide 12.5 mg as the active ingredients; and
  • Atacand Plus 32/25. Each Atacand Plus 32/25 tablet contains candesartan cilexetil 32 mg and hydrochlorothiazide 25 mg as the active ingredients.

Atacand Plus also contains the inactive ingredients carmellose calcium, hyprolose,  iron oxide red (E 172), iron oxide yellow (E 172), lactose monohydrate, magnesium stearate (E 572), maize starch, macrogol.

How to take Atacand Plus

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained here.

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 tablet once daily, taken whole with a glass of water.

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

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

How long to take it

Atacand Plus helps control your condition but does not cure it. Therefore you must take Atacand Plus every day. Continue taking the tablets for as long as your doctor tells you to.

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 less than 12 hours to 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 Plus, even if there are no signs of discomfort or poisoning.

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

While you are using Atacand Plus

Things you must do

Take Atacand Plus 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 Plus.

Tell your doctor if you have excessive vomiting or diarrhoea while taking Atacand Plus. You may lose too much water and your blood pressure may become too low.

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

Tell your doctor immediately if you become pregnant or plan to become pregnant while you are taking Atacand Plus. You should not use Atacand Plus 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 Plus.

Tell your doctor if you plan to have an examination such as an X-ray or a scan requiring an injection of iodinated contrast (dye) that you are taking Atacand Plus.

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 symptoms that seem similar to yours.

Do not stop taking Atacand Plus 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 Plus affects you. You may feel dizzy when you start taking Atacand Plus due to the drop in your blood pressure.

Drink plenty of water while you are using Atacand Plus, especially if you sweat a lot.

Please talk to your doctor or pharmacist about these possibilities if you think they may bother you.

After using Atacand Plus


Keep your tablets in the blister pack until it is time to take them. If you take Atacand Plus 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 windowsill 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.


Ask your pharmacist what to do with any Atacand Plus tablets you have left over if your doctor tells you to stop taking them, or you find that the expiry date has passed.
