Consumer Medicine Information

What is in this leaflet

This leaflet answers to some common questions people ask about ADESAN HCT. It does not contain all the information that is known about ADESAN HCT.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor will have weighed the risks of you taking ADESAN HCT against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with this medicine. You may need to read it again.

What ADESAN HCT is used for

ADESAN HCT is used to treat high blood pressure.

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.

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

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

Your doctor may prescribe this medicine for another use. Ask your doctor if you want more information.

There is no evidence that ADESAN HCT is addictive.

How to take ADESAN HCT

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

If you do not understand the instructions on the label, 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 ADESAN HCT once a day, at about the same time each day. Keeping a regular time for taking ADESAN HCT will help to remind you to take it.

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

How long to take it

ADESAN HCT helps control your condition, but does not cure it. Therefore you must take ADESAN HCT 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 Australian Poisons Information Centre (telephone 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 ADESAN HCT even if there are no signs of discomfort or poisoning.

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

While you are using ADESAN HCT

Things you must do

Take ADESAN HCT 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 ADESAN HCT.

Tell your doctor if you have excessive vomiting or diarrhoea while taking ADESAN HCT. 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 ADESAN HCT.

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

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 ADESAN HCT.

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 ADESAN HCT 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 ADESAN HCT affects you. You may feel dizzy when you start taking ADESAN HCT due to the drop in your blood pressure.

Drink plenty of water while you are using ADESAN HCT, especially if you sweat a lot.

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

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

After taking it


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

Keep it in a cool, dry place and protect from light, where the temperature stays below 25°C.

Do not store it or any other medicine in the bathroom or near a sink. Do not leave it on window sills or in the car on hot days. 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 medicine you have left over if your doctor tells you to stop taking them, or you find that the expiry date has passed.
