What ABISART HCT is used for
ABISART HCT is used to treat hypertension (i.e. high blood pressure). ABISART HCT is a trade name (manufacturer's name). ABISART HCT tablets contain two medicines, irbesartan and hydrochlorothiazide.
Your doctor measured your blood pressure and found it to be too high. Everyone has blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure) which means your blood pressure stays high even when you are calm and relaxed.
There are usually no symptoms of high blood pressure. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis. High blood pressure, if not treated, can damage blood vessels in several organs such as the heart, the kidneys, the brain and the eyes. This may lead to heart attacks, heart or kidney failure, strokes or blindness. There are usually no symptoms of high blood pressure before damage occurs, so your doctor needs to measure your blood pressure to see if it is too high.
High blood pressure can be treated and controlled with medicines such as ABISART HCT.
One of the active ingredients in ABISART HCT is irbesartan which belongs to a class of medicines called angiotensin-II receptor antagonists. Angiotensin II is a substance produced in the body which causes blood vessels to tighten.
Irbesartan blocks angiotensin-II and therefore relaxes your blood vessels. This helps to lower your blood pressure.
The other active ingredient in ABISART HCT is hydrochlorothiazide which belongs to a class of medicines known as diuretics. Diuretics cause an increase in the volume of urine. They also help with lowering blood pressure particularly when combined with other blood pressure reducing medicines.
Your doctor may also have recommended that you adjust your life style to help to lower your high blood pressure (losing weight, avoiding smoking, reducing alcohol consumption and restricting the amount of salt in the diet). Your doctor may also have encouraged the practice of regular, mild (not strenuous) exercise such as walking, swimming, etc.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
This medicine may affect your ability to drive a car or operate machinery.

How to take ABISART HCT
Follow all directions given to you by your doctor and pharmacist 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 much to take
ABISART HCT will usually be prescribed by your doctor if previous treatment does not produce a sufficient drop in your blood pressure. Your doctor will tell you how to switch from your previous treatment to ABISART HCT.
The usual dose of ABISART HCT is one tablet a day. The full blood pressure lowering effect should be reached 6-8 weeks after beginning treatment. If your blood pressure is not satisfactorily reduced with ABISART HCT, your doctor may prescribe another medicine to be taken with ABISART HCT.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How to take it
Swallow the tablets whole with a full glass of water.
When to take it
Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter whether you take ABISART HCT tablets before or after food.
How long to take it
This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
Therefore ABISART HCT must be taken every day.
Continue taking ABISART HCT until your doctor tells you to stop.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering 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 (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much ABISART HCT. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Symptoms of an overdose may include feeling lightheaded or dizzy.
While you are taking ABISART HCT
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking ABISART HCT.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
It may affect other medicines used during surgery.
If you become pregnant while taking this medicine, tell your doctor immediately.

It may interfere with the results of some tests.
Keep all of your doctor's appointments so that your progress can be checked.
Get up slowly when getting out of bed or standing up.
Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
Make sure you drink enough water during exercise and hot weather when you are taking ABISART HCT, especially if you sweat a lot.
If you do not drink enough water while taking ABISART HCT, you may faint or feel lightheaded or sick. This is because your body does not have enough fluid and your blood pressure is low. If you continue to feel unwell, tell your doctor.
If you have excessive vomiting and/ or diarrhea while taking ABISART HCT, tell your doctor.
This can also mean that you are losing too much water and your blood pressure may become too low.
Things you must not do
Do not take ABISART HCT to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change the dosage without checking with your doctor.
If you stop taking it suddenly, your condition may worsen.
Things to be careful of
Be careful driving or operating machinery until you know how ABISART HCT affects you.
As with many other medicines used to treat high blood pressure, ABISART HCT may cause dizziness or light-headedness in some people. Make sure you know how you react to ABISART HCT before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy or lightheaded.
Be careful when drinking alcohol while you are taking this medicine.
If you drink alcohol, dizziness or light-headedness may be worse.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
Hydrochlorothiazide contained in this medicine could produce a positive analytical result in antidoping test.
