WHAT IRBESARTAN/HCT SANDOZ IS USED FOR
This medicine is used to lower high blood pressure, which doctors call hypertension.
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) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
There are often no symptoms of high blood pressure. The only way of knowing that you have high blood pressure is to have your blood pressure checked on a regular basis. If high blood pressure is not treated, it can damage blood vessels in several organs such as the heart, kidneys, brain and eyes. This may lead to serious health problems, such as blindness, stroke, heart disease and kidney failure.
High blood pressure can be treated and controlled with medicines such as Irbesartan/HCT Sandoz. Your doctor may also have recommended that you adjust your lifestyle 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.
This medicine contains the active ingredients irbesartan and hydrochlorothiazide. Both medicines reduce blood pressure in different ways.
Irbesartan belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin II is a substance produced in the body that causes blood vessels to narrow. Irbesartan blocks angiotensin-II and therefore relaxes your blood vessels. This helps to lower your blood pressure.
Hydrochlorothiazide belongs to the 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.
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.
There is no evidence that this medicine is addictive.

HOW TO TAKE IRBESARTAN/HCT SANDOZ
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, ask your doctor or pharmacist for help.
How much to take
Irbesartan/HCT Sandoz 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 Irbesartan/HCT Sandoz.
The usual dose of Irbesartan/HCT Sandoz 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 Irbesartan/HCT Sandoz, your doctor may prescribe another medicine to be taken with Irbesartan/HCT Sandoz.
Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.
Follow the instructions they give you. If you take the wrong dose, Irbesartan/HCT Sandoz may not work as well and your problem may not improve.
How to take it
The tablets should be taken regularly as directed by your doctor. The tablets should be swallowed whole with a full glass of water.
It does not matter whether you take the tablets before or after food.
When to take Irbesartan/HCT Sandoz
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.
How long to take Irbesartan/HCT Sandoz
Continue taking your medicine for as long as your doctor tells you.
This medicine helps to control your high blood pressure, but it does not cure it. Therefore Irbesartan/HCT Sandoz must be taken every day. Continue taking Irbesartan/HCT Sandoz until your doctor tells you to stop.
If you forget to take it
Take your dose as soon as you remember, and continue to take 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 take a double dose to make up for the dose that 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 Australia 13 11 26 or New Zealand 0800 POISON or 0800 764766) 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 Irbesartan/HCT Sandoz.

This may become worse if you stand up quickly as your blood pressure may fall. 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 you get dizzy or lightheaded talk to your doctor.
