What is Irbesatzide GH used for
Irbesatzide GH is used to lower high blood pressure, which doctors call hypertension.
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 lead to serious health problems, such as stroke, heart disease and kidney failure.
How Irbesatzide GH works
Irbesatzide GH contains 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 widens your blood vessels, making it easier for your heart to pump blood throughout your body. 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.
Your doctor may have prescribed Irbesatzide GH for another reason.
Ask your doctor if you have any questions about why Irbesatzide GH has been prescribed for you. This medicine is only available with a doctor's prescription.
There is no evidence that this medicine is addictive.

How to take Irbesatzide GH
How much to take
Irbesatzide GH 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 Irbesatzide GH.
The usual dose of Irbesatzide GH 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 Irbesatzide GH, your doctor may prescribe another medicine to be taken with Irbesatzide GH.
How to take it
Swallow the tablet whole with a glass of water.
It does not matter whether you take Irbesatzide GH tablets before or after food.
When to take it
Take Irbesatzide GH at about the same time each day.
Taking your tablets at the same time each day will have the best effect. It will also help you remember when to take the tablets.
How long to take it
Continue taking Irbesatzide GH until your doctor tells you to stop.
Irbesatzide GH helps control your high blood pressure but does not cure it.
Therefore Irbesatzide GH must be taken every day.
To help you remember to take your tablets each day, Irbesatzide GH tablets are supplied in a calendar pack with the foil backing marked with the days of the week. This is just a way to help you to remember to take your tablets. All of the tablets in the pack are the same.
When you start a new strip of tablets, take the tablet marked "START". On the next day, take the tablet marked with the relevant day of the week.
Continue taking your tablets each day until all of the tablets are taken. Commence the next strip at "START" and continue as before.
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 go back to taking your tablets 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 any unwanted side effects.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone: 13 11 26) or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Irbesatzide GH.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too many Irbesatzide GH tablets, you will probably feel light-headed or dizzy.
While you are using Irbesatzide GH
Things you must do
Tell any other doctors, dentists and pharmacists who are treating you that you are taking Irbesatzide GH.
If you become pregnant while taking Irbesatzide GH tell your doctor immediately.
Have your blood pressure checked when your doctor tells you to, to make sure Irbesatzide GH is working.
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking Irbesatzide GH.
If you plan to have surgery or other treatment (even at the dentist) that needs an anaesthetic, make sure that you tell your doctor or dentist that you are taking Irbesatzide GH.
Your blood pressure may drop suddenly.
Make sure you drink enough water during exercise and hot weather when you are taking Irbesatzide GH, especially if you sweat a lot.
If you do not drink enough water while taking Irbesatzide GH, you may faint or feel light-headed 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 diarrhoea while taking Irbesatzide GH, tell your doctor.
You may lose too much water and salt and your blood pressure may drop too much.
If you feel light-headed or dizzy after taking your first dose of Irbesatzide GH, or when your dose is increased, tell your doctor immediately.
Things you must not do
Do not give Irbesatzide GH tablets to anyone else, even if they have the same condition as you.
Do not take Irbesatzide GH to treat any other complaints unless your doctor or pharmacist tells you to.
Do not stop taking Irbesatzide GH, or lower the dosage, without checking with your doctor.
Things to be careful of
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
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.
Be careful driving or operating machinery until you know how Irbesatzide GH affects you. As with many other medicines used to treat high blood pressure, Irbesatzide GH may cause dizziness or light-headedness in some people. If this occurs do not drive.
Make sure you know how you react to Irbesatzide GH before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy or light-headed.
If you drink alcohol, dizziness or light-headedness may be worse.
The hydrochlorothiazide contained in this medicine could produce a positive analytical result in an antidoping test.
Things that would be helpful for lowering your blood pressure
Some self help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.
- Alcohol - your doctor may advise you to limit your alcohol intake.
- Weight - if you are overweight, your doctor may suggest losing some weight to help lower your blood pressure and help lessen the amount of work your heart has to do. Some people may need a dietician's help to lose weight.
- Diet - your doctor may advise you to eat a healthy low-fat diet which includes plenty of fresh vegetables, fruit, bread, cereals and fish.
- Salt - your doctor may advise you to watch the amount of salt in your diet. To reduce your salt intake you should avoid using salt in cooking or at the table.
- Exercise - regular exercise helps to reduce blood pressure and helps get the heart fitter, but it is important not to overdo it. Walking is good exercise, but try to find a route that is reasonably flat. Before starting any exercise, ask your doctor about the best kind of program for you.
- Smoking - your doctor may advise you to stop smoking or at least cut down.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Irbesatzide GH.
Irbesatzide GH helps most people with high blood pressure, but it may have unwanted side effects in a few people. 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.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
- dizziness or light-headedness (vertigo),
- unusual tiredness or weakness,
- pain in the stomach or gut,
- nausea and/or vomiting,
- sexual problems.
These are generally mild and do not normally require treatment to be interrupted.
Tell your doctor immediately if you notice any of the following:
- skin rash or itchiness,
- aching muscles or sore joints, not caused by exercise,
- muscle pain or weakness,
- buzzing, ringing or other persistent noise in the ears,
- changes in heart rhythm,
- you are not urinating (passing water) as much as normal,
- numbness or tingling in fingers or toes,
- painful, swollen joints that may be symptoms of gout,
- yellowing of the skin and/or eyes, also known as jaundice,
- symptoms that may occur if you have developed diabetes, such as excessive thirst, passing greatly increased amounts of urine, increased appetite with weight loss, feeling tired, drowsy, weak, depressed, irritable and generally unwell,
- symptoms that may indicate kidney disease such as passing little or no urine, drowsiness, nausea, vomiting, breathlessness, loss of appetite and weakness,
- symptoms that may indicate high potassium levels in the blood such as nausea, diarrhoea, muscle weakness and changes in heart rhythm,
- symptoms that may indicate liver disease such as nausea, vomiting, loss of appetite, feeling generally unwell, fever, itching, yellowing of the skin and eyes and dark coloured urine.
These are serious side effects. Skin rash and itchiness may be symptoms of an allergic reaction.
You may need medical attention. These side effects are not common.
If any of the following happen, stop taking Irbesatzide GH and either tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
- swelling to the face, lips, tongue or throat, which may cause difficulty in swallowing or breathing;
- severe and a sudden onset of pinkish, itchy swellings on the skin, also called hives or nettlerash.
These are very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.
Other side effects not listed above may occur in some patients. Tell your doctor or pharmacist if you notice anything that is making you feel unwell.
After using Irbesatzide GH
Keep your Irbesatzide GH tablets in the blister pack until it is time to take them.
If you take the tablets out of the blister pack they will not keep well.

Heat and dampness can destroy some medicines.
Keep all medicines out of the reach of children.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
