What is AVAPRO HCT
AVAPRO HCT is a trade name (manufacturer's name). AVAPRO HCT tablets contain two medicines, irbesartan and hydrochlorothiazide.
Both these medicines are in the tablets your doctor has prescribed for you.
What AVAPRO HCT is used for
AVAPRO HCT lowers 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) 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 AVAPRO HCT. 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.
What AVAPRO HCT does and how it works
AVAPRO HCT 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 which causes blood vessels to tighten. 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.
Your doctor may have prescribed AVAPRO HCT for another use. If you want more information, ask your doctor.

Your doctor will decide whether your treatment needs to be altered or whether you should have check ups more frequently.
How to take AVAPRO HCT
The tablets should be taken regularly as directed by your doctor. The tablets should be swallowed with a drink of water.
How much to take:
AVAPRO 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 AVAPRO HCT.
The usual dose of AVAPRO 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 AVAPRO HCT, your doctor may prescribe another
medicine to be taken with AVAPRO HCT.
Follow all directions given to you by your doctor 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.
When to take it:
You should always take your daily dose of AVAPRO HCT at about the same time each day. Taking your AVAPRO HCT tablets at the
same time each day will have the best effect.
It does not matter whether you take AVAPRO HCT tablets before or after food.
How long to take it:
AVAPRO HCT helps to control your high blood pressure, but does not cure it. Therefore AVAPRO HCT must be taken every day.
Continue taking AVAPRO HCT until your doctor tells you to stop.
If you miss a dose:
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.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.
Do not take a double dose to make up for the missed dose.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you take too much AVAPRO HCT (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone: 131126) or go to the Accident and Emergency Department
at your nearest hospital, if you or anyone else may have taken too much AVAPRO HCT.
Do this even if there are no signs of discomfort or poisoning.
If you take too many AVAPRO HCT tablets, you will probably feel lightheaded or dizzy.
While you are using AVAPRO HCT
Things you must do:
If you become pregnant while taking AVAPRO HCT tell your doctor immediately.
Have your blood pressure checked when your doctor tells you to, to make sure AVAPRO HCT is working.
If you are about to start on any new medicine, tell your doctor and pharmacist that you are taking AVAPRO HCT.
Get up slowly when getting out of bed or standing up.
You may feel light-headed or dizzy while taking AVAPRO HCT. 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 light-headed talk to your doctor.
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 AVAPRO HCT
Make sure you drink enough water during exercise and hot weather when you are taking AVAPRO HCT, especially if you sweat a
If you do not drink enough water while taking AVAPRO HCT, 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 AVAPRO 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 give AVAPRO HCT tablets to anyone else, even if they have the same condition as you.
Things to be careful of:
Be careful driving or operating machinery until you know how AVAPRO HCT affects you. As with many other medicines used to
treat high blood pressure, AVAPRO HCT may cause dizziness or light-headedness in some people. Make sure you know how you
react to AVAPRO HCT before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy
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.
AVAPRO HCT 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.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking AVAPRO HCT.
Tell your doctor if you notice any of the following and they worry you -
dizziness or light-headedness (vertigo)
unusual tiredness or weakness, fatigue
pain in the stomach or gut; nausea and/or vomiting
These are generally mild and do not normally require treatment to be interrupted.

skin rash or itchiness
aching muscles or aching joints, not caused by exercise
muscle pain, weakness or paralysis of muscles
buzzing, ringing or other persistent noise in the ears
changes in heart rhythm

painful, swollen joints which 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
disturbances in your vision (such as blurred vision and seeing haloes around lights) and eye pain
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 AVAPRO HCT and tell your doctor immediately or go to casualty at your nearest
swelling to the face, lips, tongue or throat, which may cause difficulty in swallowing or breathing. If you have them, you
may have a serious allergic reaction to AVAPRO HCT
severe and sudden onset of pinkish, itchy swellings on the skin, also called hives or nettle rash. If you have them, you may
have a serious allergic reaction to AVAPRO HCT
symptoms that may indicate liver disease with 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. 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. If you notice any other unwanted effects, you should tell
your doctor or pharmacist and ask for their advice.
After using AVAPRO HCT
Keep your AVAPRO HCT tablets in the blister pack until it is time to take them.
