Consumer Medicine Information (CMI)
This leaflet provides important information about taking Karvezide. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about taking Karvezide.
Where to find information in this leaflet:
1. Why am I taking Karvezide?
Karvezide 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 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.
Karvezide is used to treat high blood pressure, which doctors call hypertension.
2. What should I know before I take Karvezide?

4. How do I take Karvezide?
How much to take
Karvezide 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 Karvezide
The usual dose of Karvezide is one tablet once a day. The full blood pressure lowering
effect should be reached 6 to 8 weeks after beginning treatment.
If your blood pressure is not satisfactorily reduced with Karvezide, your doctor may
prescribe another medicine to be taken with Karvezide
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 provided and use Karvezide until your doctor tells you to
stop.
When to take Karvezide
Take Karvezide at about the same time each day.
How to take Karvezide
Swallow the tablet whole with a glass of water. It does not matter whether you take
Karvezide tablets before or after food.
Continue taking Karvezide until your doctor tells you to stop.
To help you remember to take your tablets each day, Karvezide 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" at the end of
the blister strip. 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 Karvezide
Karvezide should be used regularly at the same time each day.
If you miss your dose at the usual time and 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.
If you take too much Karvezide
If you think that you have used too much Karvezide, you may need urgent medical attention.
If you take too many Karvezide tablets you will probably feel light-headed or dizzy.
You should immediately:
phone the Poisons Information Centre
(by calling
13 11 26), or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.

taking Karvezide

dentist that you are taking Karvezide. Your blood pressure may drop suddenly
Make sure you drink enough water during exercise and hot weather when you are taking
Karvezide, especially if you sweat a lot. If you do not drink enough water while taking
Karvezide, 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.
Tell your doctor if you have excessive vomiting and/or diarrhoea while taking Karvezide.
You may lose too much water and salt and your blood pressure may drop too much.
Tell your doctor immediately if you feel light headed or dizzy after taking your first
dose of Karvezide, or when your dose is increased.

with symptoms of sunburn (such as redness, itching, swelling, blistering) occurring
more quickly than normal.
If you develop any shortness of breath or difficulty breathing after taking Karvezide,
seek medical attention immediately.
Tell your doctor if you experience abdominal pain, nausea, vomiting or diarrhoea after
taking Karvezide. Your doctor will decide on further treatment. Do not stop taking
Karvezide on your own.

as you

tells you to

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.

result in an antidoping test
