Full Consumer Medicine Information (CMI)
This leaflet provides important information about taking Karvea. 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 Karvea.
Where to find information in this leaflet:
1. Why am I taking Karvea?
Karvea contains the active ingredient irbesartan. Karvea is 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.
Karvea 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. Karvea also slows the decrease of kidney function in patients with high
blood pressure and type 2 diabetes.
Karvea is used to treat high blood pressure, which doctors call hypertension. Karvea
is also used in the treatment of kidney disease in patients with high blood pressure
and type 2 diabetes.
2. What should I know before I take Karvea?

4. How do I take Karvea?
How much to take
The usual starting dose is 150 mg tablet once a day. However, some patients may need
a lower starting dose. Your doctor will tell you if this is necessary. The full blood
pressure lowering effect of Karvea should be reached about 4 to 6 weeks after starting
treatment.
Depending on how your blood pressure responds, your daily dose of Karvea may need
to be increased. Most patients take either 150 mg or 300 mg once a day.
In patients with high blood pressure and type 2 diabetes, 300 mg once a day is the
preferred maintenance dose for slowing the progression of associated kidney disease.
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 take Karvea until your doctor tells you to stop.
When to take Karvea
Take Karvea at about the same time each day.
How to take Karvea
Swallow the tablet whole with a glass of water. It does not matter whether you take
Karvea tablets before or after food.
Continue taking Karvea until your doctor tells you to stop.
Karvea 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 Karvea
Karvea should be used regularly at the same time each day. If you miss your dose at
the usual time.
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 you missed.

you would normally.

5. What should I know while taking Karvea?
Things you should do

taking Karvea

is working

dentist that you are taking Karvea. Your blood pressure may drop suddenly
Make sure you drink enough water during exercise and hot weather when you are taking
Karvea, especially if you sweat a lot. If you do not drink enough water while taking
Karvea, you may faint or feel light-headed or sick. This is because your body does

tell your doctor.

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.

body get used to the change in position and blood pressure. If this problem continues
or gets worse, talk to your doctor.

Be careful before you drive or use any machines or tools until you know how Karvea
affects you.
As with many other medicines used to treat high blood pressure, Karvea may cause dizziness
or light- headedness in some people. If this occurs do not drive.
