4. How do I use TRACLEER?
How much to take
Adults
The usual dose is one tablet, twice daily. For the first 4 weeks you will take a 62.5
mg tablet twice daily.
Depending on how you respond to the medicine, your doctor may increase the dosage
after four weeks to a 125 mg tablet twice daily.
Patients with low body weight
If you have body weight less than 40 kg but are over 12 years old, your doctor may
advise you to take a 62.5 mg tablet twice daily. The usual dose is one tablet, twice
daily.
Children aged 3 years and over
The dose will be determined by your doctor depending on the weight of the child.
Always take this medicine exactly as your doctor has instructed you. You should check
with your doctor or pharmacist if you are unsure.
When to take TRACLEER
TRACLEER is taken by mouth, in the morning and evening, and can be taken with or without
food.
Do not stop taking this medicine suddenly unless your doctor tells you to.
Stopping your treatment may lead to a worsening of your symptoms. Your doctor may
tell you to reduce the dose over a few days before stopping completely.
If you forget to use TRACLEER
TRACLEER should be used regularly at the same time each day. If you miss your dose
at the usual time, if there is still a long time to go before your next dose, take
it as soon as you remember and then go back to taking 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 you missed.
If you use too much TRACLEER
If you think that you have used too much TRACLEER, you may need urgent medical attention.
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.
5. What should I know while using TRACLEER?
Things you should do
Remind any doctor, dentist or pharmacist you visit that you are using TRACLEER.
Be sure to keep all your doctor’s appointments so your progress can be checked and
to monitor for side effects.
It is very important that you have a liver function blood test before you start treatment
and every month after that.
TRACLEER can cause liver damage if it is not found early. Because this side effect
may not cause symptoms at first, only a blood test can show that you have early liver
damage. Regular blood tests let your doctor change or stop your therapy before there
is permanent damage.
You should have a blood test for anaemia after 1 and 3 months, and then every 3 months
for the rest of your treatment.
You need to have pregnancy tests before you start treatment and monthly if you are
a female of childbearing age.
Driving or using machines
Be careful before you drive or use any machines or tools until you know how TRACLEER
affects you.
TRACLEER may cause dizziness, tiredness or blurred vision in some people.
Drinking alcohol
Tell your doctor if you drink alcohol.
We have no information on how alcohol affects TRACLEER.
