How to take this medicine

Follow all directions given to you by your doctor or pharmacist carefully.

They may differ from the information contained in this leaflet.

for help.

How much to take

This will depend on your condition and whether you are taking any other medicines.

Treatment is normally started in hospital with small doses of baclofen.

The dose is then gradually increased to an amount that works best for you.

For example, baclofen may be started at a dose of 15 mg a day, then increased slowly
to anywhere from 30 to 75 mg a day. Sometimes, doses up to 100 mg a day may be needed.

If you are under the age of 16 or over 65, or you have kidney disease, your doctor
may start you on a lower dose and increase it more gradually to prevent side effects.

How to take it

Swallow the tablets during meals with some water.

This will lessen the chance of a stomach upset.

Baclofen is usually taken in at least three divided doses throughout the day. But
your doctor may tell you to take it more or less often, depending on your situation.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.

Your doctor will check your progress to make sure the medicine is working and will
discuss with you how long your treatment should continue.

If you forget to take it

If it is almost time to take 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 then go back to taking your medicine
as you would normally.

Do not take a double dose to make up for missed doses.

This may increase the chance of you experiencing side effects.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some
hints to help you remember.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13
