What is in this leaflet

This leaflet answers some common questions about CLOFEN.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking CLOFEN against the benefits expected for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.

What CLOFEN is used for

CLOFEN belongs to a group of medicines called muscle relaxants.
This medicine is used to reduce stiffness and/or spasms in your muscles.
CLOFEN is used to control muscle spasms in conditions such as:
multiple sclerosis
spinal cord damage resulting from disease or physical injury
Because this medicine reduces spasms and the pain that goes with them, it helps to make you moremobile and better able to manage your daily activities.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
CLOFEN is only available with a doctor’s prescription.

How to take CLOFEN

Follow all directions given to you by your doctor and pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the bottle, ask your doctor or pharmacist for help.

How much to take

Treatment is usually started in hospital with small doses of CLOFEN. The dose is then gradually increased to an amount that works best for you. For example, CLOFEN may be started at a dose of 15 mg per 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 unwanted side effects.

How to take it

Swallow the tablets during meals with a little liquid.
CLOFEN is usually taken in at least 3 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

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 for you and will discuss with you how long your treatment should continue.

If you forget to take it

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 then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much CLOFEN.
Do this even if there are no signs of discomfort or poisoning.
The main symptoms of overdose are: drowsiness, breathing difficulties, consciousness disorders and being unconscious (coma).
Other symptoms may include: feeling confused, hallucinations, agitation, convulsions, blurred vision, unusual muscle slackness, sudden contraction of the muscles, poor or absent reflexes, high or low blood pressure, slow, fast or irregular heartbeat, low body temperature, nausea, vomiting, diarrhoea, or excessive salivation, trouble breathing during sleep (sleep apnoea), pain in your muscles, fever and dark urine (rhabdomyolysis).
If you have kidney disease and have accidently taken more tablets than your doctor has prescribed, you may experience some neurological symptoms of overdose such as drowsiness, feeling confused or hallucinations.

While you are taking CLOFEN

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking CLOFEN.
Tell any other doctors, dentists and pharmacists who treat you that you are taking CLOFEN.
If you become pregnant while taking CLOFEN, tell your doctor immediately.
Your doctor can discuss with you the risks of taking it while you are pregnant.
Be sure to keep all of your doctor’s appointments so that your progress can be checked.
To help prevent unwanted side effects from happening, your doctor may want to do some tests from time to time during the course of your treatment.
If your muscle spasms come back, tell your doctor.
Your doctor may be able to change the dose of CLOFEN to make it work better for you.

Things you must not do

Do not stop taking CLOFEN suddenly.
This medicine is not habit-forming but stopping it suddenly may bring on severe spasms and other unwanted symptoms, such as nervousness, feeling confused, hallucinations, abnormal thinking or behaviour, convulsions, uncontrollable twitching, jerking or writhing movements, fast heartbeat, high body temperature, pain in muscles, fever and dark urine. The excessive stiffness (spasms) in your muscles may also get worse.
If CLOFEN must be stopped, your doctor will reduce the dose gradually over a period of 1 to 2 weeks so that these unwanted effects are avoided.
Do not take CLOFEN to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if their symptoms seem to be similar to yours.

Things to be careful of

Be careful driving, operating machinery or doing other jobs that require you to be alert while you are taking CLOFEN until you know how it affects you.
This medicine may cause sleepiness and decreased alertness in some people, especially at the start of treatment.
Be careful when drinking alcohol while taking CLOFEN.
The combination may make you feel more sleepy and less alert than usual.
