What Clofen is used for

Clofen is used to control muscle spasms in conditions such as:

  • multiple sclerosis
  • spinal cord damage resulting from disease or physical injury.

Clofen belongs to a group of medicine called muscle relaxants.

This medicine works by reducing excess muscle tension, thereby reducing pain and stiffness. This can help improve mobility and the management of daily activities.

Clofen may be used alone, or in combination with other medicines, to treat your condition.

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.

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 box/bottle, ask your doctor or pharmacist for help.

How much to take

Treatment with Clofen is usually started in hospital using low doses.

The dose varies from person to person.

The usual starting dose is 5 mg three times a day (15 mg per day).

Your doctor may increase this dose slowly depending on how you respond to Clofen. Doses can range from 30 mg to 75 mg per day. The maximum dose is 100 mg per day.

Your doctor will tell you how many tablets you need to take each day and when to take them.

People over 65 or below 16 years of age and those with kidney problems may need smaller doses.

How to take it

Swallow the tablets with a glass of water.

When to take it

Take Clofen during meals. This will lessen the chance of a stomach upset.

Clofen is usually taken as 3 divided doses throughout the day. However, your doctor may advise you differently depending on your situation.

How long to take it

Keep taking Clofen for as long as your doctor recommends. Your doctor will discuss with you how long treatment with Clofen should continue for, especially if you do not respond after 6 to 8 weeks of treatment at the maximum dosage.

Do not stop taking Clofen suddenly, even if you feel better after a few days, unless advised by your doctor.

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 the missed dose as soon as you remember, and then 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 are not sure what to do or have any questions, ask your doctor or pharmacist for help.

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. You may need urgent medical attention.

If you take too much Clofen, you may feel drowsy, have problems breathing or lose consciousness.

You may also feel confused, hallucinate, have blurred vision, feel sick (nausea), vomit, faint, have diarrhoea, increased saliva, a slow or irregular heart beat, muscle weakness or seizures (fits).

While you are taking Clofen

Things you must do

If you become pregnant while taking Clofen, tell your doctor immediately.

Before starting any new medicine, tell your doctor or pharmacist that you are taking Clofen.

Tell all the doctors, dentists and pharmacists who are treating you that you are taking Clofen.

If you plan to have surgery that needs a general anaesthetic, including dental surgery, tell your doctor or dentist that you are taking Clofen.

Visit your doctor regularly so they can check on your progress. Your doctor may order some blood tests to prevent unwanted side effects, especially for people with liver problems or diabetes.

Things you must not do

Do not stop taking Clofen, or change the dose, without checking with your doctor. Do not let yourself run out of your medicine over weekends or during holidays. Stopping Clofen suddenly may cause unwanted effects such as mood changes or mental disturbances, seizures (fits), a fast heart beat and worsening of muscle spasms.

Your doctor will tell you how to gradually reduce the amount of Clofen you are taking before stopping completely. This may take a few weeks.

Do not use Clofen to treat any other conditions unless your doctor tells you to.

Do not give Clofen to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how Clofen affects you. Clofen may cause drowsiness, especially at the start of treatment, dizziness or lightheadedness in some people. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.

Be careful when drinking alcohol while taking Clofen. Combining Clofen and alcohol can make you feel more sleepy, dizzy or lightheaded. Your doctor may suggest you avoid alcohol while you are taking Clofen.

Be careful taking other medicines that can cause drowsiness while you are taking Clofen. Combining Clofen with medicines that can cause sedation (make you sleepy) can make you more drowsy or dizzy. Your doctor and pharmacist can give you more information.

Side effects to Clofen are usually short-lived and mainly occur at the start of treatment or if the dose of Clofen is too high or increased too quickly.

Do not suddenly stop taking Clofen. If unwanted side effects do occur, tell your doctor. Your doctor may lower the dose to relieve any side effects.

If you are over 65 years of age or have brain blood vessel problems (eg. stroke) or a history of mental disorders, the chance of side effects may be increased.

After taking Clofen


Keep Clofen where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Keep your tablets in the bottle until it is time to take them. If you take the tablets out of the bottle they may not keep well.

Keep your tablets in a cool dry place where the temperature stays below 25°C.

Do not store Clofen or any other medicine in the bathroom or near a sink.

Do not leave Clofen in the car or on window sills. Heat and dampness can destroy some medicines.


If your doctor tells you to stop taking Clofen, or your tablets have passed their expiry date, ask your pharmacist what to do with any that are left over.
