1. What Riluzole is and what it is used for

What Riluzole is

The active substance in Riluzole 50 mg film-coated tablets is riluzole which acts on the nervous system.

What Riluzole is used for

Riluzole is used in patients with amyotrophic lateral sclerosis (ALS).

ALS is a form of motor neurone disease where damage to the nerve cells responsible for sending instructions to the muscles lead to weakness, muscle wastage and paralysis.

The destruction of nerve cells in motor neurone disease may be caused by too much glutamate (a chemical messenger) in the brain and spinal cord. Riluzole stops the release of glutamate and this may help in preventing the nerve cells being damaged.

Please consult your doctor for more information about ALS and the reason why this medicine has been prescribed for you.

2. What you need to know before you take Riluzole

Do not take Riluzole

  • if you are allergic to riluzole or any of the other ingredients of this medicine (listed in section 6)
  • if you have any liver disease or increased blood levels of some enzymes of the liver (transaminases)

Warnings and precautions

Talk to your doctor or pharmacist before taking Riluzole:

  • if you have any liver problems: yellowing of your skin or the whites of your eyes (jaundice), itching all over, feeling sick, being sick
  • if your kidneys are not working very well
  • if you have any fever (sometimes this can be due to a low number of white blood cells which can lead to an increased risk of infection).
