What is Rilutek?

Rilutek is a prescription medication that is used to treat the nerve disease amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease). Rilutek contains riluzole and works by protecting the nerves in the brain and spinal cord from the natural substance glutamate. Rilutek can help to slow down the worsening of ALS but is not a cure.

Make sure to always read the patient information and instructions before using this medication. Always follow your doctor’s directions.

  • Take Rilutek on an empty stomach, either one hour before or two hours after a meal.
  • Rilutek is typically taken every 12 hours.
  • This medication is most effective when it is taken regularly. Try to take Rilutek at the same time every day.
  • Speak to your doctor if your condition worsens.


Tell your doctor and pharmacist:

  • About your drug and other allergies
  • If you take any other prescription or over-the-counter medications
  • Your medical history particularly of liver disease, kidney disease, or raised liver enzymes
  • If you are pregnant or planning pregnancy
  • If you are breast-feeding
  • If you smoke, start smoking or stop smoking. Smoking can affect the amount of this drug in your blood.
