Table of contents:

Rilutek (generically known as riluzole) is a medication used to treat amyotrophic lateral sclerosis (ALS), a progressive neurological disease that affects nerve cells in the brain and spinal cord. Riluzole is in a class of medications called benzothiazoles. It works by reducing the levels of a neurotransmitter called glutamate in the brain, which is believed to contribute to the death of nerve cells in ALS.

Uses and Dosage

Rilutek is available as a capsule-shaped, white, film-coated tablet for oral administration containing 50 mg of riluzole and should take Riluzole tablets by mouth. It is usually taken twice a day, every 12 hours, and should be taken at the same times each day, usually in the morning and evening. The recommended dosage of Rilutek for ALS is 50 mg twice daily, taken at least one hour before or two hours after a meal.

For the best results, take it on an empty stomach, 1 hour before or 2 hours after meals. Follow the instructions on the prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. Take Riluzole exactly as directed, and do not take more or less than prescribed, or take it more often than directed by your doctor.
