Pharmacist-reviewed drug information from the RxWiki encyclopedia.
Overview
Rilutek is a prescription medication used to slow the progress of Lou Gehrig's disease, known medically as amyotrophic lateral sclerosis (ALS). It is a disease of the central nervous system that affects the ability of a person to move certain muscles. Rilutek is not a cure, but may delay the need for a breathing tube (tracheostomy).
Rilutek belongs to a group of drugs called NMDA receptor antagonists. It works by decreasing glutamate, a natural substance in the body that can damage nerve cells.
This medication comes in tablet form. It is usually taken twice a day, every 12 hours, on an empty stomach.
Common side effects of Rilutek are weakness, nausea, and headache.

Quick facts
Avoid coffee, tea, cola, or other products that contain caffeine. Caffeine may cause too much riluzole to build up in your body.
When taking riluzole, avoid drinking excessive amounts of alcohol; alcohol may contribute to compromising liver function and may be associated with an increased risk of liver problems.
Tell your doctor if you use tobacco products. Cigarette smoking may decrease the effectiveness of this drug.
Riluzole tablets should be taken at least an hour before, or two hours after meals.
Riluzole does not cure ALS. It slows the progression of ALS. Continue taking riluzole even if you feel well.
