Riluzole slows the progression of ALS. Avoid drinking large amounts of alcohol. Take this medication on an empty stomach.
Riluzole 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. Riluzole is not a cure but may delay the need for a breathing tube (tracheostomy).
Riluzole 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 riluzole are weakness, nausea, and headache.
