Rilutek (Riluzole) is used to treat a certain type of nerve disease called amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease. It is designed to slow down the worsening of this disease and prolong survival.

Riluzole works by preventing nerve cell overactivation, thereby slowing the progression of ALS and the accumulation of symptoms. It has been shown in clinical trials to delay the need for ventilatory support and extend survival in people with ALS. However, it generally cannot reverse symptoms that have already occurred.


  • Take Rilutek exactly as prescribed by your healthcare provider, typically twice a day on an empty stomach (at least 1 hour before or 2 hours after a meal).
  • If using the liquid form, shake the bottle well for 30 seconds before measuring your dose.
  • Use the provided measuring spoon or device for accurate dosing (not a household spoon).
  • Take Rilutek consistently at the same times each day for the best results.


  • Don't take more Rilutek than prescribed by your healthcare provider. Increasing the dose won't improve your condition faster and might lead to side effects.
  • Don't take Rilutek with food. It needs to be taken on an empty stomach for proper absorption.
  • Don't use a household spoon to measure the liquid medication.
  • Don't stop taking Rilutek without consulting your healthcare provider, even if you feel well.

Inform your healthcare provider about any allergies you have, especially to riluzole or any ingredients in the medication.

Riluzole may cause dizziness or drowsiness. Avoid driving, operating machinery, or activities requiring alertness until you know how it affects you. Limit alcohol and discuss marijuana use with your healthcare provider as they can worsen these effects.

If you have diabetes, phenylketonuria (PKU), or any condition requiring you to limit sugar or aspartame intake, talk to your healthcare provider about using riluzole (especially liquid forms).

Before any surgery, inform your healthcare provider about all medications you use, including riluzole.

Riluzole may harm an unborn baby. Discuss risks and benefits with your healthcare provider before using it if you are pregnant. It is unknown if riluzole passes into breast milk. Consult your healthcare provider before breastfeeding.
