Riluzole — Uses, Dosage, Side Effects & Safety

Drug class: Antineurodegenerative agent (Glutamate release inhibitor)

Overview

Riluzole is a medication used to treat amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. ALS is a progressive neurodegenerative disorder that affects nerve cells in the brain and spinal cord, leading to muscle weakness and loss of movement. Riluzole works by reducing the release of glutamate, a neurotransmitter that can be toxic to nerve cells in high amounts. By lowering glutamate levels, riluzole may help slow the progression of ALS and prolong survival, although it does not cure the disease or reverse existing damage. Patients should know that riluzole is most effective when started early in the course of ALS and should be taken regularly as prescribed. Routine blood tests are needed to monitor liver function during treatment.

Frequently Asked Questions about Riluzole

What is riluzole used for?

Riluzole is used to slow the progression of amyotrophic lateral sclerosis (ALS), helping to prolong survival and delay the need for ventilatory support.

How does riluzole work?

Riluzole works by inhibiting the release of glutamate, a neurotransmitter that can damage nerve cells when present in excess. This helps protect motor neurons in ALS.

What are the most common side effects of riluzole?

Common side effects include nausea, weakness, dizziness, decreased appetite, and numbness or tingling around the mouth.

Can riluzole cure ALS?

No, riluzole does not cure ALS. It may slow disease progression and extend survival but does not reverse existing nerve damage.

How should riluzole be taken?

Riluzole should be taken on an empty stomach, at least 1 hour before or 2 hours after meals, and at the same times each day.

What should I do if I miss a dose?

Take the missed dose as soon as you remember unless it is almost time for your next dose. Do not double up doses.

Are there any foods or drinks I should avoid while taking riluzole?

Avoid alcohol and limit caffeine intake, as both can affect riluzole metabolism and increase the risk of side effects.
