Overview

Rilutek 50mg Tablet is a prescription-only medicine (POM) presented as a tablet, with Riluzole 50mg as its active ingredient content.

This page is limited to product, safety and handling information, in line with Malaysian rules on prescription medicine information for the public. Your prescriber or pharmacist is the right source for anything beyond that, together with the leaflet inside the pack.

Through DoctorOnCall, this product is supplied after an online consultation with a licensed doctor and a valid prescription, and it is checked by a registered pharmacist before dispensing. Take it exactly as prescribed, and speak to your doctor before stopping, changing the dose, or starting any other medicine alongside it.

Directions for Use

Take Rilutek 50mg Tablet at the same times each day, one hour before or two hours after a meal, as food reduces the amount of riluzole absorbed. Swallow the tablet whole with water. Continue taking it as prescribed, and do not stop or change the dose without discussing it with your specialist first.

Dosage

The usual dose of Rilutek 50mg Tablet is 50mg taken twice daily, spaced 12 hours apart. Your specialist will monitor your liver function regularly, particularly during the first months of treatment, and will advise on any dose adjustment based on how you tolerate the medicine.

Storage Instructions

Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Side Effects

  • Nausea
  • Dizziness
  • Headache
  • Fatigue or weakness
  • Increased liver enzyme levels
  • Loss of appetite
  • Cough or breathing difficulty

Contraindications

  • Known hypersensitivity to riluzole or any ingredient in this product
  • Liver disease or liver enzyme levels significantly above normal
  • Pregnancy and breastfeeding, unless clearly advised by your specialist

Drug / Food Interactions

  • Food reduces the absorption of riluzole – take on an empty stomach as directed
  • Other medicines metabolised by the liver (e.g. theophylline) may interact, requiring dose review
  • Cigarette smoking can reduce riluzole blood levels by increasing its breakdown in the liver
  • Combining with other medicines that affect liver enzymes may require closer monitoring

Quick Tips

  • Take on an empty stomach, one hour before or two hours after meals, at consistent times each day
  • Attend all scheduled liver function blood tests, especially in the first few months of treatment
  • Understand that riluzole is intended to slow disease progression and extend survival, not to reverse existing muscle weakness
  • Report new fever, unusual tiredness, or yellowing of the skin/eyes to your specialist promptly
  • Continue all other supportive ALS care (physiotherapy, respiratory and nutritional support) alongside this medicine
