Tobacco and Riluzole(Riluzole)
Tobacco smoking might speed the removal of Riluzole from the body, but it is not clear if tobacco smoking causes decreased effectiveness of Riluzole. Your prescriber will closely monitor your response to Riluzole treatment. If you plan to stop smoking, let your prescriber know, as the sudden cessation of smoking may result in increased levels of Riluzole, which might lead to side effects like nausea, diarrhea, dizziness, drowsiness, loss of appetite or weakness. Your prescriber will want to monitor your response to Riluzole treatment whenever a change in smoking status occurs.
Minor Lifestyle Interaction
Caffeine-containing Foods/Beverages and Riluzole 50mg Tablet(Riluzole)
