Alcohol and Methocarbamol, a caution.
Methocarbamol can cause sedation, dizziness, and impaired coordination, and alcohol can make these effects stronger. The combination can lead to unsafe driving, falls, confusion, and excessive sleepiness. Risk rises when methocarbamol is taken with opioids, benzodiazepines, sleep medicines, or other sedatives.

Caution
What is happening. Methocarbamol can cause sedation, dizziness, and impaired coordination, and alcohol can make these effects stronger. The combination can lead to unsafe driving, falls, confusion, and excessive sleepiness. Risk rises when methocarbamol is taken with opioids, benzodiazepines, sleep medicines, or other sedatives.
Mechanism. Methocarbamol is a centrally acting skeletal muscle relaxant whose benefit and adverse effects are largely mediated through central nervous system depression. Alcohol adds independent sedating and psychomotor-impairing effects, increasing the total depressant burden.
Recommendation. Avoid alcohol while taking methocarbamol. If you accidentally combine them, avoid driving and do not take additional sedatives. Get medical help for severe confusion, fainting, or breathing problems.
