Muscle Relaxants and Alcohol Interactions

Written on Nov 7, 2017 by L. Anderson, PharmD

Skeletal muscle relaxants are a varied group of medications commonly used to treat two different types of conditions:

  • Spasticity from upper motor neuron syndromes
  • Spasms from painful muscle conditions.

Spasticity, pain, and stiffness may occur in cerebral palsy, multiple sclerosis, traumatic brain injury, or with stroke. Muscles spasms are usually short-lived and linked with conditions like low back pain, tension headaches, or fibromyalgia. These agents work in the central nervous system and block pain sensations between the nerves and the brain. Some agents come combined with an antiinflammatory.

Alcohol should be avoided if you are under treatment with a muscle relaxant.

  • Most of these drugs can lead to additional central nervous system depression when consumed with alcohol.
  • Side effects such as dizziness, drowsiness, confusion, weakness and problems with judgement or thinking can occur. Avoid hazardous activities such as driving or operating dangerous machinery.
  • Carisoprodol is metabolized to meprobamate and can lead to an opiate-like effect when combined with alcohol.
  • To review specific muscle relaxant interactions with alcohol, visit the Drugs.com Drug Interaction Checker and speak with your pharmacist or doctor.
