Medical Editor: John P. Cunha, DO, FACOEP
Robaxisal (methocarbamol and aspirin) is a combination of a muscle relaxant and a type of pain reliever called a salicylate, used together, along with rest and physical therapy, to treat injuries and other painful muscular conditions. The brand name Robaxisal is discontinued, but generic versions may be available. Common side effects of Robaxisal (methocarbamol and aspirin) include drowsiness, dizziness, lightheadedness, fainting, stomach upset, nausea, vomiting, diarrhea, metallic taste in the mouth, heartburn, blurred vision, headache, ringing in the ears, or colored urine (brown, black, or green color - this is not harmful).
The dose of Robaxisal for adults and children over 12 years of age is two tablets four times daily. Robaxisal may interact with antidepressants, alcohol, antihistamines, sedatives, other pain relievers, anxiety medicines, other muscle relaxants, anticoagulants, nonsteroidal anti-inflammatory drugs (NSAIDs), or other salicylates. Tell your doctor all medications and supplements you use. Aspirin is not recommended for use during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor. Do not use Robaxisal during the last 3 months of pregnancy because of possible harm to the fetus or problems during delivery. It is unknown if methocarbamol passes into breast milk. Aspirin passes into breast milk and may have undesirable effects on a nursing infant. Breastfeeding while using this drug is not recommended.
