Warnings

Skelaxin may enhance the effects of alcohol and other CNS depressants. It may impair mental and/or physical abilities required for performing hazardous tasks, such as operating machinery or driving a motor vehicle, especially when used with alcohol or other CNS depressants.

Serotonin syndrome is a rare but serious and potentially fatal complication caused by Skelaxin overdose, or by taking multiple drugs together that all affect your body's serotonin level. A number of drugs, including tramadol, have been known to cause this effect when taken with metaxalone.
