Side effects

Some people complain of the following symptoms when using muscle relaxants:

  • blurred vision
  • drowsiness

These side effects usually go away as the body adjusts to the drug drug. Some also experience clumsiness or unsteadiness.


Because muscle relaxants work on the central nervous system, they may increase the effects of alcohol as well as other drugs that slow down the central nervous system.

The US Food and Drug Administration (FDA) does not recommend the long-term use of muscle relaxants.
