Answer by Dr. Ru: About Chlorzoxazone usage in lactation

Centrally-acting muscle relaxant with sedative properties. Administered orally.It has pharmacokinetics with rapid absorption and elimination (PDR 2017, Prompila 2007, Desiraju 1983). Since the last update we have not found published data about its excretion in breast milk. Its pharmacokinetic data (low molecular weight, low protein binding, small volume of distribution) make its likely that it could pass into breast milk in quantities that could be significant. If you have to use it during breastfeeding, you should monitor sedative effects in the baby. To minimize exposure, medication can be taken just after a feed and waiting 3-4 hours before breastfeeding again.

Alternate Drugs for Muscle relaxants. ATC M03
