Drug Levels and Effects

Summary of Use during Lactation

Clotiazepam is not approved for marketing in the United States by the U.S. Food and Drug Administration. Very little information is available on the passage of clotiazepam into milk. One review recommends avoiding clotiazepam during breastfeeding.[1] An alternate drug is preferred, especially while nursing a newborn or preterm infant.

Drug Levels

Maternal Levels. A woman who was taking oral clotiazepam 5 mg daily donated a milk sample between 3 and 6 days postpartum at 1 hour after a dose at the estimated peak serum concentration. She had a 1-hour milk level of 16.3 mcg/L.[2]

Infant Levels. Relevant published information was not found as of the revision date.
