Trimethobenzamide hydrochloride suppositories

Audience: Healthcare professionals, consumers

[Posted 04/06/2007] FDA notified healthcare professionals and consumers that companies must stop manufacturing and distributing unapproved suppository drug products containing trimethobenzamide hydrochloride. These products are used to treat nausea and vomiting in adults and children. The products have been marketed under various names, including Tigan, Tebamide, T-Gen, Trimazide, and Trimethobenz. Drugs containing trimethobenzamide in suppository form lack evidence of effectiveness. This action does not affect oral capsules and injectable products containing trimethobenzamide that have been approved by FDA. FDA urges consumers currently using trimethobenzamide suppositories or who have questions or concerns to contact their healthcare professional. Alternative products approved to effectively treat nausea and vomiting are available in a variety of forms.
