As part of the Food and Drug Administration’s (FDA) on-going initiative to ensure that all marketed U.S. drugs have required marketing approval, the agency announced today 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. Drugs containing trimethobenzamide in suppository form lack evidence of effectiveness. These products have been marketed under various names, including Tigan, Tebamide, T-Gen, Trimazide, and Trimethobenz.
