Dextromethorphan Abuse "Not Gaining Popularity," Whitehall-Robins Says

Misuse of the cough suppressant dextromethorphan hydrobromide is "limited and episodic" and is "not gaining popularity," Whitehall-Robins tells FDA in a Jan. 19 submission. The firm's letter and attached materials relate to a MedWatch adverse event report detailing the Oct. 13 death of a 23-year-old man who "committed suicide by hanging after probably having ingested a DM-containing product."
