Hello, I'm trying to code a overdose of Trazodone Hydrochloride, but this particular drug is not listed in the drug and chemical table where I can access the poisoning number and proper E-code. The ICD-9 book does speak of an American Hospital Formulary Service as a possible source for information on unlisted drugs, but I was not able to find this drug through a search of the AHFS website. Any suggestions on how to locate this information would be appreciated. Thank you!
