Ethoheptazine produces similar effects to other opioids, including analgesia, sedation, dizziness and nausea.[4] It was sold by itself as Zactane, and is still available as a combination product with acetylsalicylic acid and meprobamate as Equagesic, which is used for the treatment of conditions where both pain and anxiety are present.[5] It was also investigated for use as an antitussive.[6]

It is no longer prescribed, as it is no longer FDA approved, and not available for United States' Pharmacy Processing. Revocation of FDA Approved Medications Status stems from a combination of efficacy vs. toxicity, and the more-varied and historically safer Benzodiazepines Class. Only reversal of the FDA's decision, allows removing the drug from the CSD. Ethoheptazine is not listed as a controlled substance under the Controlled Substances Act, 1970 in the United States.[7] The controlled status (Schedule IV) of Equagesic was due to the meprobamate content.[8][9] Regulation elsewhere varies.
