Ketamine hydrochloride is a registered, prescription-only medicine in Nigeria and is marketed/authorised for clinical use (principally as an anaesthetic); NAFDAC records show approved injectable ketamine products on the national registry. In practice, ketamine is available in public and private hospitals for anaesthesia and emergency medicine under standard medical regulation, but there is no established, publicly reimbursed program for ketamine-based psychiatric treatment (e.g., for treatment‑resistant depression) akin to structured, insured esketamine programs found in some other countries. Off-label psychiatric use would therefore occur on a case-by-case basis in private clinical practice (if practised) and is unlikely to be covered by public insurance; any such use must comply with medicine regulations and professional guidance.
