Ketamine is a controlled medicine in Malaysia (used medically as an anaesthetic and analgesic) but its use as a psychiatric/‘psychedelic’ treatment is generally off‑label and provided on a case‑by‑case basis in clinical or private practice settings. Nationally, ketamine is subject to control under the Dangerous Drugs Act and is recognised in national drug information as a dissociative/ketamine substance; law enforcement seizures demonstrate strict controls on diversion and trafficking. # # Clinical use and reimbursement: medically, ketamine is available in hospital settings (general anaesthesia, emergency medicine) and is sometimes used off‑label by psychiatrists and private clinics for treatment‑resistant depression or acute suicidal ideation; such psychiatric use is not a uniformly funded public‑sector option. Public reimbursement through the Ministry of Health (MOH) hospital formularies for ketamine as an antidepressant is not standardised — access is mostly via private clinics, private hospitals, or specific institutional protocols where costs are borne by the patient or private insurer if covered by policy. Practitioners using ketamine for psychiatric indications should follow institutional governance, informed‑consent processes and any NPRA/DCA guidance related to off‑label prescribing. # #
