Harm Potential

Addiction & Dependence

Psychological

High

Experiments on former addicts indicated ketobemidone was quite addictive with potentially increased abuse potential in high doses compared to other opioids. However, conflicting evidence suggests that at analgesic doses it may produce less euphoria than morphine, potentially reducing addiction risk under clinical supervision.

Physical

High

As an opioid, ketobemidone carries a high risk of physical dependence with chronic use, consistent with its classification as habit-forming.

Toxicity

Lethal Dosage

Overdose may lead to respiratory depression and death. No specific lethal dose values are documented in available sources.

Respiratory

Overdose can produce fatal respiratory depression; people with asthma warrant extra caution because CNS depression can worsen respiratory risk.
