Oxymorphone (Opana) and Ketamine Therapy | Tovani Health

Opana (Oxymorphone)Potent opioid analgesic

Verdict at Tovani Health

Compatible with the same close-monitoring approach used for other potent opioids.

Oxymorphone and ketamine are compatible with appropriate monitoring. Oxymorphone is more potent than oxycodone (it's the active metabolite of oxycodone) and sits between morphine and hydromorphone in the potency hierarchy. Same considerations as those: additive respiratory depression and sedation, careful dose coordination.

If you take Opana regularly and are considering at-home ketamine therapy, the combination is safe with monitoring or dose adjustment. This page covers the brief pharmacologic context and what we do at intake.

How Opana interacts with ketamine

Oxymorphone is a semi-synthetic mu-opioid agonist. Higher potency than morphine. Reformulated extended-release product was discontinued in the US due to abuse concerns, but immediate-release and generic ER remain available.

What we do at intake

Disclose dose, formulation, and indication. Coordinate with your pain prescriber.

Bottom line

Oxymorphone and ketamine are compatible with appropriate monitoring. Oxymorphone is more potent than oxycodone (it's the active metabolite of oxycodone) and sits between morphine and hydromorphone in the potency hierarchy. Same considerations as those: additive respiratory depression and sedation, careful dose coordination.
