Hydrocodone (Vicodin, Norco) and Ketamine Therapy | Tovani Health
Vicodin (Hydrocodone) (also: Norco, Lortab) — Opioid analgesic (mu-receptor agonist)
Verdict at Tovani Health
Compatible with the same opioid-sedation precautions as oxycodone.
Hydrocodone and ketamine are compatible with monitoring. Same considerations as oxycodone: additive sedation and respiratory depression, plan timing around the session window.
If you take Vicodin 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 Vicodin interacts with ketamine
Hydrocodone is a mu-opioid agonist with potency roughly equivalent to oral oxycodone. Most formulations contain acetaminophen, which carries its own hepatic dosing limits.
What we do at intake
Disclose dose and any recent changes. Coordinate with your pain prescriber. We may ask you to hold a dose the morning of a session.
Bottom line
Hydrocodone and ketamine are compatible with monitoring. Same considerations as oxycodone: additive sedation and respiratory depression, plan timing around the session window.
