Semaglutide (Wegovy, Rybelsus) and Ketamine Therapy | Tovani Health
Wegovy (Semaglutide) (also: Rybelsus) — GLP-1 receptor agonist (weight loss / type 2 diabetes)
Verdict at Tovani Health
Fully compatible; no meaningful interaction with KAP.
Semaglutide and ketamine have no clinically significant interaction. Whether you take it as Wegovy for weight loss, Rybelsus orally for diabetes, or Ozempic by injection (covered separately), KAP proceeds without medication changes. The only practical note: GLP-1 agonists slow gastric emptying, which can theoretically affect oral medication absorption, but ketamine is typically given sublingually or via injection rather than swallowed.
If you take Wegovy regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.
How Wegovy interacts with ketamine
Semaglutide agonizes GLP-1 receptors, slowing gastric emptying and increasing insulin response. No overlap with ketamine pharmacology.
What we do at intake
Continue as normal. Disclose if you have significant GI side effects from the GLP-1 (some patients experience nausea that can compound with session-day jitters).
Bottom line
Semaglutide and ketamine have no clinically significant interaction. Whether you take it as Wegovy for weight loss, Rybelsus orally for diabetes, or Ozempic by injection (covered separately), KAP proceeds without medication changes. The only practical note: GLP-1 agonists slow gastric emptying, which can theoretically affect oral medication absorption, but ketamine is typically given sublingually or via injection rather than swallowed.
Frequently Asked Questions
I take Wegovy and feel nauseous a lot. Will ketamine make it worse?
Possibly mildly. We can use ondansetron prophylactically and time sessions for windows when GLP-1 nausea is lowest for you.
Ready to find out if at-home ketamine fits your situation?
We’ll note that you’re on Wegovy (Semaglutide) at intake. The eligibility check takes 5 minutes and gives you an honest answer about whether at-home ketamine fits your specific situation.
