Vedolizumab (Entyvio) and Ketamine Therapy | Tovani Health

Entyvio (Vedolizumab)α4β7 integrin monoclonal antibody (gut-selective; UC, Crohn's)

Verdict at Tovani Health

Fully compatible; the gut-selective mechanism makes this one of the cleanest IBD biologics for systemic interaction risk.

Vedolizumab and ketamine have no clinically significant interaction. The gut-selective mechanism is its key feature: by blocking only α4β7 integrin (gut-tropic), it doesn't broadly immunosuppress the way TNF blockers do, which is why it has lower infection risk. Same clean monoclonal antibody profile from a KAP-interaction standpoint.

If you take Entyvio 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 Entyvio interacts with ketamine

Vedolizumab is a humanized mAb that blocks the α4β7 integrin from binding MAdCAM-1, preventing gut lymphocyte trafficking. Cleared by reticuloendothelial system. No CYP interaction with ketamine.
