Galcanezumab (Emgality) and Ketamine Therapy | Tovani Health
Emgality (Galcanezumab) — CGRP monoclonal antibody (migraine prevention)
Verdict at Tovani Health
Fully compatible; same biologic-class profile as erenumab.
Galcanezumab and ketamine have no clinically significant interaction. Same family as erenumab (Aimovig) and fremanezumab (Ajovy) — monthly subcutaneous CGRP-pathway monoclonal antibodies for migraine prevention. Monoclonal antibodies don't go through CYP and don't have small-molecule interaction surfaces.
If you take Emgality 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.
