Rizatriptan (Maxalt) and Ketamine Therapy | Tovani Health
Maxalt (Rizatriptan) — 5-HT1B/1D receptor agonist (triptan)
Verdict at Tovani Health
Fully compatible; same updated guidance as sumatriptan.
Rizatriptan and ketamine have no clinically significant interaction. The triptan-plus-serotonergic-drug serotonin syndrome concern was walked back by the American Headache Society 2018 position statement. With ketamine, which is not meaningfully serotonergic, the concern is essentially nil.
If you take Maxalt 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.

Bottom line
Rizatriptan and ketamine have no clinically significant interaction. The triptan-plus-serotonergic-drug serotonin syndrome concern was walked back by the American Headache Society 2018 position statement. With ketamine, which is not meaningfully serotonergic, the concern is essentially nil.
