Naratriptan (Amerge) and Ketamine Therapy | Tovani Health
Amerge (Naratriptan) — Triptan (5-HT1B/1D agonist; acute migraine, menstrual migraine prevention)
Verdict at Tovani Health
Fully compatible; longer-half-life triptan used for menstrual migraine prophylaxis.
Naratriptan and ketamine have no clinically significant interaction. Distinctive among triptans for its longer half-life (~6 hours) and slower onset, which makes it well-suited for menstrual migraine prophylaxis (scheduled dosing around the period rather than acute rescue). Same updated guidance on SS framing as the other triptans.
If you take Amerge 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.
