Pitolisant and Ketamine: What to Monitor
Wakix (Pitolisant) — Histamine H3 receptor inverse agonist (narcolepsy)
Verdict at Tovani Health
Compatible; novel mechanism with QT and CYP considerations worth flagging.
Pitolisant and ketamine are compatible. Pitolisant is unique among wakefulness-promoting agents — it's an inverse agonist at H3 histamine receptors that increases histamine release in wakefulness-promoting brain regions. Three practical considerations: it's a major CYP2D6 substrate (so poor metabolizers reach much higher exposures); it has modest intrinsic QT prolongation (independent of KAP); and as a non-stimulant it lacks the cardiovascular stack other narcolepsy meds have.
If you take Wakix regularly and are considering at-home ketamine therapy, the combination is safe with monitoring or modest dose adjustment. This page covers the brief pharmacologic context and what we do at intake.
How Wakix interacts with ketamine
Pitolisant is an inverse agonist / antagonist at H3 receptors, raising central histamine and other wakefulness-promoting neurotransmitters. CYP2D6 substrate. Modest QT prolongation. No direct ketamine PK interaction.
What we do at intake
Disclose dose. Bring a recent EKG if you have one. Tell us about CYP2D6-modulating medications.
