Modafinil (Provigil) and Ketamine Therapy | Tovani Health
Provigil (Modafinil) (also: Nuvigil) — Wakefulness-promoting agent
Verdict at Tovani Health
Fully compatible with KAP.
Modafinil and ketamine have no clinically significant interaction. Modest CYP3A4 induction is minimal at standard doses; cardiovascular effects are much smaller than amphetamine stimulants. We may ask you to skip the dose on session days for the same general reason we do with any stimulant, not because of a ketamine-specific concern.
If you take Provigil 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 Provigil interacts with ketamine
Modafinil's exact mechanism is incompletely understood but involves dopamine transporter inhibition and orexin signaling. Mild CYP3A4 induction is documented. Cardiovascular effects are typically smaller than amphetamines.
What we do at intake
Disclose dose and indication (narcolepsy, shift work, off-label cognitive). Take in the morning as usual.
Bottom line
Modafinil and ketamine have no clinically significant interaction. Modest CYP3A4 induction is minimal at standard doses; cardiovascular effects are much smaller than amphetamine stimulants. We may ask you to skip the dose on session days for the same general reason we do with any stimulant, not because of a ketamine-specific concern.
