Oseltamivir (Tamiflu) and Ketamine Therapy | Tovani Health
Tamiflu (Oseltamivir) — Antiviral (influenza A and B)
Verdict at Tovani Health
Fully compatible with KAP.
Oseltamivir and ketamine have no clinically significant interaction. The standard 5-day Tamiflu course for influenza or longer prophylactic use can continue alongside KAP. The practical question is usually whether you should run a session while you're sick with flu — that answer is separate from the Tamiflu interaction question (we usually defer the session until you feel well).
If you take Tamiflu 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 Tamiflu interacts with ketamine

What we do at intake
Continue the course as prescribed. Tell us if you're symptomatic with flu when scheduling — we usually defer sessions until you're well.
