Osimertinib (Tagrisso) and Ketamine Therapy | Tovani Health

Tagrisso (Osimertinib)Third-generation EGFR TKI (EGFR-mutant non-small cell lung cancer)

Verdict at Tovani Health

Fully compatible with KAP; the EGFR-specific side effects are intrinsic.

Osimertinib and ketamine have no clinically significant direct interaction. Standard of care for EGFR-mutant NSCLC. CYP3A4 substrate (a osimertinib concern around strong inhibitors/inducers — affects osimertinib levels, not ketamine). The intrinsic class effects — rash, diarrhea, paronychia, and the more serious pneumonitis and QT prolongation — are EGFR TKI considerations independent of KAP.

If you take Tagrisso 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 Tagrisso interacts with ketamine

Irreversible covalent inhibitor of EGFR with selectivity for activating and resistance T790M mutations. CYP3A4 substrate; weak BCRP inhibitor. No reciprocal effect on ketamine.

What we do at intake

Continue as prescribed. Disclose any concurrent CYP3A4 modulators — that's an osimertinib dose conversation independent of KAP.

Bottom line

Osimertinib and ketamine have no clinically significant direct interaction. Standard of care for EGFR-mutant NSCLC. CYP3A4 substrate (a osimertinib concern around strong inhibitors/inducers — affects osimertinib levels, not ketamine). The intrinsic class effects — rash, diarrhea, paronychia, and the more serious pneumonitis and QT prolongation — are EGFR TKI considerations independent of KAP.
