Prilosec (Omeprazole)Proton pump inhibitor (PPI)

Verdict at Tovani Health

Compatible; no meaningful interaction with KAP.

Omeprazole and ketamine have no clinically significant interaction. PPIs are commonly on board for KAP patients with GERD and do not change session planning.

If you take Prilosec 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 Prilosec interacts with ketamine

Omeprazole inhibits gastric H+/K+ ATPase. Metabolized by CYP2C19. Minor CYP impact on ketamine but not clinically meaningful.

What we do at intake

Continue as normal.

Bottom line

Omeprazole and ketamine have no clinically significant interaction. PPIs are commonly on board for KAP patients with GERD and do not change session planning.

Frequently Asked Questions
