Endogenous cortisol / topical or replacement-dose oralReviewed May 19, 2026

Hydrocortisone (Cortef, OTC) and Ketamine Therapy | Tovani Health

Cortef (Hydrocortisone) (also: Solu-Cortef, OTC creams)Endogenous cortisol / topical or replacement-dose oral

Verdict at Tovani Health

Compatible; the adrenal-insufficiency context is what we plan around for replacement-dose oral.

Hydrocortisone has two distinct uses that need different framing. OTC topical creams (for eczema, insect bites, etc.) have essentially zero systemic effect and are fully compatible with KAP. Oral hydrocortisone at replacement doses (10-30 mg/day) for adrenal insufficiency is medically complex — patients need stress-dose adjustments for any significant stressor (illness, surgery, sometimes psychological stress including intense psychotherapy sessions). We coordinate stress-dose planning with your endocrinologist for KAP days.

If you take Cortef regularly and are considering at-home ketamine therapy, the combination is safe with monitoring or dose adjustment. This page covers the brief pharmacologic context and what we do at intake.

How Cortef interacts with ketamine

Hydrocortisone is bioidentical to endogenous cortisol. Replacement dose mimics normal adrenal output; stress doses (50-100 mg IV) prevent adrenal crisis during major physical stress.

What we do at intake

Disclose use, route, dose, and indication (specifically: adrenal insufficiency, Addison's, congenital adrenal hyperplasia, or just topical use). If you have AI, we coordinate stress-dose planning with your endocrinologist.

Bottom line
