Furosemide (Lasix) and Ketamine Therapy | Tovani Health
Lasix (Furosemide) — Loop diuretic
Verdict at Tovani Health
Compatible; hydration and BP matter more here than with thiazides.
Furosemide and ketamine are compatible. Furosemide is a more potent diuretic than HCTZ; volume depletion plus ketamine's transient sympathomimetic effect can cause more pronounced BP fluctuations. We make sure patients are well-hydrated and monitor BP.
If you take Lasix 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 Lasix interacts with ketamine
Furosemide inhibits the Na-K-2Cl cotransporter in the loop of Henle, producing strong diuresis. Used for heart failure, edema, and refractory hypertension. No overlap with ketamine pharmacology.
What we do at intake
Disclose dose and indication. Be well-hydrated on session day unless your fluid restriction is medically necessary (heart failure patients should check with their cardiologist before adjusting hydration).
Bottom line
Furosemide and ketamine are compatible. Furosemide is a more potent diuretic than HCTZ; volume depletion plus ketamine's transient sympathomimetic effect can cause more pronounced BP fluctuations. We make sure patients are well-hydrated and monitor BP.
