Charcoal absorbs Prozac, reducing its effectiveness.
Activated charcoal adsorbs fluoxetine in GI tract, reducing absorption.
Take Prozac at least 2 hours before or 4 hours after charcoal.
Take Fluoxetine at the same time each day as prescribed. Activated Charcoal can be taken at any convenient time — morning with breakfast is typical. If the supplement has serotonergic properties (5-HTP, SAMe, tryptophan), use extreme caution or avoid entirely, as combining with an SSRI risks serotonin syndrome. Fish oil, CoQ10, and probiotics are generally safe alongside SSRIs.
