Practical advice

Timing

Take Paroxetine at the same time each day as prescribed. L-Dopa 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.

Higher risk for: elderly, those on multiple serotonergic drugs, people with liver impairment, CYP2D6 poor metabolizers, recent dose changes, or concurrent use of MAOIs or triptans.
