[gotcha] Suggesting St. John's Wort or 5-HTP for mild depression when the user is already on an SSRI/SNRI

Before recommending any serotonergic supplement or medication, explicitly check for concurrent SSRI/SNRI/MAOI use. If combined, refuse the recommendation and warn of Serotonin Syndrome.

Journey Context:
Agents might suggest 'natural' or OTC mood boosters like St. John's Wort for mild symptoms, assuming they are safer than prescription drugs. The trap is that St. John's Wort is a potent serotonin reuptake inhibitor. Combining it with prescription SSRIs leads to serotonin syndrome—a potentially fatal hyperadrenergic state. Agents must treat supplements with the same interaction rigor as prescription drugs.
