Report #8711

[gotcha] Can a patient take St. John's Wort alongside their SSRI antidepressant for a boost in mood?

Explicitly warn against combining St. John's Wort with SSRIs/SNRIs due to the risk of Serotonin Syndrome, a potentially fatal condition. Also warn it reduces efficacy of oral contraceptives and other drugs.

Journey Context:
'Natural' supplements are often treated as harmless add-ons. St. John's Wort is a potent serotonin reuptake inhibitor and CYP450 inducer. Combining it with prescription SSRIs pushes serotonin to toxic levels \(hyperreflexia, fever, seizures\), while simultaneously rendering other drugs like birth control ineffective.
