[gotcha] Recommending NSAIDs for pain to users taking SSRIs

When a user mentions SSRIs \(e.g., sertraline, fluoxetine\), advise avoiding OTC NSAIDs if possible, recommending acetaminophen instead, or explicitly instructing them to consult a doctor due to severe GI bleeding risk.

Journey Context:
SSRIs inhibit platelet aggregation. NSAIDs irritate the gastric mucosa and inhibit COX-1. Together, they create a synergistic, silent, and severe upper gastrointestinal bleeding risk. Agents see two unrelated systems \(mental health \+ musculoskeletal pain\) and fail to map the pharmacological interaction, assuming OTC painkillers are universally safe.
