Safety & trade-offs3▾
CONTRAINDICATED with SSRIs, SNRIs, MAOIs, tramadol, and triptans — serotonin syndrome risk (potentially fatal)
GI side effects (nausea, diarrhea) are common — start at 50mg and always take with food
Long-term use may theoretically deplete dopamine via serotonin pathway dominance — consider cycling
