Yes: the maximum dosage per day for adults is 225 to 375 mg/day. Starting doses are 37.5to 75 mg/day. Black box warning: monitor for suicidal thoughts. This high dosage could result in serotonin syndrome, which if not treated is as harmful as suicide. "This drug may impair judgment, thinking, and motor skills; therefore, avoid driving or operating machinery if you are affected."
