This expensive drug basically offers the same anti-depressant activity as the generic forms of Prozac, Zoloft, Paxil or Celexa but at a much greater price. For some unknown reason nausea remains a common, long lasting side effect. Nowhere in the barrage of televised advertising is there mention that the daily cost of the drug exceeds $10 versus $3-10 for one month of the generic versions of selective serotonin reuptake inhibitors.
