Abstract BACKGROUND: Depression commonly complicates treatment with the cytokine interferon alfa-2b. Laboratory animals pretreated with antidepressants have less severe depression-like symptoms after the administration of a cytokine. We sought to determine whether a similar strategy would be effective in humans. METHODS: In a double-blind study of 40 patients with malignant melanoma who were eligible for high-dose interferon alfa therapy, we randomly assigned 20 patients to receive the antidepressant paroxetine and 20 to receive placebo. The treatment was begun 2 weeks before the initiation of interferon alfa and continued for the first 12 weeks of interferon alfa therapy. RESULTS: During the first 12 weeks of interferon alfa therapy, symptoms consistent with a diagnosis of major depression developed in 2 of 18 patients in the paroxetine group (11 percent) and 9 of 20 patients in the placebo group (45 percent) (relative risk, 0.24; 95 percent confidence interval, 0.08 to 0.93). Severe depression necessitated the discontinuation of interferon alfa before 12 weeks in 1 of the 20 patients in the paroxetine group (5 percent), as compared with 7 patients in the placebo group (35 percent) (relative risk, 0.14; 95 percent confidence interval, 0.05 to 0.85). The incidence of adverse events was similar in the two groups. CONCLUSIONS: In patients with malignant melanoma, pretreatment with paroxetine appears to be an effective strategy for minimizing depression induced by interferon alfa.
