Are patients who are intolerant to one serotonin selective reuptake inhibitor intolerant to another?

BACKGROUND

The question was asked whether patients who discontinue one serotonin selective reuptake inhibitor (SSRI) because of side effects can be treated successfully with another SSRI.

METHOD

113 patients with major depression who had discontinued fluoxetine because of side effects were enrolled in an open, multicenter, 8-week study designed to evaluate the tolerability and efficacy of sertraline. After a washout period of at least 3 weeks following fluoxetine discontinuation and an additional 1-week, single-blind, placebo washout period, patients began treatment with 50 mg of sertraline once daily. Doses were titrated upward as necessary to a maximum daily dose of 200 mg. Depressive symptoms and adverse events were evaluated weekly.

RESULTS

Based on the Clinical Global Impressions Scale, 79 (71.8%) of 110 patients evaluated for efficacy were "much" or "very much" improved relative to baseline. Only 11 (9.8%) of 112 patients discontinued sertraline because of adverse reactions.

CONCLUSION

These results suggest that patients who discontinue one SSRI because of side effects can be treated successfully with another.
