Nefazodone: single versus twice daily dose

Abstract

This pilot study involved six men with major depression treated with nefazodone dosed either twice/day or once/day at bedtime. Depression was rated before nefazodone therapy and at 4 weeks by the self-report version of the Hamilton Depression Rating Scale. A simple 10-cm visual analog side effect scale for daytime drowsiness was completed at the latter time. Dosages of nefazodone were at least 400 mg/day. The results suggest that nefazodone given once/day at bedtime may be as effective as the currently accepted twice/day regimen, with less daytime drowsiness.
