This pilot study involved six men with major depression treated with n
efazodone dosed either twice/day or once/day at bedtime. Depression wa
s rated before nefazodone therapy and at 4 weeks by the self-report ve
rsion of the Hamilton Depression Rating Scale. A simple 10-cm visual a
nalog side effect scale for daytime drowsiness was completed at the la
tter 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 drowsin
ess.
