Abstract
Objective:
There is no commonly accepted standard for comparing antidepressant- induced side effects. This study evaluates a clinician- administered scale, the Toronto Side Effect Scale (TSES), in a natural practice clinic.
Method:
We used the TSES to assess side effects in 193 depression patients who completed 8 weeks of treatment with either bupropion, mo clobe mide, paroxetine, ser tra line, or venlafaxine.
Results:
Rates of remission (Hamilton Rating Scale for Depression [HRSD] < 7) did not differ across drugs after 8 weeks of treatment. Paired drug comparisons yielded significant differences in 16 of the 32 side effects. We present differences between pairs of the 5 antidepressants in Central Nervous System (CNS), gastrointestinal (GI), and sexual side effects. A measure of side-effect intensity distinguished paroxetine from the other antidepressants on a measure of sexual dysfunction.
Conclusions:
These results con firm the clinical utility of the TSES as a simple, clinician-administered antidepressant side-effect scale.
