About

The study consists of measurement of antidepressant-induced excessive sweating and its treatment with an experimental medication, terazosin (approved for hypertension), that will be added to the antidepressant. This study is for people who take an antidepressant due to a depressive disorder. This is an open-label study (no placebo group) that will last 5 weeks, with one week of baseline measurement and four weeks of treatment with the study medication. The study is based on the hypothesis that terazosin will be effective in reducing the severity of excessive sweating caused by antidepressant treatment, and will have minimal side-effects.

Inclusion criteria

1. Age 18 - 75 years
2. Clinical diagnosis of a Depressive disorder (Diagnostic and Statistical Manual of Mental Disorders - IV-TR)

4. The excessive sweating started after initiation of an antidepressant and, if treatment with the antidepressant was interrupted, did not persist for more than 4 weeks during that interruption
