Desvenlafaxine 50mg/day Desvenlafaxine 100mg/day
Patients will be initiated on 50 mg/day of Desvenlafaxine. No dose changes will be allowed for the first four weeks. If there is partial or no response after four weeks, dosage will then be increased to 100mg/day, based on tolerability and the Investigator's judgment.

Primary objective: To investigate the efficacy, safety, and tolerability of open-label desvenlafaxine monotherapy in dysthymic subjects.
Secondary objectives: To evaluate the efficacy of desvenlafaxine on clinical measures relating to improvement of depressive symptoms, quality of life and occupational functioning.
It is hypothesized that Dysthymic subjects will show significant improvement in depressive symptoms after 8 weeks of treatment with desvenlafaxine. There will be significant improvement in measures of quality of life and stress coping at end of treatment, compared to Baseline. There will also be significant improvement in measures of occupational functioning at end of treatment, compared to Baseline.
