  1. To determine whether paroxetine can prevent major depression in patients with hepatitis C (HCV) who are receiving pegylated-interferon (Peg-IFN).
  2. To determine whether paroxetine can prevent subsyndromal increases in depression and anxiety in patients with HCV who are receiving Peg-IFN.
  3. To determine whether paroxetine can prevent a significant change in the health related quality of life in patients with HCV who are receiving Peg-IFN.
  4. To determine whether paroxetine improves compliance with Peg-IFN therapy for HCV.
  5. To determine whether paroxetine enables patients to complete Peg-IFN therapy for HCV who might otherwise require a dose reduction or discontinuation because of neuropsychiatric side effects.
