Prophylactic antidepressant treatment in patients with hepatitis C on antiviral therapy: a double-blind,...

Approximately one-third of patients undergoing interferon-α (IFN-α) therapy for treatment of the hepatitis C virus (HCV) develop major depression, which decreases functioning and may lead to the reduction or discontinuation of treatment.

The authors examined the efficacy of citalopram in preventing IFN-α-induced depression in HCV patients.

This was a randomized, controlled trial comparing citalopram with placebo in 39 HCV patients.

The rate of IFN-α-induced depression in the sample was 15.4% (6/39). Randomization to citalopram did not decrease the statistical likelihood of developing IFN-α-induced depression (10.5% for citalopram vs. 20.0% for placebo).

Citalopram does not prevent depression onset; however, an empirically-supported treatment recommendation for IFN-α-induced depression includes monitoring depressive symptoms throughout antiviral therapy and initiating psychiatric treatment at the initial signs of depression.
