Understanding Depression Slideshow

PREGNANCY: There are no adequate studies of nefazodone in pregnant women.

NURSING MOTHERS: Nefazodone may be secreted in breast milk and may cause adverse effects in the nursing infant.

SIDE EFFECTS: The most commonly noted side effects associated with nefazodone are nausea, dizziness, insomnia, agitation, tiredness, dry mouth, constipation, lightheadedness, blurred vision, and confusion. Rarely, nefazodone is associated with priapism or prolonged penile erection. Compared with trazodone, nefazodone has a lesser risk of priapism (prolonged penile erection). Although the erection usually subsides eventually, occasionally blood clots form within the penis and cause serious damage to the penis. Nefazodone rarely may cause liver failure that may result in liver transplantation.

If antidepressants are discontinued abruptly, symptoms may occur such as dizziness, headache, nausea, changes in mood, or changes in the sense of smell, taste, etc. (Such symptoms even may occur when even a few doses of antidepressant are missed.) Therefore, it is recommended that the dose of antidepressant be reduced gradually when therapy is discontinued.

Antidepressants increased the risk of suicidal thinking and behavior in short-term studies in children and adolescents with depression and other psychiatric disorders. Anyone considering the use of nefazodone or any other antidepressant in a child or adolescent must balance this risk of suicide with the clinical need. Patients who are started on therapy should be closely observed for clinical worsening, suicidal thoughts, or unusual changes in behavior.
