Isocarboxazid. Efficacy and tolerance

In a double-blind study, isocarboxazid was found to have greater efficacy than placebo. Patients with weight gain, increased appetite, and increased sleep responded particularly well, with a rapid onset of improvement that was apparent by one week. Their response to placebo was poor. Using a flexible dose, the modal range was 30-60 mg per day. Higher doses were poorly tolerated. At the doses used, side effects were generally mild, the most common being dizziness and myoclonus.
