The prophylaxis of unipolar depression is still a controversial subjec
t. Some authors prefer lithium, others maintenance treatment with anti
depressants. The role of carbamazepine remains unclear. Few patients h
ave been described in the literature, and most are lithium nonresponde
rs or rapid cyclers. In an open-label naturalistic study, 15 patients
suffering from unipolar depression (DSM-III, 296.2, 296.3) and receivi
ng long-term prophylaxis with carbamazepine were followed for 5 years.
Four had been pretreated with lithium without satisfactory effects, 1
1 were prophylaxis naive. The mean time span patients received carbama
zepine was 49.5 months. 73% of the patients gained substantial profit
from carbamazepine. Side effects were infrequent.
