Relapse prevention in recurrent major depressive disorder. A comparison of different treatment options based on clinical experience and a critical review of the literature.

Background: Reducing the risk of relapses is a critical component of major depressive disorders treatment. Guidelines suggest maintenance with antidepressant drugs in recurrent depression, but this solution has recently been questioned.

Objective: The aim of this article is to provide a critical review of the literature of the main treatment options currently available to prevent relapse and recurrence in depression.

Methods: We compared long-term antidepressant therapy (i.e., indefinite maintenance of antidepressant), intermittent antidepressant therapy (i.e., use of antidepressants mainly limited to the acute phases), use of psychotherapy in the sequential model (i.e., pharmacotherapy in the acute phase and psychotherapy in the residual phase).

Results: We argue that the same solution may not apply to all patients and question the feasibility of a single course of treatment in the setting of complex disorders that are encountered in practice. The clinician should weigh advantages and disadvantages in the individual case.

Conclusions: The sequential model appears to be particularly indicated in recurrent depression. KEY POINTS Relapse is a major challenge of depressive disorders treatment Treatment options currently available include long-term antidepressants, intermittent antidepressants, addition of psychotherapy to pharmacotherapy in the sequential model Maintenance with antidepressants in recurrent depression has recently been questioned The sequential model appears to be particularly indicated in recurrent depression.
