[Choice of antidepressant treatment after a major depressive episode].

The choice of an antidepressant is not necessary during the initial phase of only treatment (acute treatment), it can be reviewed after one or two months (continuation treatment) and a prophylactic treatment may be discussed after a 6 months period (long-term maintenance treatment). Many reasons explain the need to readjust the dosage of antidepressant treatment or to change it: the nature and the gravity of the depression, the family and personal history of affective disorders, the level of side effects and above all the quality of the recovery. Thus the modification of a treatment can be considered according to 4 methods: modification of the psychotropes associated to antidepressant treatment, association of a second antidepressant medication, change of antidepressant medication, institution of a prophylactic treatment. A special aspect concerns the decision and the choice of the antidepressant treatment after recovery by E.C.T. Two types of treatment can be considered: most often a maintenance treatment of antidepressant medication is suggested. Prolongation of ECT may be justified for consolidation: 6 or 8 sessions after recovery, or for prevention of relapse: session every 3-4 weeks after recovery, and for a period of 2-3 years.
