For the treatment of Major Depressive Episode Without Melancholia.
PARNATE (tranylcypromine) should be used in adult patients who can be closely supervised. It should rarely be the first antidepressant drug given. Rather, the drug is suited for patients who have failed to respond to the drugs more commonly administered for depression.
The effectiveness of PARNATE (tranylcypromine) has been established in adult outpatients, most of whom had a depressive illness which would correspond to a diagnosis of Major Depressive Episode Without Melancholia. As described in the American Psychiatric Association's Diagnostic and Statistical Manual, third edition (DSM III), Major Depressive Episode implies a prominent and relatively persistent (nearly every day for at least 2 weeks) depressed or dysphoric mood that usually interferes with daily functioning and includes at least 4 of the following 8 symptoms: change in appetite, change in sleep, psychomotor agitation or retardation, loss of interest in usual activities or decrease in sexual drive, increased fatigability, feelings of guilt or worthlessness, slowed thinking or impaired concentration, and suicidal ideation or attempts.
The effectiveness of PARNATE (tranylcypromine) in patients who meet the criteria for Major Depressive Episode with Melancholia (endogenous features) has not been established.
Summary of Contraindications
