Diagnosis and Treatment of
Premenstrual Dysphoric Disorder
Creighton University School of Medicine, Omaha, Nebraska
From 2 to 10 percent of women of reproductive age have severe distress and dysfunction
caused by premenstrual dysphoric disorder, a severe form of premenstrual syndrome.

Current research implicates mechanisms of serotonin as relevant to etiology and treat-
tion handout on pre-menstrual dysphoric ment. Patients with mild to moderate symptoms of premenstrual syndrome may benefit
from nonpharmacologic interventions such as education about the disorder, lifestyle
changes, and nutritional adjustments. However, patients with premenstrual dysphoric
disorder and those who fail to respond to more conservative measures may also require
pharmacologic management, typically beginning with a selective serotonin reuptake
inhibitor. This drug class seems to reduce emotional, cognitive-behavioral, and physical
symptoms, and improve psychosocial functioning. Serotoninergic antidepressants such
as fluoxetine, citalopram, sertraline, and clomipramine are effective when used intermit-
tently during the luteal phase of the menstrual cycle. Treatment strategies specific to the
luteal phase may reduce cost, long-term side effects, and risk of discontinuation syn-
drome. Patients who do not respond to a serotoninergic antidepressant may be treated
with another selective serotonin reuptake inhibitor. Low-dose alprazolam, administered
intermittently during the luteal phase, may be considered as a second-line treatment. A
therapeutic trial with a gonadotropin-releasing hormone agonist or danazol may be con-
sidered when other treatments are ineffective. However, the risk of serious side effects
and the cost of these medications limit their use to short periods. (Am Fam Physician
