Premenstrual dysphoric disorder in adolescents: case reports of treatment with fluoxetine and review of the literature.

Premenstrual dysphoric disorder (PMDD) is a periodic, recurrent, debilitating condition with severe psychological or affective symptoms during the late luteal phase. PMDD often begins during adolescence. Dysregulation of the serotonergic system has been proposed recently as its cause and fluoxetine has been recommended as an appropriate treatment. We report 3 adolescents with PMDD who were treated for 2 years with fluoxetine, resulting in complete symptom resolution, and review the clinical trials supporting its use. Case reports of successfully treated teenagers are an addition to the accumulated evidence of the efficacy of fluoxetine for treatment of PMDD in adult women. Together they may provide some justification for the compassionate use of fluoxetine for adolescent girls who are being disabled by PMDD. However, more research is called for: a randomized placebo-controlled trial in adolescents is warranted.
