Treatment of premenstrual syndrome: a decision-making algorithm.

The aim of this short paper will be to guide the clinician through the plethora of possible interventions to help them to individualize treatment for their patients with PMS. The discussion will highlight management principles rather than evidence per se. It uses as its basis an updated version of the treatment algorithm published by the RCOG in its Green Top Guideline no. 48 on the management of PMS.
