Premenstrual syndrome encompasses physical and psychological symptoms arising in the luteal phase of the menstrual cycle. When symptoms reach moderate to severe intensity, a structured pharmacological or psychological management strategy is indicated.
Management of moderate to severe PMS may involve a psychological approach — including SSRI antidepressants and/or cognitive behavioural therapy — alongside or as an alternative to hormonal cycle suppression strategies; the full protocol specifies which interventions apply, in what combination, and under what conditions.
