Premenstrual syndrome is primarily diagnosed clinically, with consistent characteristic symptoms occurring in the luteal phase of the menstrual cycle and resolving during menstruation or within the week following it. For a premenstrual dysphoric disorder diagnosis, a patient’s symptoms must substantially interfere with work, school, social activities, or relationships or cause significant distress. Patients should record symptoms for at least two cycles because symptoms can vary from cycle to cycle. A symptom-tracking diary or diagnostic instrument, such as the Daily Record of Severity of Problems (a validated prospective survey tool), can be used to identify the cyclic pattern of symptoms. Selective serotonin reuptake inhibitors are first-line treatment for premenstrual syndrome and premenstrual dysphoric disorder, with rapid onset of improvement; however, adverse effects can limit their use. Cognitive behavior therapy, exercise, acupuncture or acupressure, and the herb Vitex agnus castus may be used to ameliorate premenstrual syndrome and premenstrual dysphoric disorder symptoms. Reassessment for another underlying cause of premenstrual dysphoric disorder symptoms should occur if symptoms are not controlled with medications or other interventions or persist throughout the month.
Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) manifest in a spectrum of physical and psychological symptoms that occur cyclically in the luteal phase of the menstrual cycle and resolve during menstruation or within the week following it.1 Symptoms of the two disorders include marked affective lability (mood swings), bloating, lethargy, irritability, anxiety and feelings of being out of control, appetite changes, sleep disturbances, and decreased interest in usual activities.2 Up to 90% of women of reproductive age have at least one physical or affective symptom.1,2 PMS affects approximately 20% to 30% of women, with about 2% to 5% reporting symptoms severe enough to meet the diagnostic criteria of PMDD.3–5 Although treatment has historically included multiple modalities, evidence-based treatment for PMS and PMDD is limited by the lack of recent, high-quality research. An approach for treatment is provided in Figure 1.
WHAT’S NEW ON THIS TOPIC

| A 2024 systematic review showed that continuous dosing of selective serotonin reuptake inhibitors is more effective than intermittent dosing for relief of premenstrual syndrome and premenstrual dysphoric disorder symptoms. |
| A 2021 meta-analysis of combined oral contraceptives showed moderate effectiveness in relieving overall premenstrual syndrome symptoms but no difference in affective symptoms than placebo. |
| A healthy diet and calcium supplementation may be recommended for general health; however, no good evidence shows that either one improves premenstrual syndrome symptoms. |
SORT: KEY RECOMMENDATIONS FOR PRACTICE

| Clinical recommendation | Evidence rating | Comments |
|---|---|---|
| Selective serotonin reuptake inhibitors are recommended as first-line therapy for PMS and PMDD, according to studies showing reduced overall self-rated symptoms.10,11,13,14 | A | Multiple RCTs, systematic reviews, and meta-analyses |
| Cognitive behavior therapy may improve some of the physical and psychological symptoms of PMS and PMDD.21,22 | B | Low-quality studies |
| Exercise reduces physical and psychological symptoms of PMS compared with no exercise.24 | B | Meta-analysis of seven RCTs with high heterogeneity of studies |
PMDD = premenstrual dysphoric disorder; PMS = premenstrual syndrome; RCT = randomized controlled trial.
A = consistent, good-quality patient-oriented evidence; B = inconsistent or limited-quality patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, expert opinion, or case series. For information about the SORT evidence rating system, go to https://www.aafp.org/afpsort.
