Medical management of premenstrual syndrome.

Premenstrual syndrome (PMS) is characterized by a wide variety of symptoms occurring over several days before menstruation. In the differential diagnosis, family physicians should consider other conditions such as chronic yeast infection, allergy, stress, hypoglycemia and primary dysmenorrhea. Each patient should complete a daily menstrual diary for two to three monthly cycles. This diary may help the physician to determine the cyclical nature of PMS and specific symptoms. For most PMS sufferers, initial treatment involves the physician's acknowledgement of the problem and advice about lifestyle, dietary modification and vitamin supplements (e.g., pyridoxine). Seven steps are recommended to assist the family physician in the practical office management of most women with PMS. The potential role of progesterone and other agents in the treatment of PMS is described. Referral to a psychiatrist or psychologist, or the use of drugs such as lithium, danazol or bromocriptine may be required for women suffering from severe PMS.
