Diagnosis

Diagnosis

The major differentials are psychiatric syndromes, particularly depressive disorders and/or dysthymia. Other entities may be suggested by history or physical.

Laboratory
There are no laboratory tests which confirm or refute PMS. History and physical may disclose a need for specific laboratory tests.

Drugs that may alter lab results: N/A

Disorders that may alter lab results: N/A

Diagnostic Procedures
Patients complete questionnaires over a minimum of two months to confirm premenstrual exacerbation of symptoms and lack of substantial symptoms in the follicular phase

Treatment

Medications

Drugs of choice
No single drug works for all women. Drugs that are used with varying degrees of success are listed.

• Antidepressants [fluoxetine (Prozac, Sarafem), sertraline, clomipramine, citalopram or nortriptyline], particularly for patients with depressive symptoms. Antidepressants can work when used only during the luteal phase of the menstrual cycle.
• Elemental calcium 1000 mg/day
• Diuretics (usually spironolactone) during luteal phase
• Symptomatic treatment of pain (ibuprofen or acetaminophen)
• Vitamin B6 in modest doses (50 mg bid, may be toxic in higher doses)
• Vitamin E: up to 600 IU/day
• Evening primrose oil, high content of fatty acids, 500 mg qd to 1000 mg tid for breast tenderness, believed to decrease prostaglandin synthesis
• Oral contraceptives may help
• Bromocriptine 2.5 mg tid at time of symptoms and danazol 100 mg bid may also work for breast tenderness, but have more side effects
• Danazol for the total PMS symptom complex
• Gonadotropin-releasing hormone agonists with or without concurrent estrogens/progestins
• L-tryptophan 2 g three times a day
