KEY POINTS
1. Trials have found that SSRIs and prostagalndin inhibitors relieve premenstrual symptoms. Antidepressants and ovulation suppression with danazol and GnRH analoges are also effective but have significant adverse effects, including the masculanising effects of danazol and the menopausal effects of GnHR analogues.
2. There is a limited evidence suggesting that oestrogen, viatmin-B6 , evening Primrose Oil and excercise may also be beneficoial
3. Trials have found that bromocriptine is effective for breast symptoms and diuretics are effective for bloatedness and swelling. Both can have adverse efects.
4. There is no good evidence to support the use of progesterone or oral contraceptives
5. Few treatments have been adequately validated in trials.
