Chronic pelvic pain: oral contraceptives and non-steroidal anti-inflammatory compounds.

A correct classification of female pelvic pain originating from gynaecological disorders is essential if the most appropriate therapy is to be chosen. Certain types of non-steroidal anti-inflammatory drugs and oral contraceptives reduce the production of prostaglandins, which are responsible in large part for primary dysmenorrhoea. Oestroprogestin formulations become the drugs of choice if the patient also requests contraception. Secondary dysmenorrhoea and chronic pelvic pain may require combined medical and surgical treatment. Oral contraceptives can also be used as post-treatment agents in endometriosis, one of the most common causes of pelvic pain, whereas more specific compounds (GnRH-analogues and Danazol) are used to produce anatomical regression of endometriosis.
