Depot medroxyprogesterone acetate versus an oral contraceptive combined with very-low-dose danazol for long-term treatment of pelvic pain associated with endometriosis.
OBJECTIVE Our purpose was to evaluate the efficacy and safety of depot medroxyprogesterone acetate versus an oral contraceptive combined with very-low-dose danazol in the long-term treatment of pelvic pain in women with endometriosis . STUDY DESIGN Eighty patients with endometriosis and moderate or severe pelvic pain were r and omized to treatment for 1 year with intramuscular depot medroxyprogesterone acetate 150 mg every 3 months or a cyclic monophasic oral contraceptive ( ethinyl estradiol 0.02 mg , desogestrel 0.15 mg ) combined with oral danazol 50 mg a day for 21 days of each 28-day cycle . The women were asked to grade the degree of their satisfaction at the end of therapy . Variations in severity of symptoms during treatment were determined by a 10 cm visual analog and a 0- to 3-point verbal rating scale . RESULTS Twenty nine of 40 subjects ( 72.5 % ) in the depot medroxyprogesterone acetate group were satisfied after 1 year of therapy compared with 23 of 40 ( 57.5 % ) in the oral contraceptive plus danazol group ( chi 2(1 ) = 1.37 , p = 0.24 , odds ratio 1.95 , 95 % confidence interval 0.76 to 4.97 ) . A significant decrease was observed in all symptom scores in both study groups . At 1-year assessment dysmenorrhea was significantly greater in women allocated to oral contraceptive plus danazol . CONCLUSION Depot medroxyprogesterone acetate seems to be an effective , safe , and convenient low-cost treatment for pelvic pain associated with endometriosis . However , women should be carefully counseled regarding menstrual changes and the potential prolonged delay in the return of ovulation
