Objectives

To evaluate the safety and efficacy of 5 mg and 25 mg doses of mifepristone for the treatment of endometriosis.

Design

Randomized double-blind study.

Setting

Eusebio Hernández Hospital, Havana, Cuba.

Subjects

Twenty-six women laparoscopically diagnosed with endometriosis were included.

Treatment

Group I received one tablet of 25 mg mifepristone daily and group II received one tablet of 5 mg mifepristone daily for 6 months. Laparoscopy and endometrial biopsy were performed before and after treatment.

Variable to evaluate efficacy

Reduction in the intensity of dysmenorrhea measured by a visual analogue scale.

Results

In both groups reductions in the intensity of dysmenorrhea and dyspareunia were highly significant compared with initial values (P <.001). All the women were amenorrheic after 45 days of treatment.

Conclusions

At doses of 5 mg or 25 mg, mifepristone could be an alternative for the treatment of endometriosis.
