By contrast, recent retrospective studies suggest that the rate of flare is not significantly increased in patients taking OCs. The preexisting data is insufficient to warrant the dismissal of a potentially important birth control option in a disease that predominantly affects women in their reproductive years and whose fertility is not altered by the disease. Moreover, the use of OCs to preserve fertility in patients taking cyclophosphamide and the use of estrogens to prevent coronary artery disease and postmenopausal and steroid-induced osteoporosis are timely considerations.
