PARIS or PAtch RIng Study: A Trial to Evaluate NuvaRing Versus OrthoEvra

Summary

This is an open-label prospective, multicenter, randomized trial to compare continuation rates into the fourth cycle of women using either the NuvaRing or OrthoEvra. Five hundred women will be recruited at 9 centers nationwide to be randomly assigned to use either the NuvaRing or OrthoEvra for four months. Women must either be on the pill or have recently stopped the pill and be relatively satisfied with oral contraceptive use to qualify for enrollment. Two visits and two phone calls will be required.
