Initial selection of oral contraceptives.
A prospective, randomized trial compared client experiences with three popular oral contraceptives--Triphasil, Ortho-Novum 7/7/7 and Ortho-Novum 1/35. After one year, no significant relationship was found between the contraceptive prescribed and either breakthrough bleeding or satisfaction with the medication. The monophasic formulation, Ortho-Novum 1/35, was associated with amenorrhea more often.
