Brief Summary:
The purpose of this study is to administer a combined oral contraceptive (ethinyl estradiol and norgestimate) with the HIV treatment of atazanavir and ritonavir to healthy females in order to assess if the concentrations of the oral contraceptive change. The safety of this treatment regimen will also be studied.
