Purpose
The purpose of this study is to determine if blood levels of the hormonal emergency contraceptive agent, Plan B, are altered by concomitant use with the HIV medication, efavirenz.

Further study details as provided by University of Colorado, Denver:
Primary Outcome Measures:
- The change in Plan B (levonorgestrel) Area under the Concentration Time Curve (AUC12) prior to and during steady state efavirenz [ Time Frame: 12 hour pharmacokinetic study ]
Secondary Outcome Measures:
- Pharmacokinetic parameters of levonorgestrel prior to and during steady state efavirenz [ Time Frame: 12 hour pharmacokinetic study ]
- Frequency of common levonorgestrel-associated adverse events prior to and during steady-state efavirenz [ Time Frame: 3 weeks ]
- Changes in liver function tests before and during efavirenz [ Time Frame: 3 weeks ]
- The efavirenz Area Under the Concentration Time Curve (AUC 24) in setting of levonorgestrel compared to historical controls [ Time Frame: 12 hour pharmacokinetic study ]

The use of hormonal contraceptive pills in women with HIV is complex due to potential interactions between these agents and HIV medications. HIV-infected women taking efavirenz have an even greater need for effective birth control as this medication may cause severe brain damage to a developing fetus. The use of an emergency contraceptive agent in cases of unprotected sex or condom failure can prevent pregnancy. This study seeks to establish that Plan B can be used effectively and safely in women taking efavirenz.
