8. Females of reproductive potential who are participating in sexual activity that could lead to pregnancy must agree to use two of the following forms of birth control while receiving TB study medications and for 30 days after stopping study medications : male or female condoms, diaphragm or cervical cap (with spermicide, if available), intrauterine device (IUD) or intrauterine system (IUS), and hormone-based birth control (e.g., oral contraceptives, Depo-Provera, NuvaRing, implants).
