  • Agree to use an adequate method of birth control for the duration of the study to avoid pregnancy. Acceptable methods include a history of tubal ligation, male partner with a vasectomy, a steroidal contraceptive (oral, patch, injectable or implantable), IUD (Paragard or Mirena), condoms or abstinence.
