  • Women either must be 1 year post-menopausal, surgically sterile, or if they are of child-bearing potential, they must: a) have been using systemic birth control, intrauterine device, or Norplant for at least 28 days prior to the start of treatment period, or used barrier methods consistently, at least 14 days before study cream administration; b) had a normal menstrual cycle for the month prior to the start of treatment; c) have a negative urine pregnancy test result upon entry into the study; d) agree to use a medically accepted form of birth control throughout the study period.
