One Month Dual Antiretroviral Prophylaxis to Prevent Resistance Mutations in Mothers Exposed to Single Dose Nevirapine

Summary

The purpose of this study is to determine whether providing zidovudine (ZDV) and didanosine (ddI) during labor and for one month postpartum can reduce the selection of nevirapine (NVP) resistance mutations postpartum in women who received a single dose of nevirapine during labor and standard ZDV prophylaxis for the prevention of mother to child transmission of HIV.
