Contradicting earlier findings, a new study says that the drug nevirapine does prevent the spread of HIV from mother to child in repeat pregnancies.
The study of 198 Ugandan women found that HIV transmission was blocked during second pregnancies for those on the drug who had also taken it for their first pregnancy, the Associated Press reported.

Previous studies suggested that HIV developed resistance to nevirapine, an inexpensive and easy-to-use drug that has become a vital part of the effort to prevent mother-to-child HIV transmission in poor nations.
Mothers are given the drug when they go into labour and newborns receive the medication in syrup form within 72 hours of birth. It's believed the drug may reduce HIV transmission risk by half.
"Based on these findings, we believe nevirapine in repeat pregnancies remains an effective option in these resource-limited countries," researcher Dr Michael Thigpen, a medical epidemiologist with the US Centres for Disease Control and Prevention, told the AP. – (HealthDayNews)
