Antiretroviral medications

The goals of antiretroviral administration during pregnancy are to reduce the risk of transmission of HIV from mother to child, to slow maternal disease progression, and to reduce the risks of maternal opportunistic infection and death. It is important to choose medications that are as safe as possible for the mother and the fetus, and are effective at decreasing the total viral load. Certain antiretroviral drugs carry a risk of toxicity for the fetus. However, the overall benefits of an effective ART regimen outweigh the risks and all women are encouraged to use ART for the duration of their pregnancy. It is important to note that the associations between birth defects and antiretroviral drugs are confounded by several important factors that could also contribute to these complications, for example: exposure to folate antagonists, nutritional and folate status, and tobacco, alcohol, and drug use during pregnancy.
