Stanford study finds HIV drug can persist in mothers' milk
Stanford: A drug commonly used in the developing world to prevent transmission of HIV from mother to child persists in the breast milk and blood of the mothers, putting them and their babies at risk for developing drug-resistant strains of the virus, according to researchers at the Stanford University School of Medicine.
The researchers found that the drug, nevirapine, stays in the blood and breast milk of the infected mothers for at least two weeks. During that time, the virus has ample opportunity to transform itself into drug-resistant strains of HIV, the human immunodeficiency virus that causes AIDS, which can be very difficult to treat.
