AZT
AZT
AZT is a medicine used to treat HIV. It is not a vaccine. Sometimes HIV drugs can be used before exposure to the virus and reduce the risk of infection. AZT is commonly used by HIV-positive women during pregnancy to prevent passing HIV to their babies. The new born babies also use a small dose of AZT afterwards as an additional protection. The best way for women to use AZT in this way is in a combination with at least two other HIV drugs.
