What type of anemia does zidovudine cause?

AZT can be toxic to the bone marrow—the soft tissue inside bones where blood cells are made. As a result, AZT can cause anemia (lowered red blood cell levels) and neutropenia (lowered neutrophil or white blood cell counts).

Did AZT save lives?

Mortality rates for people taking AZT were staggeringly lower than those taking the placebo; there had been 19 deaths in the placebo group of 137 people, but only one in the AZT group of 145. Those on AZT also had a decreased number of opportunistic infections and showed improvement in weight gain and T4 cell counts.

Why is AZT toxic to humans?
