lamivudine and zidovudine, Combivir (cont.)

Pharmacy Author:
Medical and Pharmacy Editor:

The effectiveness of either lamivudine or zidovudine when used alone may decrease as the HIV virus develops resistance to the effects of the individual drugs. By combining lamivudine and zidovudine, it is more difficult for the HIV virus to develop resistance to therapy since it must develop resistance to both drugs. As a result, Combivir is more effective than lamivudine or zidovudine alone. Combivir does not kill existing HIV virus, and it is not a cure for HIV. Combivir was approved by the FDA in September 1997.
