What are Zidovudine, ZDV tablets?

ZIDOVUDINE, ZDV (AZT or Retrovir®) is an antiviral drug called a nucleoside reverse transcriptase inhibitor or NRTI. Zidovudine is used to treat human immunodeficiency virus (HIV) infection. Zidovudine may reduce the amount of HIV in the blood and increase the number of CD4 cells (T-cells) in the blood. Zidovudine is used with other drugs to treat the HIV virus. Zidovudine will not cure or prevent HIV infection or AIDS. You may still develop other infections or conditions associated with HIV. Generic zidovudine tablets are available.

Zidovudine can cause blood problems. This can mean slow healing and a risk of infection. Try to avoid cutting or injuring yourself. Problems can arise if you need dental work, and in the day to day care of your teeth. Try to avoid damage to your teeth and gums when you brush or floss your teeth. Tell your dentist you are taking zidovudine.

Zidovudine will not cure HIV and you can still get other illnesses or complications associated with your disease. Taking zidovudine does not reduce the risk of passing HIV infection to others through sexual or blood contact. It is best to avoid sexual contact so that you do not spread the disease to others. For any sexual contact, use a condom. Be careful about cuts, abrasions and other possible sources of blood contact. Never share a needle or syringe with anyone.
