Zidovudine was the first medicine approved for HIV, and it holds an important place in the history of treatment. It is still available today, although its role has narrowed considerably as newer options have become standard. This guide explains what zidovudine is, where it is used now, and the monitoring a treating doctor carries out.
Zidovudine is commonly abbreviated to AZT, and is sometimes written as ZDV.

Quick Summary / Key Takeaways
|
Zidovudine belongs to the NRTI class covered in the guide to NRTI drugs. It works by interfering with reverse transcriptase, the enzyme HIV uses to copy its genetic material.
For most people beginning treatment today, current guidance points to regimens built around an integrase inhibitor, as described in first-line ART regimens explained.
| Monitoring point | Why it matters |
|---|---|
| Blood counts | Zidovudine can lower red and white cell counts, including anaemia |
| Energy levels | Persistent tiredness may reflect a change in blood counts |
| Liver measures | Reviewed as part of routine follow-up |
| Treatment response | Viral load testing confirms the regimen is working |
These checks are arranged through HIV lab testing.
| Myth | Fact |
|---|---|
| Zidovudine is no longer available. | It remains available and is used in particular situations. |
| Being an older medicine means it does not work. | It is effective, but newer options are generally better tolerated. |
| Blood tests are optional during treatment. | Blood counts are a key monitoring point with zidovudine. |
| Zidovudine can be taken on its own. | It is used as part of a combination regimen. |
| Tiredness is always unrelated to the medicine. | Persistent tiredness may reflect a change in blood counts and should be reviewed. |
| When to Consult a Doctor Medical advice is appropriate before starting or changing zidovudine, where persistent tiredness or breathlessness develops, and where side effects continue beyond the early weeks. A consultation can be arranged through an HIV doctor consultation. |
