Summary
Conivaptan inhibits CYP3A4, but zidovudine is cleared mainly by glucuronidation with only minor CYP involvement. A clinically meaningful rise in zidovudine levels is therefore unlikely.
What this interaction means in plain words
Conivaptan and Zidovudine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Conivaptan inhibits CYP3A4, a minor pathway for zidovudine elimination.
What to do
No dose adjustment is needed; monitor routinely for zidovudine adverse effects such as anemia and neutropenia.
