Retrovir

Retrovir (zidovudine) is a nucleoside reverse transcriptase inhibitor (NRTI) that works by inhibiting the replication of HIV. It is used as part of combination antiretroviral therapy (ART) to manage HIV infection and to prevent mother-to-child transmission of HIV during pregnancy, labor, and delivery.

Dosage by Body Weight

Dosage must be prescribed and monitored by an infectious disease specialist. For adults, the standard dose is 300 mg twice daily. Pediatric dosing is highly individualized, calculated based on body weight or body surface area, and is typically administered twice daily.
