HIV infection. Prevention of maternal-fetal HIV transmission.
Adult Dose for RETROVIR IV:
Give by IV infusion over 1 hour; use only until oral therapy can be given. 1mg/kg 5–6 times daily. End-stage renal disease on dialysis: 1mg/kg every 6–8 hours. Vertical transmission, severe anemia and/or neutropenia: see literature.
Suspend if lactic acidosis or hepatotoxicity (eg, hepatomegaly, steatosis) occurs. Monitor for hematologic toxicity; reduce dose or suspend if significant anemia and/or granulocytopenia occurs; transfuse if necessary. Renal or hepatic dysfunction: consider reducing dose. Bone marrow suppression. Risk of liver disease. Women, obesity, prolonged nucleoside exposure, or advanced HIV disease: increased risk of toxicity. Elderly. Pregnancy (Cat.C). Nursing mothers: not recommended.
Avoid stavudine, doxorubicin, ribavirin, other nucleoside analogues, other forms of zidovudine. Caution with other cytotoxic or myelosuppressive drugs (eg, ganciclovir, interferon-alpha, ribavirin). Fluconazole, atovaquone, lamivudine, probenecid, valproic acid, methadone increase zidovudine levels. Monitor phenytoin. May be antagonized by rifampin, ritonavir, nelfinavir. Monitor for treatment-associated toxicities with interferon-alpha with or without ribavirin.
