5 Warnings and Precautions

5.2 Lactic Acidosis and Severe Hepatomegaly with Steatosis

(Additions and/or revisions are underlined)

Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues, including EPIVIR. A majority of these cases have been in women. Female sex and obesity may be risk factors for the development of lactic acidosis and severe hepatomegaly with steatosis in patients treated with antiretroviral nucleoside analogues. Treatment with EPIVIR should be suspended in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity, which may include hepatomegaly and steatosis even in the absence of marked transaminase elevations.

Risk Summary

The Centers for Disease Control and Prevention recommends that HIV-1-infected mothers in the United States not breastfeed their infants to avoid risking postnatal transmission of HIV-1 infection. Lamivudine is present in human milk. There is no information on the effects of lamivudine on the breastfed infant or the effects of the drugs on milk production. Because of the potential for (1) HIV-1 transmission (in HIV-negative infants), (2) developing viral resistance (in HIV-positive infants), and (3) adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving EPIVIR.

5 Warnings and Precautions

Lower Virologic Suppression Rates and Increased Risk of Viral Resistance with Oral Solution

  • Pediatric subjects who received EPIVIR oral solution concomitantly with other antiretroviral oral solutions at any time in the ARROW trial had lower rates of virologic suppression, lower plasma lamivudine exposure, and developed viral resistance more frequently than those receiving EPIVIR tablets.
  • EPIVIR scored tablet is the preferred formulation for HIV-1-infected pediatric patients who weigh at least 14 kg and for whom a solid dosage form is appropriate. Consider more frequent monitoring of HIV-1 viral load when treating with EPIVIR oral solution.

8 Use in Specific Populations

Pediatric Use

  • EPIVIR scored tablet is the preferred formulation for HIV-1-infected pediatric patients who weigh at least 14 kg and for whom a solid dosage form is appropriate because pediatric subjects who received EPIVIR oral solution had lower rates of virologic suppression, lower plasma lamivudine exposure, and developed viral resistance more frequently than those receiving EPIVIR tablets in the ARROW trial (addition).

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PCI - Immune Reconstitution Syndrome (revised)

  • Advise patients to inform their healthcare provider immediately of any signs and symptoms of infection as inflammation from previous infection may occur soon after combination antiretroviral therapy, including when EPIVIR is started.

PCI - Lactation

  • Instruct women with HIV-1 infection not to breastfeed because HIV-1 can be passed to the baby in the breast milk.

PCI - Lactic Acidosis/Hepatomegaly (revised)

  • Advise patients that lactic acidosis and severe hepatomegaly with steatosis have been reported with use of nucleoside analogues and other antiretrovirals. Advise patients to stop taking EPIVIR if they develop clinical symptoms suggestive of lactic acidosis or pronounced hepatotoxicity.

PCI - Missed Dosage

  • Instruct patients that if they miss a dose of EPIVIR, to take it as soon as they remember. Advise patients not to double their next dose or take more than the prescribed dose.

PCI - Pregnancy Registry

  • Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to EPIVIR during pregnancy.
