<meta name="description" content="Lopinavir appears in breastmilk in low levels and can be found in the serum of some breastfed infants. Although lopinavir has been associated with impaired adrenal gland function when given directly to infants, the effect is dose related.[1] No adverse infant effects have been clearly caused by the small amounts of lopinavir in breastmilk. Achieving and maintaining viral suppression with antiretroviral therapy decreases breastfeeding transmission risk to less than 1%, but not zero. Individuals with HIV who are on antiretroviral therapy with a sustained undetectable viral load and who choose to breastfeed should be supported in this decision. If a viral load is not suppressed, banked pasteurized donor milk or formula is recommended.[2,3]">

Although lopinavir has been associated with impaired adrenal gland function when given directly to infants, the effect is dose related.[<a class="bibr" href="#LM659.REF.1" rid="LM659.REF.1">1</a>] No adverse infant effects have been clearly caused by the small amounts of lopinavir in breastmilk. Achieving and maintaining viral suppression with antiretroviral therapy decreases breastfeeding transmission risk to less than 1%, but not zero. Individuals with HIV who are on antiretroviral therapy with a sustained undetectable viral load and who choose to breastfeed should be supported in this decision. If a viral load is not suppressed, banked pasteurized donor milk or formula is recommended.[<a class="bibr" href="#LM659.REF.2" rid="LM659.REF.2">2</a>,<a class="bibr" href="#LM659.REF.3" rid="LM659.REF.3">3</a>]</p><p>Ritonavir used as a booster has been studied in several studies of breastfeeding mothers. It is excreted into milk in measurable concentrations and low levels can be found in the blood of some breastfed infants. No reports of adverse reactions in breastfed infants have been reported.
