Kaletra (lopinavir/ritonavir): Serious Health Problems in Premature Babies

FDA notified healthcare professionals of serious health problems that have been reported in premature babies receiving Kaletra (lopinavir/ritonavir) oral solution. Kaletra oral solution contains the ingredients alcohol and propylene glycol. Premature babies may be at increased risk for health problems because they have a decreased ability to eliminate propylene glycol; this could lead to adverse events such as serious heart, kidney, or breathing problems. Because the consequences of using Kaletra oral solution in babies immediately after birth can be severe or possibly fatal, the label is being revised to include a new warning.

BACKGROUND: Kaletra oral solution is an antiviral medication used in combination with other antiretroviral drugs for the treatment of HIV-1 infection in pediatric patients 14 days of age (whether premature or full term) or older and in adults.

RECOMMENDATION: The use of Kaletra oral solution should be avoided in premature babies until 14 days after their due date, or in full-term babies younger than 14 days of age unless a healthcare professional believes that the benefit of using Kaletra oral solution to treat HIV infection immediately after birth outweighs the potential risks. In such cases, FDA strongly recommends monitoring for increases in serum osmolality, serum creatinine, and other signs of toxicity.
