8 Use in Specific Populations

Pregnancy

Risk Summary

There are no available data on ALTABAX use in pregnant women to inform any drug associated risk for major birth defects, miscarriage or adverse maternal or fetal outcomes. Retapamulin is negligibly absorbed systemically following topical administration and maternal use is not expected to result in fetal exposure to the retapamulin.

Animal reproduction studies were not conducted with ALTABAX. However, in animal studies where retapamulin was administered by oral gavage or intravenous infusion to pregnant rats and rabbits, respectively, during organogenesis, maternal toxicity was seen at doses greater than or equal to 150 mg/kg/day and 7.2 mg/kg/day (8-fold the maximum achievable human exposure based on AUC) for oral and intravenous routes, respectively. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.  In the U.S. general population the background risk of major birth defects in clinically recognized pregnancies is 2% to 4% and of miscarriage is 15% to 20%, respectively.

Lactation

Risk Summary

There are no data available on the presence of retapamulin in human milk, its effects on the breastfed infant or its effects on milk production. However, breastfeeding is not expected to result in exposure of the child to the drug due to the negligible systemic absorption of retapamulin in humans following topical administration of ALTABAX.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ALTABAX and any potential adverse effects on the breastfed infant from ALTABAX or from the underlying maternal condition.
