Pregnancy: There are no or limited data from the use of lanadelumab in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive or developmental toxicity (see Pharmacology: Toxicology: Preclinical safety data under Actions). As a precautionary measure, it is preferable to avoid the use of lanadelumab during pregnancy.
Breast-feeding: It is unknown whether lanadelumab is excreted in human milk. Human IgGs are known to be excreted in breast milk during the first few days after birth, which is decreasing to low concentrations soon afterwards; consequently, a risk to the breast-fed child cannot be excluded during this short period. Afterwards, lanadelumab could be used during breast-feeding if clinically needed.
Fertility: Lanadelumab's effect on fertility has not been evaluated in humans. Lanadelumab had no effect on male or female fertility in cynomolgus monkeys (see Pharmacology: Toxicology: Preclinical safety data under Actions).
