Pregnancy and Lactation
Fremanezumab is contraindicated during pregnancy.
The manufacturer recommends avoiding fremanezumab during pregnancy.
At the time of writing there is limited data available regarding fremanezumab in pregnancy, animal studies do not indicate harmful effects with respect to reproductive toxicity.
Use fremanezumab with caution during breastfeeding.
The manufacturer advises caution if fremanezumab is used when breastfeeding. The presence of fremanezumab in human breast milk is unknown. However, human IgG is excreted in breast milk during the first days after birth, which is decreasing to low concentrations soon afterwards, consequently, a risk to the infant cannot be excluded during this short period. Afterwards, fremanezumab could be considered during breastfeeding only if clinically needed. Effects on breastfed infants are unknown.
LactMed (2020) indicates that since fremanezumab is a large protein molecule with a molecular weight of about 148,000, the amount in breast milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract.
