    Pregnancy and Lactation


    Eptinezumab is contraindicated during pregnancy.

    Use of eptinezumab during pregnancy is contraindicated by the manufacturer. At the time of writing, there is limited published information regarding the use of eptinezumab during pregnancy. Potential risks are unknown, however human IgG is known to cross the placenta and therefore eptinezumab is expected to cross the placenta and transfer to the foetus.


    Use eptinezumab with caution during breastfeeding.

    The manufacturer does not recommend breastfeeding whilst taking eptinezumab. During the first few days after birth, human IgG is known to be excreted in breast milk and therefore a risk to the breastfed infant cannot be excluded during this period. Following this period, the use of eptinezumab during breastfeeding should only be considered if clinically necessary. LactMed (2020) notes that due to the large molecular weight of eptinezumab (143,000 Da) the amount of eptinezumab in breast milk is expected to be low and absorption unlikely due to the likelihood of eptinezumab being destroyed in the infants gastrointestinal tract.

    Side Effects
