Avonex and Breastfeeding: What Does the Research Say?
No studies have been conducted on whether Avonex passes through breast milk. However, Avonex is a delicate molecule that cannot be taken by mouth (it must be injected), since the
digestive system would destroy the molecule. Therefore, even if Avonex passes through breast milk, it would be destroyed and inactivated by the digestive system of the infant. However, since no studies have been performed, it is impossible to predict exactly what effects Avonex may cause in a breastfed infant.
