Betaseron and Breastfeeding
The risks of using Betaseron (interferon beta-1b) while breastfeeding are currently unknown. Since Betaseron is a protein that can be destroyed by the digestive system if taken by mouth, it is also likely to be destroyed by the infant's digestive system (if it does pass through breast milk). Talk to your healthcare provider about Betaseron and breastfeeding to further discuss the benefits and possible risks.
Betaseron® (interferon beta-1b) is a prescription medication approved for the treatment of multiple sclerosis. Because the risks of using Betaseron while breastfeeding are not currently known, the manufacturer of Betaseron does not recommend taking the drug while breastfeeding. Therefore, be sure to talk with your healthcare provider if you take Betaseron and are breastfeeding or thinking of starting.
No studies have been conducted on whether Betaseron passes through breast milk. However, Betaseron is a delicate protein that cannot be taken by mouth. Instead, it must be taken by injection, since the digestive system would destroy the protein. Therefore, even if Betaseron passes through breast milk, it would probably be destroyed (and therefore inactivated) by the infant's digestive system. However, since no studies have been performed, it is impossible to predict exactly what effects (if any) Betaseron may cause in a breastfed infant.
You and your healthcare provider must consider the benefits of Betaseron to you, the benefits of breastfeeding for your baby, and the possible unknown risks of Betaseron to your baby.
