It is not known whether interferon beta-1a passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Some brands of interferon beta-1a contain albumin. Albumin comes from human plasma (part of the blood) which may contain viruses and other infectious agents. Donated plasma is tested and treated to reduce the risk of it containing infectious agents, but there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.
