Is INTERFERON BETA 1-B-INJECTION safe to take if I'm pregnant or breastfeeding?

  • Use of interferon beta-1b has not been adequately evaluated in pregnant women. Due to the lack of conclusive safety data, interferon beta-1b should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus.
  • It is not known if interferon beta-1b is excreted in breast milk. As many drugs enter breast milk and can potentially cause harm to the nursing infant, interferon beta-1b should be used cautiously in nursing mothers.
