Is Telaprevir safe while breastfeeding?

Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Telaprevir. The text below is quoted from that source — it is not our own verdict.

Summary of use during breastfeeding

Telaprevir is no longer marketed in the United States and has not been studied in nursing mothers. Because it must be used with ribavirin and peginterferon alfa, it is not considered a good choice during breastfeeding. When it was marketed, the manufacturer recommended that mothers taking telaprevir not breastfeed their infants.

Alternatives LactMed lists

“No published information” means the studies do not exist yet — not that Telaprevir is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
