Telaprevir and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for telaprevir: levels in milk, effects in breastfed infants, and the drugs it would consider insteadTelaprevir 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.

What people report to the FDA about telaprevir
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 14,683 reports naming telaprevir, and the FDA flagged 53% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- fatigue3,003 reports
- anaemia2,820 reports
- nausea2,310 reports
- rash2,281 reports
- pruritus1,664 reports
- headache1,197 reports
- white blood cell count decreased1,147 reports
- decreased appetite1,146 reports
Read these as a signal, not a rate. A report does not mean telaprevir caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
Can you take telaprevir with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run telaprevir against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does telaprevir come in?
Across the brands we track, telaprevir is currently marketed as tablet, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic telaprevir?
We do not currently list a generic-labelled telaprevir product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
