Olaratumab and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for olaratumab: levels in milk, effects in breastfed infants, and the drugs it would consider insteadOlaratumab is no longer marketed in the United States. No information is available on the clinical use of olaratumab during breastfeeding. Because olaratumab is a large protein molecule with a molecular weight of about 154,000 Da, the amount in milk is likely to be very low. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. However, olaratumab is given with doxorubicin. The manufacturer recommends that women should not breastfeed during treatment with olaratumab and for 3 months following the last dose.

What people report to the FDA about olaratumab
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 268 reports naming olaratumab, and the FDA flagged 97% 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:
- febrile neutropenia47 reports
- neutropenia26 reports
- malignant neoplasm progression24 reports
- diarrhoea17 reports
- anaemia15 reports
- neoplasm recurrence15 reports
- dyspnoea14 reports
- infusion related reaction13 reports
Read these as a signal, not a rate. A report does not mean olaratumab 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 olaratumab 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 olaratumab 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 olaratumab come in?
Across the brands we track, olaratumab is currently marketed as injectable, 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 olaratumab?
We do not currently list a generic-labelled olaratumab 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.
