Can you take celecoxib while breastfeeding?
What LactMed says
The National Library of Medicine’s own summary, quoted in full. We do not write a verdict of our own on this question, and we do not compress theirs into a label.
Because of the low levels of celecoxib in breastmilk, amounts ingested by the infant are small and would not be expected to cause any adverse effects in breastfed infants. No special precautions are required.
Quoted from Celecoxib — Drugs and Lactation Database (LactMed®), National Institute of Child Health and Human Development, revised May 15, 2025.
What LactMed would consider instead
LactMed ends this record by naming the drugs it would consider in place of celecoxib. Whether any of them fits depends on what you are treating — this is the database’s list, not a recommendation from us.
How much celecoxib gets into breastmilk
Maternal Levels. Milk celecoxib levels were measured in one mother taking 100 mg orally twice daily. At 4.75 hours after the fourth dose, milk levels were 101 and 133 mcg/L from her right and left breasts, respectively. A second peak level of about 30 mcg/L occurred in milk from the right breast about 35 hours after the last dose. The average half-life in the milk was 5.1 hours. The authors estimated that a fully breastfed infant would receive a maximum dose of 40 mcg/kg daily.
Three mothers, averaging 12 months postpartum, who had been taking oral celecoxib 200 mg daily (average 3.27 mg/kg daily) for several weeks had milk celecoxib levels measured at several times during a 24-hour period. Peak milk levels averaged 139 mcg/L at 2 hours after the dose. By 12 hours after the dose, celecoxib was undetectable (<10 mcg/L) in milk. Two other mothers were given a single oral dose of celecoxib 200 mg. Breastmilk and maternal serum were collected periodically over an 8-hour period. Peak milk levels were 170 mcg/L at 4 hours after the dose in one woman and 269 mcg/L at 2 hours after the dose in the other. Based on data from these 5 women, an exclusively breastfed infant would receive an estimated 9.8 mcg/kg daily or 0.3% of the maternal weight-adjusted dosage.
Six women averaging 11 months postpartum (range 6.5 to 15 months) were given a single 200 mg dose of celecoxib orally. Milk samples were collected for 48 hours after the dose. A median peak milk level of 200 mcg/L (range 70 to 330 mcg/L) occurred 2 to 4 hours after the dose. The authors calculated that a fully breastfed infant would receive a median daily dosage of 13 mcg/kg (range 11 to 210 mcg/kg) or 0.23% of the maternal weight-adjusted dosage.
Thirteen nonlactating women took celecoxib 200 or 400 mg twice daily for 2 weeks followed by collection of nipple aspirate fluid. Two women taking 200 mg twice daily had celecoxib concentrations of 1.2 and 1.5 mg/L; 2 women taking 400 mg twice daily had celecoxib concentrations of 0.53 and 8.4 mg/L in the aspirate. Celecoxib was undetectable (lower limit of assay not stated) in the in nipple aspirate fluid of the other 9 women. Collection times with respect to the doses were not stated.
Infant Levels. Two breastfed infants whose mothers had been taking celecoxib 200 mg orally twice daily for many weeks, had blood samples taken 4 hours after a maternal dose. The infants were 17 and 22 months of age and were breastfed on demand every 3 to 4 hours during the day and once at night. Celecoxib was undetectable (<10 mcg/L) in the plasma of these infants.
What has been seen in breastfed infants
No infant side effects were noted by the mothers of 2 infants aged 17 and 22 months who were breastfed during long-term maternal use of celecoxib 200 mg daily.

Frequently asked questions
Can you take celecoxib while breastfeeding?
What the NIH's Drugs and Lactation Database says about Celecoxib while breastfeeding — quoted in full. The full record is quoted on this page, and the decision is one to make with the person who prescribed it — LactMed itself states it is not a substitute for professional judgement.
What can I take instead of celecoxib while breastfeeding?
LactMed lists Acetaminophen, Flurbiprofen, Ibuprofen, Indomethacin, Piroxicam as alternate drugs to consider. That is the database's own list for this drug — whether any of them suits you depends on what you are treating.
Does celecoxib pass into breastmilk?
LactMed's measured drug levels for celecoxib are quoted in full on this page, under "How much gets into breastmilk".
Do I need to pump and dump after taking celecoxib?
LactMed does not frame its records that way — it reports measured drug levels in milk and what has been observed in breastfed infants, which is what this page quotes. "Pump and dump" advice for a specific drug and dose should come from your clinician or a pharmacist, not from a general rule.
