Is Celecoxib safe while breastfeeding?
Here is what NIH LactMed, the U.S. National Library of Medicine's authority on medicines and breastfeeding, reports about Celecoxib. This is a summary of that source — not our own verdict.
Effects on the breastfed infant
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.[ 3 ]

Levels in milk
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.[ 2 ] 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.[ 3 ] 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.[ 4 ] 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 celecox
