id="LM59.Summary_of_Use_during_Lactation"><h3>Summary of Use during Lactation</h3><p>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.[<a class="bibr" href="#LM59.REF.1" rid="LM59.REF.1">1</a>] No special precautions are required.</p></div><div id="LM59.Drug_Levels"><h3>Drug Levels</h3><p><i>Maternal Levels.</i> 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.[<a class="bibr" href="#LM59.REF.2" rid="LM59.REF.2">2</a>]</p><p>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 (&#x0003c;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.[<a class="bibr" href="#LM59.REF.3" rid="LM59.REF.3">3</a>] 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.</p><p>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.[<a class="bibr" href="#LM59.REF.4" rid="LM59.REF.4">4</a>]</p><p>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.

The infants were 17 and 22 months of age and were being breastfed on demand every 3 to 4 hours during the day and once at night.
