Is Certolizumab Pegol safe while breastfeeding?
Here is what NIH LactMed, the U.S. National Library of Medicine's authority on medicines and breastfeeding, reports about Certolizumab Pegol. This is a summary of that source — not our own verdict.
Effects on the breastfed infant
Eight women who received certolizumab pegol during pregnancy and postpartum breastfed (extent not stated) their infants. No mention was made of side effects in the infants.[ 13 ] Seventeen mothers received certolizumab pegol for an inflammatory condition and breastfed their infants. During a study period starting at least 6 weeks postpartum and after at least 3 doses of certolizumab pegol, 8 of the infants experienced 11 adverse effects. None of the infants had any unusual or serious adverse reactions attributed to the drug and all effects were consistent with events typically experienced by infants of the same age, such as upper respiratory infection, Candida infection, or vomiting.[ 16 ] In a multi-center study of women with inflammatory bowel disease in pregnancy (the PIANO registry), 54 women received certolizumab pegol while breastfeeding their infants. Among those who received certolizumab or another biologic agent while breastfeeding, infant growth, development or infection rate was no different from infants whose mothers received no treatment. An additional 67 women received a biologic agent plus a thiopurine. Infant outcomes were similar in this group.[ 15 ] Six women being treated with certolizumab pegol for uveitis during pregnancy and postpartum breastfed their infants (extent not sated). One of the mothers also took hydroxychloroquine. In 6 months of follow-up, no infants had any infections, and all had inactivated vaccines specified in the Spanish national immunization program (hepatitis B, diphtheria, tetanus and acellular pertussis [DTaP], inactivated poliovirus, Haemophilus influenzae type B conjugate, pneumococcal conjugate and meningococcal C conjugate). One of the infants also received rotavirus vaccine. No complications were seen with any of the vaccines.[ 17 ] Three women were treated with certolizumab, two during pregnancy and breastfeeding and one during breastfeeding alone. Infant follow-up at 6, 18 and 32 months, respectively, found no adve

Levels in milk
Maternal Levels. One woman received certolizumab pegol 400 mg by subcutaneous injection every 4 weeks during pregnancy and postpartum. The last dose during pregnancy was 1 week prior to delivery. Breastmilk samples were collected 1 and 2 weeks postpartum and 4 hours, 3 days and 6 days after the first postpartum dose which was given at 3 weeks postpartum. Certolizumab was undetectable ( 410 mcg/L) in all 5 samples.[ 13 ] Two women were receiving certolizumab pegol 200 mg every two weeks. Certolizumab was undetectable ( 0.6 mg/L) in breastmilk one hour after the dose in both women and 4 hours after the dose in one of them.[ 14 ] Seventeen nursing mothers who were taking certolizumab pegol for an inflammatory condition and were at least 6 weeks postpartum had certolizumab measured in their breastmilk at least 8 times over a dosage interval. The maternal dose was 200 mg every 2 weeks in 16 women and 400 mg every 4 weeks in another. Out of 137 breastmilk samples, 77 had no detectable certolizumab and 4 mothers had no detectable ( 32 mcg/L) certolizumab in milk at any time point, including the mother who received the 400 mg dose. Of the 13 other mothers, the highest concentrations found were 76 mcg/L, which was found in one woman at 6 and 8 days after the dose, and 65 and 66 mcg/L in another at 4 and 6 days after the dose, respectively. All other mothers with detectable certolizumab had milk levels that were less than 64 mcg/L. The median time of peak milk levels was 5.05 days (range 2.9 to 11.9 days). The estimated average daily infant dose ranged from 0 to 0.0104 mg/kg daily. No measurable levels of total polyethylene glycol were detected in 134 of 137 breast milk samples; 3 samples had indeterminate results upon retesting.[ 2 ] In a multi-center study of women with inflammatory bowel disease in pregnancy (the PIANO registry), 13 women receiving certolizumab pegol provided milk samples at 1, 12, 24, and 48 hours after drug administration. Some also provided samples at 7
