Can I breastfeed while taking Cosentyx (secukinumab)?
Cosentyx (secukinumab) is a monoclonal antibody. Like many large antibody drugs, only very small amounts are expected to pass into breast milk, and any that do would likely be broken down in the baby’s gut rather than absorbed in meaningful amounts.
However, the decision to breastfeed while using Cosentyx should be individualized with the prescribing clinician, especially for newborns or premature infants.
What do the sources say about Cosentyx and breastfeeding safety?
Drug safety language on biologics in pregnancy and breastfeeding usually focuses on limited real-world data plus the drug’s expected low transfer into milk for large protein molecules. Because your question is specifically “Cosentyx breastfeeding,” the most important next step is to check the latest prescribing information or clinician resources for current guidance for your dose and your baby’s age.
What factors change the advice?
Clinicians commonly weigh:
- Baby’s age (newborns and premature infants are treated more cautiously)
- Whether the mother needs Cosentyx to control active disease (stopping can worsen flare risk)
- Any history of infections in the infant
- Whether the mother is on other immunomodulating medicines with Cosentyx (risk profile can change)
Are there safer alternatives or timing strategies?
Some people ask whether they can “pump and discard” or time doses to reduce exposure. For biologics like secukinumab, because transfer into milk is expected to be low and antibodies are proteins that get degraded in the infant GI tract, these timing strategies usually have limited evidence behind them. The best approach is typically shared decision-making rather than a rigid pumping/discard plan.
What about infant immunizations if mom is breastfeeding on Cosentyx?
Breastfeeding itself generally does not change routine vaccination schedules. Still, if a baby is exposed to additional medications through pregnancy or if there are concerns about immune effects, clinicians may want to coordinate with the pediatrician about vaccinations and infection monitoring.
