Right now, there isn’t enough scientific data to say whether Cimzia is safe to use while pregnant. Although, researchers do know that certain autoimmune diseases treated with certolizumab pegol, including Crohn’s disease and rheumatoid arthritis, can affect an expecting parent’s immune health. This impact may increase the risk of adverse outcomes, including preterm birth and low birthweight.Â
Cimzia and Breastfeeding
Limited data suggests that Cimzia may be able to cross into breast milk, but reported concentrations were very low and no adverse effects in infants were reported.
FAQ
Can you take Cimzia while pregnant?
It’s not fully known whether taking Cimzia while pregnant increases the risk of adverse effects for either the parent or the fetus. Some people may decide with their doctors that this medication is the best available option for them, even if they are pregnant or planning to become pregnant.
If someone decides to use Cimzia while pregnant, they are invited to join the Cimzia pregnancy registry so that researchers can learn more about if and how the medication influences pregnancy.
Does Cimzia cross the placenta?
Compared to other TNF inhibitors, certolizumab pegol is reportedly less likely to cross into the placenta during a pregnancy, if at all.
Can you breastfeed on Cimzia?
Breastfeeding individuals may take this drug with their doctor’s supervision if it’s decided that the medication is the best treatment option for them. Limited research indicates that either an extremely minimal amount or no amount of Cimzia crosses into breast milk. If it does, it may not cause any adverse effects in breastfed infants, but this doesn’t mean adverse effects aren’t possible.
