How does etanercept work?
Etanercept is an antibody that blocks the production of certain inflammatory chemicals in the body that cause autoimmune disease.
If I am taking etanercept, can it harm my baby?
Etanercept does cross the human placenta to reach the developing baby. One small study found that maternal exposure to etanercept during conception or the first trimester, or by paternal exposure to the medication were not associated with an increased risk of birth defects. A majority of available studies are case reports and some large registry studies; there is no consistent pattern of birth defects that can be directly connected to etanercept therapy during pregnancy. Some studies have suggested that etanercept is associated with an increased risk of prematurity and low birth weight, but no correlation has been proven. The effect of etanercept on long-term infant immune function is unknown; administration of live vaccines is typically delayed in infants exposed to in utero etanercept. Estimates of etanercept concentration in newborn infants exposed to the medication in the womb range from 3% to 32% of the maternal concentration. There is a study that collects data from pregnancies exposed to etanercept: OTIS Enbrel Pregnancy Registry.
If I am taking etanercept and become pregnant, what should I do?
Etanercept should only be used for treatment in pregnant women who need the medication and in whom the benefit will outweigh the risk to the developing baby. There is also some risk to the developing babies of women with untreated immune diseases such as rheumatoid arthritis.
If I am taking etanercept, can I safely breastfeed my baby?
Etanercept can be transferred through breast milk in small quantities. The manufacturer of etanercept recommends weighing the risks versus benefits to the infant and mother before using this medication while breastfeeding. It is important to talk to your doctor to decide if you should continue on etanercept during breastfeeding.
If I am taking etanercept, will it be more difficult to get pregnant?
The small amount of evidence available suggests that etanercept has no effect on male or female fertility.
If I am taking etanercept, what should I know?
Although etanercept may be associated with a small risk of side effects in the developing baby, serious birth defects are not increased with its use during pregnancy. It is always important to speak with your doctor before continuing this medication during conception or pregnancy.
