Erelzi and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
There are limited studies that have been done in humans with Erelzi. In animal studies, pregnant animals were given this medication, and revealed no evidence of harm to the babies due to etanercept. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Erelzi and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
There are limited studies that have been done in humans while breastfeeding. Some data shows that etanercept is present in low levels in human milk and minimally absorbed by a breastfed infant. There are no data on the effects on the breastfed infant, or the effects on milk production.
Many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if you will stop nursing or stop the medication.
