Although no studies have been done on Xyzal and breastfeeding, it is assumed that the drug passes through breast milk. This is because Zyrtec (a medication that is chemically similar) does pass through breast milk and may cause slow weight gain in the nursing baby. If you decide to take Xyzal while breastfeeding, be sure to watch for any side effects in your child.

Xyzal and Breastfeeding: What Does the Research Say?
No studies have been done to see if Xyzal passes through breast milk in humans. However, it does pass through breast milk in animals. It is assumed that Xyzal passes through breast milk in humans because Zyrtec® (cetirizine), which is chemically similar to Xyzal, passes through breast milk. When Xyzal was given to mice that were breastfeeding, it caused slow weight gain in the baby mice. If your healthcare provider recommends taking Xyzal while breastfeeding, be sure to watch for any side effects in your child, including slow weight gain.
