Good day, is allergex safe while breastfeeding. my baby is 3 months old?

Likely ok: There are no human data but is is suggested that it is safe for short term symptoms management. Ok to use for a day or 2.

No: Drugs like Allergex are excreted into the breast milk, meaning that if you are breastfeeding while taking it, your child may be exposed to it as well. Other drugs that do the same thing but that produce fewer side effects, like loratadine or fexofenadine, are safer alternatives and are recommended by the American Academy of Pediatrics for breastfeeding mothers who wish to take antihistamines.
