Does taking antiallergy medication during breastfeeding have a significant impact on the baby?

Patient's question:

No

Doctor's answer:

During lactation, mothers are advised to avoid medication as much as possible to prevent the drug from metabolizing through breast milk and affecting the baby.
However, the specific medication and dosage also need to be considered. Antihistamines have a relatively minor impact on the baby, but if the medication needs to be taken for an extended period, breastfeeding should be temporarily paused.
