Hello,
I understand your concern about taking Cetirizine while breastfeeding. It's good that you're seeking advice.
Cetirizine is generally considered to be of low risk during breastfeeding. Very small amounts may pass into breast milk, but it's not typically expected to cause harm to a breastfed infant, especially if the baby is older than 2 months and not premature or unwell.
Next Steps
Given your history of severe allergic rhinitis and the frequency of your current symptoms, managing your allergies is important for your well-being. So I recommend consulting with your treating doctor
Health Tips
In the meantime, continue to observe your baby closely.
Hope this helps!
Best regards,
