Can you take antihistamines while pregnant?
Yes, you can take antihistamines while pregnant, and most research suggests they are safe. Doctors generally recommend second-generation antihistamines like cetirizine and loratadine, which are non-sedating and don't cross the blood-brain barrier. It's always best to speak with your doctor before starting any antihistamine during pregnancy to ensure it's the right choice for you.
Key points:
- Cetirizine and loratadine are the preferred antihistamines in pregnancy as they have the most safety data available
- First-generation antihistamines like diphenhydramine are also considered safe, though second-generation options are generally recommended
- Some antihistamines like fexofenadine are not usually recommended in pregnancy because there is limited safety information
- All antihistamines are safe to use while breastfeeding, as only minimal amounts pass into breast milk
