A 35-year-old member asked:

Would it be possible that a pregnant woman take benadryl/antihistamine to treat an allergic reaction or help allergy induced asthma?

Yes: Antihistamines are generally safe in pregnancy; allowing an allergic reaction to progress can cause more harm to the baby than the antihistamines can.
Dr. Steven Machtinger

Yes & No: Benadryl (diphenhydramine) is considered safe in pregnancy & may be used to treat allergic conditions like allergic rhinitis or hives. Antihistamines like Benadryl are not effective for itching not associated with a rash. This can be due to pregnancy-related liver problems. Talk to your OB about that. Benadryl is also not effective for asthma. There are safe asthma drugs to use while pregnant.
