Question:
I went to the drugstore to find Unisom but but the ingredient is Diphenhydramine HCI, I didn't see any others with doxylamine did I get the wrong one? Not coping well with trying to look after my two-year-old and manage the nausea!

Answer:
You did not get the wrong one, doxylamine is the antihistamine in Diclectin, diphenhydramine is the antihistamine in Unisom. Both of these antihistamines belong to the the same class and are safe to take in pregnancy .
