Which is better for my allergic rhinitis? There are so many OTC pills for allergies out there.

Depends............. What is "better"for you is which medication works! i agree that there are many choices out there and only by "trial and error"will you experience what works best to control your symptoms. Diphenhydramine can cause drowsiness and has to be taken every 6-8 hours. Cetirizine can also cause drowsiness and is best taken in the evening. Loratidine and fexofinidine are less and non-drowsy .
