Does Loratidine Tablet Cause Excessive Nasal Drainage?

I have Asthma & allergies. I take my shots two twice a week faithfuly. My Asthma however is way under control I never have any asthma attacks ever. I also take Loratidine 10mg. daily. However every night & morning I have ample drainage that makes me cough a lot & have to clear my throat. Should maybe I stop the Loratidine? Could that be causing my drainage?
