I have had allergies for a number of years, but I need help. I have been recently using allergy relief, but there are 2 different types. One Is loratadine and the other is Diphenhydramine hydrochloride. The hydrochloride is 25 mg and the loratadine is 10 mg. What is the difference between loratadine and diphenhydramine hydrochloride? I'm guessing that the loratadine is more for allergies, but I'm not sure. It would also help if you could tell me the different ways these treat your allergies. If not, it's ok, it's ok, I was just wondering. But please help when you find time. Thank you
