Which uis best for hay fever cetirizine hydrochloride or loratadine?

Both work...: But i tend to prefer Cetirizine because I have had a better personal experience and my patients generally do better with this treatment as well. Of course, if you use Loratadine and it is helping, stick with it.

Both are good: Everyone reacts differently to medicines...Some people like Cetirizine better than loratidine..Others prefer fexofenadine..Or vica versa...
