My sinus mucus swelled up so bad i could hardly breath
and my face turned bright red. I did not take it again after that. I tried just general
Benadryl and had the same reaction. Red face hard to breath through the nose. I was recently prescribed Allegra and am nervous to take it as it looks like it has a lot of the same medication as benadryl but stronger. Are these medications the same?
