A member asked:
I am gonna try allegra (fexofenadine) for allergies. i always worry about side effect. how common is it for allegra (fexofenadine) to cause breathing problems?
4 doctors weighed in across 2 answers
Not common: Medication is quite safe. Sudafed on the other hand, ( that I see in your profile you are taking) should be used very cautiously as it can cause problems with hypertension and arrhythmias if not supervised appropriately.
