AID for your airway allergy.

Again, due to the potential danger of airway allergies, the only over-the-counter agent that is available to you is the oral antihistamine. Another non-prescription medication that could be useful is the Asthmanephrin inhaler. This racemic epinephrine spray can temporarily open a constricted, "tight" airway.

I cannot emphasize strongly enough that, if you have airway allergies often synonymous with asthma, your doctor or allergist should frame a program for you to follow. Use of over-the-counter medications for these disorders is ill-advised and dangerous.
