Managing maple season in Philadelphia

If maple is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the March to April peak, rather than waiting for symptoms. Keep windows closed on high-count mornings, shower and change clothes after time outside, and run the AC on recirculate in the car.

When symptoms don't ease with over-the-counter medicine, an allergist in Pennsylvania can test whether maple is really what you react to and talk through longer-term options like allergy shots.
