Ragweed pollen by month in Oklahoma City
How ragweed usually runs across the year. The current month is outlined.
Managing ragweed season in Oklahoma City
If ragweed is your trigger, start a daily antihistamine like cetirizine (Zyrtec) or loratadine (Claritin) a week or two before the September 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 Oklahoma can test whether ragweed is really what you react to and talk through longer-term options like allergy shots.
