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