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