A member asked:

Is it possible to become tolerant to 0.1% patanol (olopatadine) allergy eye-drops?

Yes: Topical antihistamine agents are generally very effective for treatment of seasonal allergy eye conditions. However, as the season progresses, they often lose their effect. That does not make this "bad" medicine; rather, it probably attests to the severity of allergies that you have.
