Conclusions: Fexofenadine at a dose of 360mg is demonstrably free from disruptive effects on aspects of psychomotor and cognitive function in a study where the psychometric assessments have been shown to be sensitive to impairment, as evidenced by the effects of the verum control promethazine 30 mg.
The dose of fexofenadine can be doubled to 360mg twice daily (total daily dose of 720mg). If the maximum dose is reached, it should be maintained for four weeks before deemed treatment failure.

Why do antihistamines stop working? Antihistamines can stop working because your allergies might be getting worse or you might have immune system changes due to aging. You also might not be taking the medication as directed. If you take an antihistamine after being exposed to an allergy trigger, it won't work as well.
Cetirizine is the most potent antihistamine available and has been subjected to more clinical study than any other.
