A member asked:
Is there such thing as antihistamine resistance? seems like it becomes less effective the more i take it.

Drug Resistance: Tachyphylaxis: Rapidly decreasing response to a drug or physiologically active agent after administration of a few doses. Try a different antihistamine and that should work for you.

Possibly: Occasionally this happens. Stopping the antihistamine for a few days, and then switching to a new one may help.
