I normally use Piriton, which is an anti-histamine. However, it can have a slight tendency to make you drowsy (although I rarely notice it).
The only anti-histimine pill that it is legal for pilots to use is Clarityn, because it doesn't make you drowsy - and there are a lot of things that you can't take when you're a pilot (I fly sailplanes, which is how I know lol)
