Best medicine for my allergies?

I think I am allergic to pollen and dust.....The roof of my mouth gets ichy and my throght, my eyes ich, my nose gets ichy also, i sneeze alot, ...so whats the best medicine for this...(p.s. This happens when I am dusting my house or if I am cleaning my room it also happens when someone pulls weeds near my house or sometimes when someone cuts grass but not all the time)

cover your mouth and nose when you clean and dust (i'm allergic to dust too), tie something around your head so thet they are covered and benadryll works really well for me.

Zyrtec is the best if you have insurance. Get the doctor to prescribe it for you. If you don't have insurance it is expensive.
benadryl
Try Claritin D or Allegra. You'll have to get Allegra from your doctor. I think Claritin D is still over the counter. They have both helped me.
You need to go see an allergist and get tested for alleriges. The doc will give you a prescription for allegy meds and probably start you on allergy shots.
I've tried claritin, zyrtec, and Allegra.
Allegra worked the best however, after 4 or 5 days, It caused me to have a lot of lower back pain. So now I'm not taking anything.
The Allegra worked so well that I'd say it is worth a try for you. Hopefully, you won't have the same side effect as me.
Good luck
antihistamine together with montelukast sodium before you expose yourself to allergens or the dust and pollen or anything that causes your allergy
