Can I take an otc antihistamine along with bactrim (sulfamethoxazole and trimethoprim) and prednisone? It is not for allergic reaction from bactrim (sulfamethoxazole and trimethoprim), just for pollen allergy

In brief: Yes

However, you may find that the prednisone (assuming you're using it for something else) helps more for the pollen allergy than antihistamine.
If you are receiving treatment for chronic or worsening sinus pressure/infection, then I strongly recommend seeing an Allergist to get help in the future. Recurrent sinus infections will persist unless the allergy is addressed properly. Good luck!
