what type of allergy med? You might be best off just looking into a dr.'s appointment, if you have health insurance. If not, I'd reccommend warm water gargles, warm teas (I think liquorice has antimicrobial properties...)...
oh, and Knot's honey and apple cider vinegar tonic. I think it's somewhere in the 'health' column, but honey does wonders for sore throats, and the apple cider vinegar might help you, being just acid enough to maybe kill some of the irritants.
All in all, the no-fever, no-spots say it's an irritant like sinus drainage. I'd be hesitant to clean your sinus passages as often if the warm saline solution is running down your throat too much.
