TOD: Flonase works great for me. Don't take it with Claritin-D! That would be overdosing on decongestant. Claritin never did anything for me; I use 24-hour Allegra for the antihistamine and Flonase for the decongestant. It works well, doesn't make me drowsy, and doesn't mess up my voice. (Zyrtec worked well but dried me out too much for singing.) Everyone responds differently to these medications though.
