Question: is dymista good for sinus infection?
Answer: They probably do help, to a small extent, with acute sinus infections, but work best preventively. Nasal Antihistamine sprays, such as Astelin (azelastine), Astepro, and Patanase can help with allergies, but don't help with sinus infections per se. Dymista is a combination of a steroid and an antihistamine.
