I was prescribed this when I was diagnosed with bronchitis in October 2013, but have discontinued its use. Since that time I have been re-diagnosed with an upper respiratory infection and sinusitis. I have been on 2 courses of antibiotics, but I still continue to have severe nasal decongestion/ having to blow my nose ALL DAY, and a productive cough. Would starting the Bromfed DM again help my nasal decongestion?
