@palka9898 Hello! First let me say that I feel your pain with this relentless mucous problem!
I use a Trelegy oral inhaler once a day in the morning, Fluticasone Propionate - 2 sprays per nostril at bedtime, and 12 hour mucinex at bedtime. Sometimes I also take a Sudafed PE tablet at night &/or morning as well. With the autumn weather/allergies I am also taking a 24-hour Zyrtec or Claritin. I find the generics of all the OTC meds work for me. In addition, I use an albuterol inhaler as needed and I find the throat spray called Barlean's Immune Throat Spray (Amazon) invaluable to clearing mucous throughout the day! Seems like a lot but it's not difficult to do & if I stay on top of it, the mucous stays at bay & I don't cough or clear my throat so much. I don't take Xhance anymore but it DID get me over the hump in getting this all under control.

All the best in getting your mucous problem figured out!

Best, Carol
