I was about to recommend Mucinex which I was first introduced to while in the hospital with pneumonia for 7 days. I was delighted to see others recommending it to you also. My allergist agreed that whenever my allergies are going extra strong to add Mucinex to my regimen. It has made a significant difference in my life. Before using it when needed, I was hospitalized with pneumonia 3 times. Please speak with your allergist about using it when needed.
