Although risky to change sinus meds during a horrible allergy season (in addition to year round allergies), I was tired of taking pseudoephedrine every day for the majority of the year, in addition to my allergy medicine. I found this remedy and liked the ingredients and the fact that I would be off a medicine with so many side effects and long term issues. I am really pleased with the results so far. The sinus formula has still kept me clear, with little or no headaches forming, and have not shown to have any side effects. If it continues to work, I will be a life long customer!
