this product was adamantly recommenced by my respiratory doctor. I tried it for 5 days and I found it caused a lot of side effects. the burning and swelling in my nasal passages and sinuses was awful. headaches also developed. the side effects kept me awake andmade me absolutely miserable. returned to my regular saline nasal spray and was able to get relief after a few days. a terrible product for people who are already suffering with sinus problems.
