  • Absolutely Amazing
Size: 40 Count (Pack of 1)
I am an old iron lung survivor that has lived many years outside that metal pita pocket, thankfully. However, recently, four years ago, symptoms returned and it was discovered that I have fairly non-functional diagphragms that appeared to be getting weaker. Well, having two health insurances, with Cigna as the primary, I was prescribed for trial a device called The Vest made by Hill-Rom. A truely amazing device that pummeled your chest with pneumatic pulses through a vest system and that loosened the phlegm in your chest and increased the quality of air exchange. After a 3 month trial I called Cigna and they said to go ahead and get it and this information was passed on to Hill Rom. After being billed for it, Cigna changed their minds and left the cost in my hands. Needless to say I could not afford a device that costs, well, lots. So, Hill Rom was kind enough to take it back and I was left with the original problem of struggling to breath. Thank you Cigna (who has nothing in writing to substantiate my claim - strange how things get miscommunicated always to the insurance companies benefit) - now out of my life forever and I hope others take note. Get everything in writing from Cigna, and others. A few months later someone mentioned Musinex and I brought this up with my doctor. He thought it was worth a trial. It was non-prescription and quite expensive, but, thought I would try it anyway. I have not had a better reaction to a medication. I can do things I have not done in two years. I am breathing better and even if not as good as the 20+K Vest, it is am amazing substitute that I do not intend to do without. I do caution anyone that needs to take this over an extended period to check drug interactions with other meds with your doctor. Just a safe practice. ... show more

These provided much-needed relief and were convenient to take at night. They were a great value and arrived quickly, saving me a trip to the pharmacy. I appreciate the convenience and effectiveness of these gels.
