Effective for lung congestion
63 people found this helpful
I absolutely love this! Although I like Costco's version, you need to take multiple pills to match this one. It's convenient and truly helps me breathe. All cold medications seem ineffective once it reaches your lungs; no amount of Tylenol or Theraflu will clear it out like Mucinex does. I've spoken to others who claim it doesn't work, which is false; you're likely taking the wrong strength (600mg vs 1200mg). Mucinex clears my lungs better than anything else.

I no longer waste my money on other cold products. Mucinex works splendidly for me. I ensure I purchase the product matching my symptoms, such as a runny versus a congested nose. It works great for my family. While it’s slightly pricier, it is well worth it. They even offer cough drops now! I believe everyone has a product that works best for them, and Mucinex has been fabulous for us. So regarding pricing, it balances out since I no longer need to buy other cold and flu products.

Airway clearance success
5 people found this helpful
I adore this product! I use it daily as I have asthma, COPD, and rely on home oxygen therapy. It keeps my airways clear, makes my cough more productive, and helps clear mucus from my lungs. I highly recommend it to others suffering from chest congestion due to any health condition or colds, sinus issues, or viruses causing congestion.

Effective for flu
4 people found this helpful
This is the only medication that truly helps with a chest cold or flu. It contains 1200mg of Guaifenesin, which effectively thins secretions during a bad chest cold or flu, while syrups usually only provide 200mg, along with less effective ingredients.

Shortens cold duration
3 people found this helpful
If you get a cold, get this! It's my go-to whenever I or a family member starts to sneeze and feel a cold coming on. It cuts colds from over 10 days down to 3 or 4, sometimes preventing the cold altogether if you catch it early. Everyone should have this on hand; they are rather large pills, so be prepared for that.
