Fast working pills

[This review was collected as part of a promotion.] Mucinex 12 hours cold & fever multi symptom works great. Now, when it's a flue season, and school started, lots of people get sick. It's really easy to catch cold. After taking just one dose, I felt imitated relief. I do appreciate Bi-Layer concept, and I can see the result for sure. I will keep these pills in our medicine.

Great to have during cold season

[This review was collected as part of a promotion.] I like that this helps with multiple cold symptoms in one product, specially congestion, cough, headache and body aches. The 12 hour formula is also really convenient when you're not feeling your best

12 hour relief

[This review was collected as part of a promotion.] I was not feeling well and was nursing a 101 degree fever with congestion. Took this medicine and it helped me get some rest. Really appreciated the 12 hour relief. It's just nice to know that I don't have to take a dose every 4-6 hours!

Superstar

[This review was collected as part of a promotion.] These product worked wonders for me. I been under the weather and don't see doctor often. The Mucinex 12 hour worked well. Easy to go down, no after taste, works the full 12 hours. Helped suppress my cough and loosen that forever mucus. My son was sick as well and used these. Definitely recommend

Great medicine when sick!

[This review was collected as part of a promotion.] My go to medicine when I'm feeling sick or have a fever or cold. It works fast and lasts as long as 12 hours in my system. It's not drowsy so I can take it during the day and continue doing my usual work.

Fast/long acting

[This review was collected as part of a promotion.] Provides relief for cold/fever symptoms such as congestion, fever, headache. I found it to be fast acting and gave relief for the full 12 hours. The pills are a little large and not coated, however the medicine is effective so it's an OK trade off.

Great for multiple symptoms

[This review was collected as part of a promotion.] Mucinex always comes through for me and this was no exception! The Naproxen sodium kept my fever down and soothed my aches. My cough stayed under control thanks to the Dextromethorphan. And, the Guaifenesen thinned out my congestion so I could get it out of my chest

Convenient 12 hour relief for multiple cold symptoms in one product Convenient 12 hour relief for multiple cold symptoms in one product

[This review was collected as part of a promotion.] I really liked having this on hand when dealing with multiple cold symptoms at once. The 12 hour formula is convenient because I don't have to think about taking something as often, and I like that one product is made to target cough, chest, congestion, fever, headache, and bodyaches. The tablets were easy for me to take, and overall it made getting through a rough cold feel a lot more manageable. I'll definitely keep this in my medicine cabinet for cold flu season

Mucinex is my go to when sick

[This review was collected as part of a promotion.] I always go towards Mucinex every time I'm sick so when I got this, I was like oh it's perfect because I buy it anyways honestly, I think it's honestly one of the best things in the market for a cold and flu symptoms and it's decently priced I haven't got sick yet to use it, but I'm aware of Mucinex and it's brand so I know it's gonna work well.
