Clears congestion and keeps you breathing easier for 12 hours!

[This review was collected as part of a promotion.] Mucinex 12 hour worked really well for me when I had a bad cough and congestion. I liked that I only had to take it twice a day and it helps loosen up my muscus so I could actually clear my chest and breathe more comfortably. It didn't feel like I was constantly taking medicine throughout the day which was a plus one. Overall, it was effective, convenient and definitely something i'd use again when I feel congested.

Easy open, helped with a cold

[This review was collected as part of a promotion.] These are extended release tablets so you can't crush or chew them. They had a bit of a fruity flavor going down but are easy to swallow with a bit of water. I've been fighting a cold and these really let me get a good night's sleep as the coughing subsided a bit. Note that there is a painkiller in the pills so be careful what else you take with them. The pills were easy enough to remove from the package.

Worked very well

[This review was collected as part of a promotion.] I have been really happy with the Mucinex 12hr Cold & Fever Muti-Symptom medication. It is very convenient to have one medication that can help with several cold symptoms at once. Love that the medication is dosed every 12 hrs, this makes being compliant with medication so much easier than having to take it frequently. It really helped me with my last cold, I will keep it handy going into this next cold season.

Manages my symptoms well

[This review was collected as part of a promotion.] There aren't many medicine brands I trust more than Mucinex. I love the extended release layer to this tablet. It helps to get me through 12 hours with my symptoms managed, whether that's mucus, congestion, cough, body aches, headache, or fever. This allows me to get through my day and helps treat my cold.

Effective cold symptom relief

[This review was collected as part of a promotion.] I love Mucinex. It is so effective in tackling a multitude of cold symptoms. This came at the perfect time because I was just feeling like I was coming down with something and man it knocked out my body ache and headache. It worked quickly to break up the congestion in my chest helping my chest feel clear. The pills are big but they don't stick and go down smoothly!

Large pills, large impact!!!

[This review was collected as part of a promotion.] When I am not feeling my best and I'm am stuffy and congested, I reach for this trusted brand!!! My family hasbeen using the Mucinex Brand for years!! I am glad for the new formula!! 12 hours cold and fever relief!! The pills are rather large but they help a lot when you are stuff and congested so hurry and swallow them up. It doesn't take long for the Mucinex to kick in and it doesn't make me feel drowsy!!

Great cold and flu relief!

[This review was collected as part of a promotion.] This Mucinex 12HR Cold & Fever Multi-Symptom medicine is a great option when several cold symptoms hit at once. It helps with fever, headache and body aches while also helping suppress cough and loosen chest congestion. The bi-layer tablet is rather unique, with one layer providing immediate relief and the other layer slowly releasing over 12 hours. I really like the 12-hour extended-release formula because it's convenient and means I don't have to keep taking medicine throughout the day. Overall, a convenient and effective multi-symptom cold medicine to keep on hand.
