Good but not 12 hours good

[This review was collected as part of a promotion.] I was sick for about a week and started taking this on day 2. it helped with my headache, my nightly coughs and the phlegm but it did not last for 12 hours. After about 7 hours I started feeling the symptoms again. The packaging wasn't the easiest to open while sick but I got the hang of it. *FYI* don't bend the little corner tab when opening or you will not be able to peal the paper back. I had to learn from that mistake. Overall it does help you get through the sickness just not as long as it states

Reliable relief that lasts all day

[This review was collected as part of a promotion.] Mucinex 12 HR cold&fever tablets are really helpful when I am dealing with a bad cold. It helps with several symptoms at once, especially congestion, cough, fever and body aches. I also love that it last 12 hours, so I don't have to keep taking medicine throughout the day

The best new cold and flu meds!

[This review was collected as part of a promotion.] My kiddos went back to school and of course immediately brought home a summer cold which then they gave to me. This Mucinex was a true lifesaver and brought me back to life. I felt immensely better and functioned well throughout the 12 hour day. The pills were easy to swallow and effective. I've always been a Mucinex fan so it's no surprise their cold and fever meds are so great. Highly recommend!

Can't go wrong with mucinex

[This review was collected as part of a promotion.] This mucinex has been very helpful when I was dealing with a bad cold a few days ago. I like that it targets several symptoms at once instead of having to take multiple different medications. It helped me with my congestion and loosening mucus while also providing relief for my cough. I can honestly say this lasted 12+ hours and I only had to take once a day. Definitely will keep this on hand for the upcoming cold and flu season.

Easy all in one pill!

[This review was collected as part of a promotion.] Recently started battling a cough and cold symptoms- this worked like a charm! It's one pill, has naproxen built in making it one less thing to take. Long lasting compared to most 12hr meds. No terrible pill taste or after taste, huge plus! Easy go to!

A multi-symptom pill that does it all.

[This review was collected as part of a promotion.] When cold and flu season hits, you need a solution that does it all. The Mucinex 12HT cold & fever multi-symptoms has been a game changer for me during recent sick days, effectively easing my cough, fever, headache, and body aches. I appreciate that it doesn't leave an aftertaste, features quality ingredients, and offers great value. Keep a pack nearby and stay prepared for the upcoming flu season.

Great cold/flu med, be mindful if you have a sensitive stomach/sensitive to NSAIDs.

[This review was collected as part of a promotion.] Ive been feeling a little rundown the last few days….had a feeling I was getting sick…. So when I woke up feeling hot, found i had a 101 fever, I figured it was a good day to try out the new Mucinex. I have used Mucinex for years, it's my go to choice for cold/flu meds. This new formula though has Naproxen in it which I hadnt used before, so was curious to see how it would work…. My fever broke within 20 minutes or so of taking the medicine, and shortly thereafter I noticed that the thick phlegm I had upon waking was greatly improved. I felt so much better after just the single dose…. Mucinex is just so much better than the other cold/flu products on the market. The only downside is I did notice I was a little nauseous and I think it was likely the Naproxen that Im not used to taking. All in all though, I'll take it again as I felt MUCH worse before I took it even with the slight nausea.

The size pill isn't large.

[This review was collected as part of a promotion.] After contracting a cold I got this product in and got to try it. It didn't make me sleeping which is a good thing due to a work day. The product worked because I had a low grade fever and it knocked the fever from myself in a matter of an hour. I feel much better.

Eh

[This review was collected as part of a promotion.] It was okay. When I got it. It was crazy because I actually got sick from my kids so lol but it didn't really help any of my symptoms, like at all. I ended up only using it for 3 days till I went to something else but just because it didnt work for me doesnt mean it wont work for someone else!
