Works wonders

[This review was collected as part of a promotion.] I'm never disappointed with Mucinex. Got this product at the perfect time. My symptoms improved within the first day of taking this. Especially the congestion and cough. I was able to sleep better without waking up coughing. Easy to swallow pills they were not to big.

Convenient and effective 12-hour medication

[This review was collected as part of a promotion.] As soon as school started, I knew that my kids were going to bring home THE GUNK. Sure enough, they did, and I'm snotty, achy, coughing, and miserable. I'm used to using other products, but I've never been entirely satisfied with them, and it's always a pain when you have to cross-check medications in a multi-med product to ensure that it's safe to use with whatever else you've taken. I thought that Mucinex 12 HR Cold & Fever Multi-Symptom was really unique in that it contained not acetaminophen, not ibuprofen, but Naproxen Sodium - a NSAID - that isn't always in your medicine cabinet. Especially as this is a 12-hour dose, you might want to take acetaminophen for breakthrough aching or fever. This allows you to do just that without worry. I will note that this product contains Dextromethorphan (a cough suppressant) and also Guaifenesin (an expectorant), which might sound counterintuitive - how can you use an expectorant if you're suppressing your cough? I personally find these helpful in combination because most of my coughing is eased, and that which isn't eased is far more productive. I found this product to be helpful for my symptoms, and I really liked that I was able to take acetaminophen during that 12-hour time if it was needed. Each pill packet contains two fairly large pills, but they were smooth and easy to swallow with no unpleasant taste. I would absolutely reach for this product in the future during illness.

Definitely works!

[This review was collected as part of a promotion.] Mucinex has always been a good choice for our home. Usually the liquids. Since the kiddos are now older, and no longer kiddos, we upgraded from the liquid to the pill format. They still work absolutely fast and get the job done, sooner than other brands! With the pill form, I get no real taste (I don't let them sit on my tounge though, either) Simple packaging, easy to pop out and use Due to the simple packaging I absolutely recommend STORE HIGH AND OUT OF REACH OF SMALL CHILDREN! Otherwise, amazing product! 👌

The answer for a summer cold!

[This review was collected as part of a promotion.] These Mucinex 12 hour cold & fever were here for me just at the right time. My nephew was playing his first home game of his senior year and I was feeling terrible. I remembered that I had these so I took them the day before the game and I was able to go because these cleared up my congestion and helped get rid of my headache. Love Mucinex. I definitely recommend these to everyone.

Works great

[This review was collected as part of a promotion.] I love this product and buy it every winter. Everybody in my house uses it because it works so great. When you have that cough, but nothing comes up but you know it's down there. This is great to take because it breaks everything up so you're able to cough it up and feel much better.

12 hour relief

[This review was collected as part of a promotion.] This multi symptom mucinex has done me wonders this flu season. I have been fighting a cold for the last few weeks and it has given me relief to be able to go to work and function normally. The extended release gives relief all day long

Trusted brand

[This review was collected as part of a promotion.] These pills are quiet large but they work within an hour. I love Mucinex and I've been using them for years. Not only does this help with my cough but it helps by thinning my mucus and has pain and fever reducer. Mucinex is a great trusted brand

Works fast without making me drowsy

[This review was collected as part of a promotion.] Mucinex is the only product I will use for cough, so I was excited to try this new multi-symptom version. It did not disappoint. It works fast to break down mucus and clear out anything that is causing the cough in addition to bringing relief to fever, muscle aches, and other cold symptoms. It doesn't make me drowsy like other brands do.

Sick day must have

[This review was collected as part of a promotion.] I used this medicine when our household came down with a cold, the mucinex cold medicine helped bring down fevers and alleviate our symptoms (cough and mucus) would repurchase this product in the future!

Game changer

[This review was collected as part of a promotion.] Took a Mucinex 12 hour cold and fever multi symptom tablet and I can stay within a couple hours I saw a difference. I was able to stand on my feet and complete tasks that I normally wouldn't while fighting a cold and fever. Game changer.
