Effective

[This review was collected as part of a promotion.] I really liked mucinex because it combines several ingredients to help with different cold symptoms in a single tablet they are easy to take they have no flavor a very good option to have at home in this cold season.

Provides relief from congestion and fever

[This review was collected as part of a promotion.] Very interesting packaging very different from other mucinex products. I rated this a 3 because I felt it didn't last the full 12 hours. I will say it provided some relief for maybe half that time so I'll take it. Helped most with helping get congestion out. Not too much on cough. Overall a decent product.

Makes me relief from cold and flu

[This review was collected as part of a promotion.] This medicine gives me relief from fever, headaches, and body pain when I'm feeling under the weather. I can count on it when I have cold and flue like symptoms and it helps me feel comfortable. It's convenient to have this medicine handy during cold and flu season. I would recommend to anyone who deal with cold and flu symptoms.

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.

Very good

[This review was collected as part of a promotion.] I love that the ingredients are clearly listed on the packaging and their benefits to calm the cold symptoms. I did not notice any smell or aftertaste. I like that the dosage is simple and convenient. The onset is always fairly quick . I was so congested and I felt a total refuel after a few minutes of taking it.

Great

[This review was collected as part of a promotion.] 12 hour multi symptom is so perfect to have on hand. I have a little one in kindergarten and I am always fighting off a sniffle or cold. Easy to take and make it able to make it through the day to feel better.

Easy Relief

[This review was collected as part of a promotion.] If you have a common cold I would say this would be something that could be purchased to provide relief quickly. It is worth mentioning the pills are a bit on the larger side, but they are easy to take.

My doctor boyfriend and I are always getting sick, and Mucinex had him feeling better within days.

[This review was collected as part of a promotion.] My boyfriend is a doctor and seems to always be getting sick and of course I end up getting sick too. He tried Mucinex and was already feeling noticeably better over the next few days. I like that I helped with multiple symptoms at once, especially the cough, congestion, and bodyaches. The 12 hour relief was also really convenient when we were feeling awful. Definitely something I'd keep around during cold and flu season.

I like it to be 12 hours

[This review was collected as part of a promotion.] I like it to be 12 hours, because it is very practical and I do not have to be aware of taking it so often. For me it has been a good choice for those days when you feel a cold and need some relief.
