Kicked our cold quickly!

[This review was collected as part of a promotion.] We ended up with a yearly summer cold from traveling so I was excited to try this product. We are pretty big fans of this brand in our house but hadn't tried this until we got selected to review it. It helped knock out our cold faster than other ones we've tried in the past. The packaging was nice and eye catching if I was shopping for it again in the future. Great product!

Twelve hours of serious cold relief!

[This review was collected as part of a promotion.] Eye catching packaging, really highlights the active ingredients. Twelve hours is what you come to expect from Mucinex, this is often the only medicine I take for a really bad cough! The texture is a smooth capsule shaped pill, doesn't seem chalky. This does thin your mucus, so just be prepared for that to come out somehow! Any serious side effects are listed and should be seen by a doctor.

All medication in one pill

[This review was collected as part of a promotion.] This cold medication includes everything you need in one pill to help you better better. In one pill, it has medication such as naproxen 110mg for pain or fever, dextromethorphan hbr 30mg for cough suppressant and gauifenesin 600mg which is an expectorant. I would definitely recommend getting it which has everything in one pill. Size of pill is little on larger size

Another Solid Product

[This review was collected as part of a promotion.] I have been using Mucinex products for years and was happy to get the opportunity to try this new one. The packaging is easy to open and access. The tablets are easy to swallow and didn't leave a bad taste in my mouth. The ingredients are very potent and my symptoms eased with the first dose.

Great for many reasons

[This review was collected as part of a promotion.] This Mucinex product is great for many things. It has a quick release for headaches, plus extended release to last for 12 hours. There are very clear instructions on the packaging and fits well with the Mucinex brand.

This medicine is 🫶🏽

[This review was collected as part of a promotion.] You know that feeling when you're dealing with congestion, aches, fever and just overall blah energy? Yeah... this was the product I reached for. What I appreciated most was not having to juggle multiple medicines for different symptoms. Congestion? More manageable. Body aches? Calmed down. Getting through the day? Much easier. And can we talk about the 12-hr coverage? Because nobody has time to be constantly the clock for their next dose. Being sick is never fun, but having something reliable in the medicine cabinet makes a huge difference. 💊✨

Very effective

[This review was collected as part of a promotion.] My husband loves this brand! Every time he gets sick he goes for mucinex. He always feels better faster than with other brands so it's effective for him. I like taking medication but not as much I'll always pick natural but when it comes to strong cold and fever we go for mucinex

Great product

[This review was collected as part of a promotion.] Mucinex is one of my go to meds when I have a lot of congestion and mucus. They are very easy to swallow and doesn't leave a nasty taste in your mouth. It take a couple days taking these and I already start feeling better. It doesn't smell so that's a plus.

Effective all in one cold and fever relief.

[This review was collected as part of a promotion.] The mucinex 12 hr cold and fever multi symptom helps with cold, persistent cough, chest congestion, body aches and fever. I liked that it combines a cough suppressant, expectorant, and fever/pain reliever in one product so i didn't have to take multiple medications. The tablets were easy to take and appreciate the connivence of 12 hour dosing.
