Great for the flu season

Fast relief for cold symptoms

[This review was collected as part of a promotion.] Mucinex 12 Hr Cold and Fever Multi-Symptom tablets worked great for relieving congestion, body aches, fever, and cough. The medicine provided long-lasting relief without needing frequent doses and dissolving very easily . Easy to swallow and effective during both day and night. The 16-count pack is convenient to keep on hand during cold season.

Very Effective!

[This review was collected as part of a promotion.] I recently got sick and when I used this product I thought it was very effective! I did not have any side effects and the feeling was consistent all day. The ingredients were good and it did not have a smell to it!

Cough it up, get it out!

[This review was collected as part of a promotion.] I have been fighting a chest congestion every morning and this mucinex extended release has really helped. My coughs have been productive on getting stuff to break up and get it out of my chest. It keeps thw headache at bay that comes soth the cough. It has been a lifesaver

Symptom relieving cold medicine

[This review was collected as part of a promotion.] Mucinex 12HR Cold & Fever Multi-Symptom medicine is like a game changer! When I'm sick, what I find the most hard is waiting for my next medicine because most of them looses their symptom relieving functions after a few hours. This one, having a bi-layer system composed of immediate release and extended release, seems to have solve this problem. I really like the thoughtfullness behind it. The only thing I did not like is that two medicines are in one blisters, I'd prefer if all had their own blisters.

Good for mucus

[This review was collected as part of a promotion.] My favorite thing about this brand is I know it's gonna help me out with mucus buildup which i feel is the worst part of being sick and having a cold. This also worked on reducing the fever. It's summer time no one wants a cold in summer but with this product it helped me get through the days until i felt better completely! It's pills that have an extended release period so i don't really taste them.

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. 💊✨

Really good

[This review was collected as part of a promotion.] I want to start by saying that suddenly getting a cold the day before I received this was weird juju lol I took this sample for a "juat in case" moment but here it was. It didn't cause palpitations, works well for 10-12hrs. Did not cause drowsiness and I like that it has fast release and a longer lasting one. Also, no weird dreams.

Easy to swallow

[This review was collected as part of a promotion.] I recevied this product for free from Influenster and Mucinex in exchange for my honest review. Mucinex works amazing for me when I am sick with a cold or flu. I like that this all in one pill offers naproxen instead of acetaminophen because sometimes acetaminophen isn't strong enough for my aches and pains. They are easy to swallow even though they look big. I like that this lasts 12 hours. I recommend Mucinex especially if you're really congested or coughing bad.
