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.

That's a great product. It just made me feel drowsy the next day.

[This review was collected as part of a promotion.] Yes they are very helpful ………. this product helps with what it says it does, but it makes me feel drowsy the next day. I didn't have a fever made me sleep with comfort. I wasn't congested and they absorbed pretty quick.

12 hour cold and fever

[This review was collected as part of a promotion.] Mucinex 12 hour cold and fever usually works great for me! This one has a medication in it for cough suppressant which helps me when i have a bad cough with a cold or flu. No terrible side effects either!

relieves your symptoms quickly

[This review was collected as part of a promotion.] When I received this I coincidentally was going through a cold and coughing. I took the two pills immediately and within hours my coughing stopped until it was time to take it again. It lasted about 12is hours which is great. I am exhibiting no symptoms. Naproxen Sodium is a great pain reliever. Packaging for this is very convenient. You just peel the back and pop it open. And it stores perfectly in my cabinet.

Best Medicine I've tried

[This review was collected as part of a promotion.] I tried out this new Mucinex Medication and it worked wonders for me! I had been very sick and tried quite a few other things and this was the only thing that helped me! It made me feel better not long at all after taking it. It took away my fever and body aches within the hour! Definitely recommend for anyone feeling sick or that has mucus!

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. 💊✨

Extended release up to 12 hours of relief

[This review was collected as part of a promotion.] Absolutely love that this medication does not expire for over two years. Part of the pill is immediate release and the bottom layer is the extended release so that gives you a total of 12 hours of relief. I like how it helps with pain, fever and cough all in one so that you're not having to focus on taking several different medications.

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!

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
