Works fast to get a sick sole back to their feet

[This review was collected as part of a promotion.] This came just in time for my older brother that had been battling a severe cold for a week! I gave this to him and within hours he was back on his feet. He literally had been in bed sweating and having to change sheets from it. This was very convenient and effective in a short time!

12 Hour Relief in One Pill

[This review was collected as part of a promotion.] This is the type of product we need. It has Naproxen Sodium(NSAID) instead of Acetaminophen so the fever and pain relief last longer and the dosing can be every 12 hours. There are 16 doses per package, so actually get a lot of product. Mucinex is a great product so anything they make I will try.

Better than I imagine

[This review was collected as part of a promotion.] I recently tried Mucinex 12HR Cold & Fever Multi-Symptom during this cold season, and it was a lifesaver for managing my symptoms. The extended-release formula worked for hours, so I didn't have to keep taking doses throughout the day. It really helped with my cough, chest congestion, body aches, fever, and even loosened up mucus so I could breathe more easily. One of the things I appreciated most was that it didn't make me feel overly drowsy, which meant I could still be productive while recovering. The tablets are a bit on the larger side, but the long-lasting relief made it worth it. Overall, I highly recommend keeping this on hand during cold and flu season!

Better symptom relief!

[This review was collected as part of a promotion.] I am looking forward to using these this winter during cold season. Mucinex has always been my go to for cold medication but now it has Naproxen instead of acetaminophen! The Naproxen will help it relieve pain and headaches symptoms so much better and faster! The tablets are a beautiful pink and white, so they eill be easier to distinguish from other Mucinex products. They are coated and easy to swallow and still offer 12 hour symptom relief!

Convenient 12 HR relief for cough, congestion,fever , and body aches in one product.

[This review was collected as part of a promotion.] I tried Mucinex 12HR cold& fever Multi- Simptomp during a cold , with cough,congestion , body aches and headaches .I like that it combines ingredients for cough , mucus and fever relief in one product , and the 12HR formula was convenient . I helped loosen mucus and made me feel more comfortable while recovering.The tablets are easy to take ,although the size maybe a little large for some people.Overall I would recommend it for multi symptom cold relief .Since these are tablets there isn't really a strong flavor, which I personally prefer over overly sweet cold medicine

Feeling better after the FIRST dose

[This review was collected as part of a promotion.] This could not have came at a better time! I am a nurse and currently dealing with a cold and this medicine made me feel so much better even after the first dose. It didn't make me groggy, or feel like I had no energy which I love. Highly recommend and this will be a regular purchase for me.

Helps kick sickness faster

[This review was collected as part of a promotion.] Honestly, when a bad cold hits, I don't have the energy to keep track of taking medicine every four hours. That's the main reason I grab this specific Mucinex 12HR Cold & Fever—you take it once, and it actually keeps working through the day so you can function. It covers all the basics (fever, body aches, and a bad cough), but it's especially good at clearing out that heavy, stubborn chest congestion. ​If you're building a sickness survival kit, definitely keep a box of this and some decent tissues on hand. It saves you from having to run to the store when you're already feeling like trash.

"Marvelous Mucinex!"

Not only is there the perfect number of extended release tablets in this box, but they are 100% effective. When my family and I are feeling under the weather, it's always good to know that Mucinex is here to help us power through and feel our best, so I would recommend these.

Lo mejor 🍋‍🟩🤧🍵

[This review was collected as part of a promotion.] In general I had a very good experience with this product the onset was quite fast and helped me relieve cough and congestion without making me feel worse. The duration was impressive. Because the relief lasted several hours the texture of the tablet was easy to take as soon as sideettects I did not experience anything remarkable which made the experience a better one
