Fast acting

[This review was collected as part of a promotion.] Came just in time for my summer cold🤧 I was running a fever and just all around not feeling good and took a dose and felt better within a few hours! fever came down and i felt like i could actually get out of bed and walk around without feeling horrible. Doesn't leave a bad taste in your mouth while scrambling for the water bottle very good stuff! Definitely will be keeping this in my night stand for all these colds i catch!

Love the medication.

[This review was collected as part of a promotion.] Mucinex 12 hours cold and fever multi symptom is a good medication to take when you have a cold and fever. The product arrived at just the right time, as I had a fever due to the change in weather and the medication helped me a lot. I recommend it.

Loosens mucus for up to 12 hours

[This review was collected as part of a promotion.] Fever, headache and body pain. Couch plus congestion. Thins and loosens mucus. No taste. Works for 12 hours. No directions listed on package tho. So I have to assume I take one tablet every 12 hours.

Long lasting cold relief

[This review was collected as part of a promotion.] I've been a faithful mucinex user for awhile now. It's the only thing that clears up my congestion. This new product works on multiple symptoms at the same time. Instead of having to take pain relievers, decongestants and cough medicine, Mucinex has combined them all in one. It's long lasting and easy to take in one pill. I can see this being a staple in my home during cold and flu season.

Great for individual individuals who have cold symptoms!

[This review was collected as part of a promotion.] This is a great product for people who are experiencing cold symptoms. It has several different ingredients, including naproxen, a cough, suppressant, and an expectorant. I would recommend this product if you are experiencing fever, headache, body, pain, cough, congestion, and thick mucus. Also enjoy how it is extended release over 12 hours.

Great all-in-one cold relief!

[This review was collected as part of a promotion.] Works really well when you are dealing with multiple cold symptoms at once. It helps reduce fever, body aches and chest congestion. It like that it lasts 12 hours, so I don't have to take medication throughout the day.

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.

Go to telief

[This review was collected as part of a promotion.] This provided instant yet long-lasting relief. We always end up with some summer ick, and this was our go-to for it. Helped with congestion and being able to breathe again. It's definitely a repurchase!

Quick & Extended in One

[This review was collected as part of a promotion.] I really like that this medication provides both fast acting relief and extended 12 hour symptom control in one pill. It helped relieve my cold & fever symptoms quickly and kept me feeling better throughout the day. I was pleased with how well it worked and would definitely recommend it.

Will be my go to medicine when sick.

[This review was collected as part of a promotion.] It helped relieve my congestion, body aches, fever, and cough without needing anything else. Helped me sleep at night comfortably. It's helped in a few hours. They are not hurt to take and did not taste bad. This will be my go to if I feel horrible and need help with my code asap.
