It was good

[This review was collected as part of a promotion.] Muxinex's new 12 HR Cold & Fever Multi-Symptom medicine is conveniently packaged with peelable instructions on the back. The strength of the medicine is extended release tablets that include naproxen sodium as the NSAID. They have no smell.

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.

Long lasting relief

[This review was collected as part of a promotion.] This Mucinex 12HR Cold & Fever Multi-Symptom is an excellent product to have on hand when the symptoms match the need. Packaging is great and secure with 8 full standard doses of 2 tablets each (16 tablets total) with a simple tear packaged dose from slide set and peel off back layer. The effectiveness has been great for me at easing my heavy cold and fever symptoms by helping reduce my fever, ease my cough, and loosen congested mucous and overall discomforts. The 12 hour formula is perfect for not needing frequent doses and truly feeling that relief for that amount of time. I have not experienced any side effects, only desired effects and the tablet size is great and simple to swallow and seems to dissolve in my system quickly to get relief soon.

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.

It's great to have in home

[This review was collected as part of a promotion.] I recently tried Mucinex 12 Hr Cold & Fever Multi-Symptom medicine and found it really helpful when dealing with congestion, body aches, and fever symptoms all at once. The packaging is compact and easy to store in a medicine cabinet or travel bag, and the caplets are a manageable size that weren't too difficult to swallow. The dosage instructions were straightforward and easy to follow, which made it convenient to take during the day without confusion. The product has a mild medicinal smell, but nothing too overpowering or unpleasant compared to other cold medicines I've tried. In terms of duration, I liked that the relief lasted for several hours and helped control my symptoms without needing constant re-dosing. I personally didn't experience major side effects, although I did notice slight drowsiness after taking it, so I would recommend being mindful of that depending on the time of day. Overall, it worked effectively for multi-symptom relief and made cold recovery feel much more manageable.

Very good multi-symptom!!

[This review was collected as part of a promotion.] I must say that this brand is the one that I buyed for my kids, and this multi-symptom is very good for me, because when the weather changes I get cough, fever and multi symptoms, I have to take 2 tablets for every 12 hrs, I don't have any side effects, because I'm not allergic to the ingredients,the effectiveness is great, the texture is good, I recommend it. Thanks to influenster and Mucinex brand for this opportunity to try this great 12 hr cold and fever multi symptom.
