A total lifesaver when you're dealing with all the symptoms at once!

[This review was collected as part of a promotion.] What I love about this most is the 12-hour relief. You can actually get through a full work day or a solid night's sleep without waking up congested or achy the second a standard dose wears off. It really knocked out my fever and loosened up my chest congestion quickly. The tablets are on the larger side (typical for Mucinex), but absolutely worth the extended relief. Definitely keeping this stocked in my medicine cabinet!

"Marvelous Mucinex!"

[This review was collected as part of a promotion.] This "Mucinex 12-Hour Cold & Fever Multi-Symptom" Medicine is always fantastic to have on hand! 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. Thank you to Influenster and Mucinex!

Would I buy it again? Yes, especially during cold and flu season when I need reliable symptom relief.

[This review was collected as part of a promotion.] I recently tried Mucinex 12-Hour Cold & Fever Multi-Symptom when I was dealing with a nasty cold, congestion, and body aches. What I liked most was that it targets multiple symptoms in one product, helping with fever, headaches, body pain, cough, chest congestion, and mucus. The extended 12-hour relief was convenient since I didn't have to keep taking medication throughout the day. I noticed my congestion loosened up and my body aches became much more manageable. The tablets are a little large, which may be difficult for some people to swallow, but that's my only real complaint. Overall, this is a solid option for cold and flu symptoms if you're looking for long-lasting relief and fewer doses throughout the day. It helped me get through the day and rest more comfortably at night. Pros: ✔️ Long-lasting 12-hour relief ✔️ Helps with multiple symptoms at once ✔️ Effective for congestion and body aches ✔️ Convenient dosing Cons: ❌ Large tablets may be difficult to swallow

Great for fever reducing

[This review was collected as part of a promotion.] This is a great product!! I was on vacation recently and threw a few of these in my bag. I woke up one night fighting a fever and took this right away. Within a day, I was completely back to normal!

Mucinex to the rescue!

[This review was collected as part of a promotion.] First off the packaging is super cute, I love the rainbow hologram. Second I got a summer cold, and didn't feel well at all. These instantly made a difference very quickly, and helped me get a good nights sleep. They don't have a funky bad taste at all, and they last for a really long time. Definitely a must have if you're not feeling good!

Good cold medicine

[This review was collected as part of a promotion.] Having a cold and warm weather really stinks! I took this and definitely was much improved the next day. No cold medicine is perfect and doesn't get rid of anything instant instantaneously, but this seems to be a good one that I would definitely try again

Works great!

[This review was collected as part of a promotion.] They aren't too big so it makes them easy to swallow and leaves no weird taste in your mouth afterwards. Took this at night and woke up feeling 10x better! Definitely worth getting to help get over a cold/ fever fast.

Recommend to everyone

[This review was collected as part of a promotion.] Overall the 12hr cold and fever Mucinex is a game changer and came in during a perfect time while me and my family where sick. We got so much relief from this medicine and there's no taste since it's a pill.
