Go to for cold and fever

[This review was collected as part of a promotion.] Mucinex is my go to for cold and fever. Works so fast and keeps you feeling better for a long time. I love how it has a mix of different ingredients that work on all different aspects of sickness simultaneously. This version specifically lasts a long time so you only have to take a dose every 12 hours.

It works!

[This review was collected as part of a promotion.] I feel like every season my family catches a cold or the flu, and I'm constantly searching for a medicine that actually works! Mucinex 12 hr cold and fever multi symptom is that medicine for us. It comes in easy to swallow pills, it's also easy to toss a small square pack into my purse for easy on the go or travel. It says it works for 12hrs and I'm happy to report it does! However, I did notice it took nearly an hour to take affect which is why I left off a star.

Quick, effective relief

[This review was collected as part of a promotion.] Mucinex is a trusted product in our house, and the 12-hour cold and fever multi-symptom is no exception. It's both reliable and effective, which is huge when you feel like your head feels like an almost over-inflated balloon. The pills are easy to swallow, and the combination of a slow-release side and a fast-release side mean you're going to be feeling relief in no time. These dry up every bit of mucus so you can breathe, and leave you feeling like you can face the world again.

They work fast!

[This review was collected as part of a promotion.] The downside is they are rather large pills. They made me a little drowsy so I advise taking them right before bed. But they work fast! I started to feel my throat getting scratchy and by morning I barely noticed any discomfort or irritation.

Works just like it's advertised

[This review was collected as part of a promotion.] I been using Mucinex 12HR Cold & Fever Multi-Symptom to help me get through some rough cold and flu symptoms. I like that it's designed to provide 12-hour relief and targets multiple symptoms at once, including congestion, cough, fever, sore throat, and body aches. It's convenient to take when I'm feeling under the weather and want something that can help me get through the day without constantly taking different medications. Overall, it's been a convenient option to keep on hand during cold and flu season.

The best cold medicine

[This review was collected as part of a promotion.] This is all that works for my husband and i. It works quickly and lasts long so we're not just taking medicine all day. The pills are easy to swallow and don't leave that film taste in our mouth. Much needed as the seasons change!

A must for family's

[This review was collected as part of a promotion.] I have used Mucinex for several years now. I love the convenience of just taking a pill you miss out on the nasty taste of liquids. This gave me quick relief for those seasonal sicknesses, especially with two small kids. Our house stay sick. This will be amazing in the winter months. This relieved my headache, my fever, my congestion, and my cough!!

Eh

[This review was collected as part of a promotion.] It was okay. When I got it. It was crazy because I actually got sick from my kids so lol but it didn't really help any of my symptoms, like at all. I ended up only using it for 3 days till I went to something else but just because it didnt work for me doesnt mean it wont work for someone else!
