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.

Works fast!

[This review was collected as part of a promotion.] This came in handy at the perfect time. I'm not one to get sick all but when I do I need something that gets me back to normal fast! As a mom, I can't be down for the count! This Mucinex did the trick and within about 24 hours I was back to normal!

This medicine help me a lot

[This review was collected as part of a promotion.] Mucinex 12 HR Cold & Fever Multi- Symptom provided noticeable relief headaches. The extended 12- hours formula was convenient since I didn't need to take it as often throughout the day. It's helped me feel more comfortable and functional while recovering from a cold. The tablets are a bit large, but overall it's an effective option for managing multiple symptoms with one medication

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.

12hour

[This review was collected as part of a promotion.] Excellent Cold and Flu Relief! I was really impressed with Mucinex 12HR Cold & Fever Multi-Symptom. It helped relieve my fever, headache, body aches, and cough quickly, and the effects lasted for many hours. I also noticed that it helped loosen mucus and made breathing much more comfortable. The extended-release formula is very convenient since I didn't have to take it frequently. Overall, this product provided effective relief and helped me feel much better while recovering from my cold. Highly recommended!

Works great

[This review was collected as part of a promotion.] Received this free for review. I got this at a good time since there is something going around at work. It worked great, fast acting. It does not make you drowsy. I definitely recommend to anyone who doesn't feel good.

A very good product

[This review was collected as part of a promotion.] I received this product from @Influenster for free for my honest opinion of the product. I used it for several days. I took 2 pills at a time. It helped with my congestion in my chest. It also helped with most of my symptoms. It never made me drowsy. I was alert after taking the 2 pills.

Love this for cold

[This review was collected as part of a promotion.] The best thing for a cold! I love that it's for 12 hours instead of the usual 6-8, so I can sleep and feel great all night without waking up and coughing. It does not expire fast but it does absorb fast, within 30 minutes I felt so much better.
