Get relief now!

[This review was collected as part of a promotion.] The best cold and fever medication that last for 12 hours. Gives you relief and a good feeling. This Multi-symptom medication is non drowsy, you are able to take it anytime. Easy to swollen and the flavor is not bad.

Great for those intsense colds

[This review was collected as part of a promotion.] I get sick pretty easily throughout the year and I love Mucinex because it has always been really quick to work and I love this product because it actually helps my symptoms for 12 hours. It's a multi symptom product that is great for headaches, body pain, fever and it clears up my congestion so quick so I highly recommend.

Starts working fast!

[This review was collected as part of a promotion.] This medicine arrived at the perfect time. I had just gotten my yearly, summer cold. What I usually take never seems to help. However, by the second dose of Mucinex I was feeling better. Bonus, no drugged feelings!

Good medicine but I nèed atronger

[This review was collected as part of a promotion.] Mucinex is good for a cold. This has all the different medicines I normally take when I have a cold However this formula isn't strong enough for the kind of colds I experience.I need more of the dextromethorphan and guaifenesin. For those that have CKD this formula has Naproxen Sodium which can be dangerous for kidneys. I would recommend this for the average person. Those with health problems use with caution. I like the packaging because it states everything in the medicine. Also it is easy to read.

Effective Multi-Symptom Medicine!

[This review was collected as part of a promotion.] Mucinex has such a great reputation for creating effective medicine, and this product is no different! It is great to have on hand, especially as we enter cold and flu season! It provides strong 12 hour cold and fever relief- which directly targets a fever, headache, body pain, cough, and chest congestion! It also helps to loosen and thin mucus. You also only need two pills every 12 hours- it has both an immediate release and extended release layer! I would highly recommend this!

Good to have on hand

[This review was collected as part of a promotion.] Received in the midst of a summer cold so the timing was great. Really great. Kind of big pills if that's an issue, but was helpful for the cold symptoms and cough with drainage! Good to have on hand!

great for cold and flu season

[This review was collected as part of a promotion.] these are great pills to take whether you have a fever, cough or sinus issues that caused a lot of mucus. I found that it easily thinned the mucus so it was more comfortable to breathe and eventually stopped it altogether. I really love that these last for 12 hours so I don't have to keep taking a pill every 4 to 6 hours. The pills were easy to swallow since they weren't too large. Overall, perfect for the upcoming cold and flu season.

Love it

[This review was collected as part of a promotion.] I'm a huge Mucinex fan so I was really excited to try it. It's another great product by Mucinex! This stuff really did help my cold within an hour or two, it was pretty quick. By the second day my fever had gone away and I was getting back to normal. They come out with products that really work and work FAST! They're really easy to swallow and take.
