Actually long lasting cold support!

[This review was collected as part of a promotion.] This came at the perfect time for us, dealing with a nasty cold our daughter passed on from daycare. My husband especially had a horrible cough and it didn't seem like anything was helping. He found so much relief with this! He was able to actually get some much needed sleep without being woken up by his coughing. We both really like the extended release formula, because often we find cold medicine helps initially but isn't long lasting. He felt like this stayed consistently helpful for 12 hours! We definitely will keep this stocked in our medicine cabinet for the future. :)

12 hour relief

[This review was collected as part of a promotion.] I was not feeling well and was nursing a 101 degree fever with congestion. Took this medicine and it helped me get some rest. Really appreciated the 12 hour relief. It's just nice to know that I don't have to take a dose every 4-6 hours!

Macinex Helps Fight Those Stubborn Colds!

[This review was collected as part of a promotion.] Mucinex is so great for those stubborn colds. I take this and it truly helps with those miserable days feeling sick. I really enjoy how easy it is to ingest this too. All in all, this is great for those stubborn colds.

Great

[This review was collected as part of a promotion.] This is my first time trying Mucinex 12 hour cold and fever multi symptoms medicine and this works amazingly well. I like the fact that it can last up to 12 hours and keep you well. The pills are small enough and easy to swallow. I also like that it has multiple uses and can help in many ways. This is perfect for the winter coming ahead.

Amazing

[This review was collected as part of a promotion.] This Mucinex 12 hour cold and fever multisymptom relief is a game changer! I love that it is 12 hours as opposed to the typical four hour Mucinex tablets and it works great to help with a bad cold without having to continuously take more medicine

Must have! For flu season

[This review was collected as part of a promotion.] This couldn't of come at a better time. My whole house is sick because this weird weather!! My husband was acting like he was on his death bed but right after he took this he was out and about again feeling better. It helped him so much longer than other brands !! And the pill form always better than liquid takes a little longer to work

Very effective to me

[This review was collected as part of a promotion.] This is so amazing. My mucus got loosened quickly with this. I feel a lot better not long after taking this. The fever and headache are reduced a lot. It is also easy to take. This is very effective. I appreciate it a lot.

An essential when you're sick!

[This review was collected as part of a promotion.] This Mucinex 12hr cold and fever medicine is an essential when you're sick! Not only does it help with your cold symptoms, it also helps with fever and body aches so you don't have to take an extra medicine for that!

Works great

[This review was collected as part of a promotion.] Worked much better than I expected. Was taking a liquid for a couple days and was not really helping. Took the Mucinex last night and then again this morning and I'm already feeling 90% better. Will definitely be using this from now on

[This review was collected as part of a promotion.] Have not gotten sick yet so haven't used this product but when I do I will update. Easy to use instructions love that it's a 12 hr dosage makes it nice for people who hate having to figure out how long it's been with shorter dosages. Helps with fever headache body pain cough chest congestion and thins & loosens mucus,
