That's a great product. It just made me feel drowsy the next day.

[This review was collected as part of a promotion.] Yes they are very helpful ………. this product helps with what it says it does, but it makes me feel drowsy the next day. I didn't have a fever made me sleep with comfort. I wasn't congested and they absorbed pretty quick.

Gets the job done💯

[This review was collected as part of a promotion.] I've had a terrible cold for a few days now, coughing and phlegm after taking this I started to immediately feel better within the hour, you take 2 tablets every 12 hours as needed & it really helps!!

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!

Good cold tabs

[This review was collected as part of a promotion.] I love the Mucinex 12 hour cold and fever multisymptom cold tabs. It was so good it relieved fever, headache, and body pain. It knocked out my coughing chest, congestion it thin out my mucus and let me cough it out so I really love the product. I would really buy this again. I just really like Mucinex products. It didn't have any smell. The tablets was 16 tablets. They are extended release so I feel like the quality in the consistency of the tabs was just great

Multiple cold symptoms at the same time.

[This review was collected as part of a promotion.] I liked that this medication helped relieve multiple cold symptoms at the same time. It provided relief from congestion, cough, and body aches, at the 12 hour. Formula was very convenient. A great option to keep on hand during cold and flu season.

Product for cough

[This review was collected as part of a promotion.] It helped me a lot with the severe cough I had and the congestion in my chest, the best thing is its duration of 12 hours since I don't have to take the pill every now and then, it hasn't caused me any allergies, no side effects, it's easy to take, it doesn't leave a bad taste, I totally recommend it's a very effective product

Worked well!

[This review was collected as part of a promotion.] This worked really well for my cough and headache. I didn't have any flu symptoms but it worked well in relieving the cough and headache I got from coughing. The pills were easy to take and seemed to last as long as it says on most of the days I took them! All around I would recommend and would reach for it at the store when needed!

It must have for your medicine cabinet

[This review was collected as part of a promotion.] This were great I hope relieve my fever my headache from being so congested, and the bodyaches that I had. It helped break up the mucus in my chest so that I was able to cough the thin loose mucus up. Overall, I'm completely happy with this product. It came just in time as I was feeling under the weather. I definitely must have for your medicine cabinet. The instructions were very clear on how many tablets to take and how to take the medication.

Definitely does its job!

[This review was collected as part of a promotion.] This 12 hour Mucinex is great! It's easy to open and doesn't have a terrible taste. The pills are also a decent size and aren't hard to swallow. I love how they are extended release and last the full 12 hours.
