Didn't notice any help with my sickness

[This review was collected as part of a promotion.] I have been more sick than I have been in a long time. Some kind of virus that had me so congested my head felt like it was going to pop. I took this Mucinex to try and find some relief from my congestion but I did not notice any relief from it. It didn't thin out the mucus I had, I was still so congested I couldn't sleep. I ended up getting other meds that helped me so much better.

I loved it! Convenient, effective, and lasts for 12 hours—it really made a difference when I had multiple symptoms.

[This review was collected as part of a promotion.] I absolutely loved Mucinex 12 HR Cold & Fever Multi-Symptom! It truly exceeded my expectations. It helped me a lot with several symptoms at once, such as congestion, cough, aches, and fever. I especially loved that it lasts for up to 12 hours because it made my day so much easier and I didn't have to worry about taking it several times. For me, it really made a difference when I wasn't feeling well. I would definitely recommend it!

Part of the new sickness line up

[This review was collected as part of a promotion.] Part of the new sickness line up! With back to school, I've already gotten sick with the new germs flying around. This medication helped to get me back up on my feet. It's very effective in comparison to my previous brand. Helps with all my symptoms and the amount given in the package is enough to get you through the toughest days of a cold. There's really no taste and it's great that it comes as a pill and not a liquid.

Works well for cold symptoms

[This review was collected as part of a promotion.] This worked well for relieving my cough, congestion, headache, and body aches. I like that it lasts up to 12 hrs, so I don't have to keep taking medicine throughout the day. Easy to take and convenient for treating several symptoms at once.

Very effective product

[This review was collected as part of a promotion.] This a very good , strong over the counter remedy for cough, cold and fever. I have it always with me during my winters and summers when I generally get cold. It provides instant relief from cold , cough and provides comfort during cold times. Generally very affective when taken at night and go to sleep. It's a very good option for seasonal cold and sickness. Highly recommend

Helpful but hard to swallow.

[This review was collected as part of a promotion.] These came right as my mom wasn't feeling well. She said they've already helped her headache and are making it a little easier to get the nasty feeling out of her chest. Only issue there is is they are pretty large pills.

Works well

[This review was collected as part of a promotion.] Got this just in time for when I got sick. The pill size is decent which makes it easier for intake. My symptoms resolved almost within a day. Would recomm but of course consult with a professional first. :)

Convenient all in one formula

[This review was collected as part of a promotion.] Mucinex 12 HR Cold and Fever Multi-Symptom is very convenient option when several cold and flu symptoms hit at once. I like that it helps with fever, headaches, cough and chest congestion. 12 HR extended formula is very convenient because I don't need to take pills too often. Tablet is a little large is size though. Overall is very convenient all in one formula.

Great all in one relief

[This review was collected as part of a promotion.] This is a convenient option when you were dealing with several cold symptoms at once and do not want to juggle multiple products. I like that it combines help for cough, chest, congestion, fever, headache, and bodyaches and one tablet.

Great product to use while fighting a cold

[This review was collected as part of a promotion.] Great product for when have a cold! The tablets are easy to swallow and are not overly large in size. The taste of the tablet is pleasant. The effects after were helpful with coughing and general discomfort.
