I love mucinex

[This review was collected as part of a promotion.] I love this medicine!! I got the flu and it set up in my lungs! This medicine is amazing, it broke up the phlegm and I instantly felt so much better and didn't feel like I was dying. I love that this medicine doesn't have ibuprofen in it. I will always get this medicine when I get severely sick. I love it!!

Works amazingly!!

[This review was collected as part of a promotion.] I ALWAYS trust mucinex when I'm sick!! It helps loosen up the mucus, helps with the random aches and helps with all coughing that comes with it!! It definitely helped this summer with the summer colds.

Sick day necessity

[This review was collected as part of a promotion.] I was sent these right in time to save us from a cold, they really do work, drank them once I felt a little congested and had a cough and felt way better by the end of the day, must haves for fast relief 👌

Super useful for colds!

[This review was collected as part of a promotion.] Mucinex is a must have in our medicine cabinet. This version for cold and fever really canners in handy at the end of the school year. My husband was really sick but was able to take these as recommended so he could function, work and help out at home without feeling like he was falling apart.

Multi-Symptom relief, great medicine cabinet staple

[This review was collected as part of a promotion.] I received this product to review, but thankfully no one in my family got sick while I had it! Because of that, I was unable to personally test the effectiveness for cough, cold, congestion or fever symptoms. I really like that it's designed to provide relief for multiple symptoms in one product. Having something like this on hand is very convenient when it all hits at once!

Don't sleep on Mucinex

[This review was collected as part of a promotion.] Mucinex 12-hour code and fever multisymptom medicine is amazing. Anything Mucinex always comes through. No foul taste, easy to swallow, dosing is always clear, and the medicine does what it says it does: eases your symptoms and always gets rid of that nasty junkie congestion.

Long lasting relief

[This review was collected as part of a promotion.] Summer colds can be just as miserable as winter ones! I used mucinex 12hr cold & fever relief when I was dealing with cough, congestion, and body aches. I liked that it provided long lasting relief. It helped loosen mucus and made my cough manageable.

Works well!

[This review was collected as part of a promotion.] Unfortunately cooties and germs still get me even in the summer. I love how quick this works at helping me feel better. I hate the taste of so many liquid medications so I really appreciate that this is a pill!

Not recommended

[This review was collected as part of a promotion.] These Day & Night Cold & Flu medicine helped reduce my cold symptoms, such as congestion and body aches. However, I experienced severe side effects that made it difficult to continue taking them. After using the medication, I had intense dizziness, nausea, and overwhelming anxiety. While it may work well for some people, my experience was unfortunately very unpleasant because of these side effects.
