The instructions were easy to follow, and a 12 hour formula made it convenient since she didn't need to take it as often throughout the day.

[This review was collected as part of a promotion.] My mom was dealing with cold and flu symptoms, including chest congestion and mucus buildup. I gave her 2 tablets to take as directed. After trying Mucinex 12 HR Cold and Fever Multi-Symptom, she told me it helped loosen mucus in her chest, making it easier for her to clear it. She liked it enough that she asked me to bring it back so she could continue using it while she's recovering. I like the convenience of 12-hour formula since she didn't have to take it as frequently throughout the day.

Effective medication

[This review was collected as part of a promotion.] In fact, I love Mucinex. It is the only product that really has the right dose to help me overcome colds and all their symptoms. Its packaging comes with the perfect way to take the medicine, allowing its dissolution to be more effective.

"Marvelous Mucinex!"

[This review was collected as part of a promotion.] This "Mucinex 12-Hour Cold & Fever Multi-Symptom" Medicine is always fantastic to have on hand! Not only is there the perfect number of extended release tablets in this box, but they are 100% effective. When my family and I are feeling under the weather, it's always good to know that Mucinex is here to help us power through and feel our best, so I would recommend these. Thank you to Influenster and Mucinex!

Immediate relief

[This review was collected as part of a promotion.] I received the Mucinex 12 hr cold and fever multi symptom tablets complimentary to sample. Perfect timing as I have been battling a cold, and these extended release tablets helped alleviate my congestion and loosend mucus. I felt much better after taking these tablets, and it lasted throughout the day to keep me feeling better and able to feel comfortable. Definitely recommend
