Away with the sickness

[This review was collected as part of a promotion.] Easy to open package, these were a lifesaver for my husband who usually gets sick around the first of summer. His usual 2 week long sickness was no where near as bad as it usually is.

Best for cold symptoms

[This review was collected as part of a promotion.] These Mucinex 12 hours cold and fever multi symptom tablets are good for me when I use. It's very easy to swallow, I took water for it. It's good for headaches and body pain.

It works well

[This review was collected as part of a promotion.] I love that it tackles multiple symptoms at once- fever, body aches, cough and headache - without needing a different medicine. The 12 hours formula is specifically convenient.

works great

[This review was collected as part of a promotion.] it works great to break up congestion, especially during allergy season! formulation means it'll last for 12 hours… & it does. the size of the pill makes it a bit hard to swallow

Long lasting

[This review was collected as part of a promotion.] This Mucinex was really effective for fighting cold and fever. It even contained naproxen for pain which I enjoyed. I think this will do the job because it lasts for a long time
