This would help you fight a really bad cold

[This review was collected as part of a promotion.] Mucinex 12 Hr is now my go to medication when I get a really bad cold. It helped me with my fever and my symptoms got so much better after a few days of taking these tablets. I would definitely recommend.

Best cold,fever relief

[This review was collected as part of a promotion.] This works great when you have a cold and congested. Loved how it last for 12 hours and works. This will not disappoint if you are all congested,fever,cold. Helped me not be so congested and miserable. The pills are a little big and had to take one at a time, but goes down nicely.

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!!

Quick & Extended in One

[This review was collected as part of a promotion.] I really like that this medication provides both fast acting relief and extended 12 hour symptom control in one pill. It helped relieve my cold & fever symptoms quickly and kept me feeling better throughout the day. I was pleased with how well it worked and would definitely recommend it.

Tested & Proved worthy

[This review was collected as part of a promotion.] My 19 year-old autistic grandson wasn't feeling well and he was complaining of a sore throat and that he had a slightly elevated fever. My grandson did not have a problem with the consistency of the product. He wasn't highly favored of the taste. But I will say this nothing helps this young man feel any better and he complains “ Why isn't the medicine working”? after he takes the product . The Mucinex 12 hour cold and fever multisymptom is one of the only product I have seen help my grandson's symptoms. Thank you so much. 🤗

Nice

[This review was collected as part of a promotion.] Great product. very easy to swallow. Tiny and a little tasty ​Effective relief that actually lasts through the day. It managed my fever and congestion quickly, so I didn't have to keep redosing every few hours. ​Pros: Long-lasting, clears multi-symptoms, reliable brand. ​Cons: Large caplets. ​Highly recommend if you need to stay productive while sick!

relieves your symptoms quickly

[This review was collected as part of a promotion.] When I received this I coincidentally was going through a cold and coughing. I took the two pills immediately and within hours my coughing stopped until it was time to take it again. It lasted about 12is hours which is great. I am exhibiting no symptoms. Naproxen Sodium is a great pain reliever. Packaging for this is very convenient. You just peel the back and pop it open. And it stores perfectly in my cabinet.

Go To Product

[This review was collected as part of a promotion.] This product is my go to when I am not feeling well. I like it because it really does feel like an all in one product. It can help with both cold and flu symptoms, which makes it super helpful for general colds or tougher illnesses. The instructions are clear and the medicine helps very quickly. It has limited side effects.
