Definitely helpful

[This review was collected as part of a promotion.] The instructions were written very well and easy to understand. It got rid of my headache after about 15min from the time I took the medication and lasted me when I was under the weather. Texture is different with the pill being dual sided but not bad at all. Over all I'd say it's worth the money.

Fast relieve especially for the pain

[This review was collected as part of a promotion.] When I received this product, it was well packed. At first I wasn't sure to take it, because I usually I get heart palpitations, but when I took the pills and waited, no side effects. My husband also love it. One thing that I value was the effectiveness of this product.

Great 12-hour cold & flu relief 👍

[This review was collected as part of a promotion.] This worked really well for my cold symptoms. It helped relieve fever, headache, body aches, cough, and chest congestion all at once. I like that it contains Naproxen Sodium for pain and fever relief, Dextromethorphan to control cough, and Guaifenesin to loosen mucus. The bilayer extended-release tablets lasted up to 12 hours, so I didn't need frequent re-dosing. Super convenient with just 2 tablets every 12 hours.

Highly potent 12 hour relief that is easy to swallow and has no odor

[This review was collected as part of a promotion.] This Mucinex provides amazing multi symptom relief that actually lasts for the full 12 hour duration. The potency is excellent for knocking out a fever and clearing up chest congestion. The tablets are standard sizes, easy to swallow, and have no bad odor. It is highly effective when you are sick.

The tablets are worth it to try. They seem to work pretty fast and they go down easy.

[This review was collected as part of a promotion.] The tablets are easy to swallow with no funny after taste. I did not notice ant smells at all. They store right in the medicine cabinet with the rest of your non refrigerated beds. They last a couple years so I believe it is well worth it to try.

[This review was collected as part of a promotion.] Mucinex 12 hour cold and fever usually works great for me! This one has a medication in it for cough suppressant which helps me when i have a bad cough with a cold or flu. No terrible side effects either!

Works great!

[This review was collected as part of a promotion.] They aren't too big so it makes them easy to swallow and leaves no weird taste in your mouth afterwards. Took this at night and woke up feeling 10x better! Definitely worth getting to help get over a cold/ fever fast.

Convenient 12 HR relief for cough, congestion,fever , and body aches in one product.

[This review was collected as part of a promotion.] I tried Mucinex 12HR cold& fever Multi- Simptomp during a cold , with cough,congestion , body aches and headaches .I like that it combines ingredients for cough , mucus and fever relief in one product , and the 12HR formula was convenient . I helped loosen mucus and made me feel more comfortable while recovering.The tablets are easy to take ,although the size maybe a little large for some people.Overall I would recommend it for multi symptom cold relief .Since these are tablets there isn't really a strong flavor, which I personally prefer over overly sweet cold medicine
