A very good product

[This review was collected as part of a promotion.] I received this product from @Influenster for free for my honest opinion of the product. I used it for several days. I took 2 pills at a time. It helped with my congestion in my chest. It also helped with most of my symptoms. It never made me drowsy. I was alert after taking the 2 pills.

Great for managing cough, congestion, fever, and body aches!

[This review was collected as part of a promotion.] With a 12 hour-formula, Mucinex cold & fever multi-symptom extended release tablets help you feel better throughout the day or night, so you can stay focused on what matters while managing your symptoms!

Great all-in-one cold relief!

[This review was collected as part of a promotion.] Works really well when you are dealing with multiple cold symptoms at once. It helps reduce fever, body aches and chest congestion. It like that it lasts 12 hours, so I don't have to take medication throughout the day.

A high-quality cold and fever medication with convenient 12-hour relief, easy-to-use packaging.

[This review was collected as part of a promotion.] I've been using Mucinex, it's a convenient option for managing several cold symptoms at once, the tablets are smooth and easy to swallow, simple to store at room temperature in a dry place, the 12 hours extended release formula means fewer doses throughout the day , always follow the directions on the package, the product combines a fever reducer and expectorant in one formula, making it a reliable all in one cold medicine, it provides long lasting relief for fever, headaches, body aches, cough and chest congestion , it's effective multi symptom support,

The duration claim si 12 hours.

[This review was collected as part of a promotion.] I received Mucinex 12 Hour cold & flu from Influenster for my honest review. My main symptoms when sick are chest congestión, body aches, and fever, the instructions on the package were clear and the pill was easy to swallow with no aftertaste. I'm testing the efficacy over the nexf few days to see if it really helps with all 3 symptoms. For value.

Definitely works wonders

[This review was collected as part of a promotion.] My husband randomly got a cold for a couple days and gave him this medicine and it worked wonders for him. He took 2 tablets every 12 hours and felt better in about 2 days. This bi-layer tablet helped his cough, aches, and fever. It's made to provide 12 hours of relief for congestion, body aches, fever, and headaches. It's nice knowing you can take this 1 tablet and it will help you with multiple symptoms. It doesn't dissolve so you have to swallow it with a drink. He said it doesn't have a bad aftertaste either which also is a huge plus. Overall we are super pleased with this medicine and going to purchase it in the future.

Throw away your old cold medicine

[This review was collected as part of a promotion.] As a family who always use the typical OTC cold medicine that prevented coughing sneezing runny nose blah blah blah I wasn't sure about this Mucinex 12 hour cold and fever multi-symptom tablet. But I have to say the effectiveness of it was great. Without having to consume the horrible smelling and tasting liquid these pills were in my cabinet for easy storage and after just one dose I started feeling better I am excited to have these in my medicine cabinet for myself and my family.

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

Highly recommend

[This review was collected as part of a promotion.] I really like this 12 hr cold and fever, multi symptom Mucinex. I really like that it's an extended release tablet. I also really like that it's a multi symptom medication, and I don't have to take a lot of different ones.
