The flavor was pleasant and not overwhelming. I noticed the product was effective and provided the results I was expecting. The effects lasted a reasonable amount of time, making it convenient to use.

Long-lasting relief for multiple cold and flu symptoms in one convenient tablet .

[This review was collected as part of a promotion.] I was impressed with how well Mucinex 12 HR Cold& Fever multi-symptom worked! It helped relieve my cough, chest congestion, body aches, and fever while lasting for many hours, so l didn't need to take medicine as often. The extended- release formula was very convenient, and the tablets were easy to swallow. I also appreciated that one product addressed multiple symptoms at once , making it much easier to get through the day. I would definitely keep this in my medicine cabinet and recommend it to anyone dealing with cold and flu symptoms.

Great for getting over whatever sickness cold and fever brings on

[This review was collected as part of a promotion.] These meds are serious for any cold and fever symptoms you are facing. They are a pain reliever and fever reducer. The cough suppressing was ultimate! I really needed to not cough at work!. The guafenesin really helps get that mucus up. I highly recommend this! Instructions are very easy to read . The medicine has no smell

Mucinex is a reliable brand I would recommend it.

[This review was collected as part of a promotion.] Good flavor. The table is a little large but it's worth taking. It is easy to find in stores and the packaging was good. Everything is clearly explained in the instructions. Mucinex is a reliable brand I would recommend it.

12 Hour Multi-Symptom Tablet

[This review was collected as part of a promotion.] I've been using Mucinex for years and was excited to try this 12 hour cold and fever multi-symptom tablet. I was recently sick with the flu and this did exactly what I needed it to do. It helped with my fever, headache and body pain. It also helped with the little cough and chest congestion I had going on this product is highly recommended. The taste was doable. It didn't really have a bad after taste or anything like that the texture was nice and smooth.

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.
