Works great

[This review was collected as part of a promotion.] I work at hospital, I had been feeling run down for few days, like I was coming down with a cold. Before bed, I took two tablets of Mucinex 12 hours cold & fever and body pain multi- symptom. When I woke up in the next morning, my body pain was gone and I feel much better overall. A great Value to have on hand when cold systems start to appear.

12 hour cold and fever

[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!

Helps kick sickness faster

[This review was collected as part of a promotion.] Honestly, when a bad cold hits, I don't have the energy to keep track of taking medicine every four hours. That's the main reason I grab this specific Mucinex 12HR Cold & Fever—you take it once, and it actually keeps working through the day so you can function. It covers all the basics (fever, body aches, and a bad cough), but it's especially good at clearing out that heavy, stubborn chest congestion. ​If you're building a sickness survival kit, definitely keep a box of this and some decent tissues on hand. It saves you from having to run to the store when you're already feeling like trash.

Love

[This review was collected as part of a promotion.] Can you packaging is 10 out of 10 it is convenient on the go and to put it in your purse. Side effects. Just a little sleepy but it goes away fast. I do want to say that it helps you feel better after 30 minutes of use

A top-tier cold and fever relief option I would choose again and again, hands down!

[This review was collected as part of a promotion.] I got sick this summer, and this helped me manage my symptoms so I could get back on my feet and handle what I needed to do for work. The tablets were easy to take and swallow, and I appreciated the convenience of 12-hour relief during a busy day. I also like having a multi-symptom option on hand rather than needing to reach for several different products the ingredients were designed to address multiple cold symptoms, and that was so convenient. Based on my experience, I would recommend it for keeping in your medicine cabinet when cold and fever symptoms come up. I did receive this Mucinex 12-hour cold and fever multi-symptom complimentary in exchange for my honest review. I would choose this again and again because it truly works.

A Great Option for Cold and Flu Season!

[This review was collected as part of a promotion.] Mucinex 12HR Cold & Fever Multi Symptom provided long-lasting relief from multiple symptoms in one product. It helped with cough, congestion, body aches, and fever while making it easier to get through the day. I appreciate the 12-hour formula so I didn't have to take medication as often. A great option to keep on hand during cold and flu season!

Family Favorite

[This review was collected as part of a promotion.] When the common cold hits our home, we always turn to Mucinex for fast symptom relief. Their long lasting symptom relief and several options for different types of colds is what keeps us coming back to them when needed.

Really good

[This review was collected as part of a promotion.] I want to start by saying that suddenly getting a cold the day before I received this was weird juju lol I took this sample for a "juat in case" moment but here it was. It didn't cause palpitations, works well for 10-12hrs. Did not cause drowsiness and I like that it has fast release and a longer lasting one. Also, no weird dreams.

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
