Fast Relief When You Need It Most!!

[This review was collected as part of a promotion.] Mucinex does it again!! This formula works with a quickness! It's like a whole body relief, which is so important when having those intense, severe symptoms. No side effects and quick relief!? I'm sold!

Loosens mucus for up to 12 hours

[This review was collected as part of a promotion.] Fever, headache and body pain. Couch plus congestion. Thins and loosens mucus. No taste. Works for 12 hours. No directions listed on package tho. So I have to assume I take one tablet every 12 hours.

Amazing results

[This review was collected as part of a promotion.] We have been battling illness for the last month and these were amazing to have on hand. The pills were a little large, but they kicking in after about 20 minutes. We did find these to be more helpful than regular Mucinex, which says alot because thats our go-to. It helped relieve the sinus pain, lessened the cough, and helped us breath a little easier!

Love this

[This review was collected as part of a promotion.] Perfect for me right now because my allergies sometimes turn into colds in the summer. It is a nice bright package. Pretty simple ingredients. It is convenient to store. The value is high because I have to work!

Kicked our cold quickly!

[This review was collected as part of a promotion.] We ended up with a yearly summer cold from traveling so I was excited to try this product. We are pretty big fans of this brand in our house but hadn't tried this until we got selected to review it. It helped knock out our cold faster than other ones we've tried in the past. The packaging was nice and eye catching if I was shopping for it again in the future. Great product!

The instructions were easy to follow, and a 12 hour formula made it convenient since she didn't need to take it as often throughout the day.

[This review was collected as part of a promotion.] My mom was dealing with cold and flu symptoms, including chest congestion and mucus buildup. I gave her 2 tablets to take as directed. After trying Mucinex 12 HR Cold and Fever Multi-Symptom, she told me it helped loosen mucus in her chest, making it easier for her to clear it. She liked it enough that she asked me to bring it back so she could continue using it while she's recovering. I like the convenience of 12-hour formula since she didn't have to take it as frequently throughout the day.

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.

Really cool feature!

[This review was collected as part of a promotion.] This is actually such a cool product because each tablet has a double layer made for both instant effectiveness and 12 hour extended-release. 12 hours is all-day relief. There's no need for multiple doses. These pills are fairly easy to swallow due to their smooth texture. Plus, I haven't noticed any smells or poor side effects. Keep these in mind the next time cold and fever symptoms decide to give your household a visit!

Fast cold and fever relief

[This review was collected as part of a promotion.] I wish I had this 12 hr cold and fever multi-symptom medicine 1 week ago. I tried everything without relief and was so happy to see this product. I will take this medicine with me when I go on vacation. I love that there is no strong smell and they have ingredients that have inactive ingredients. I feel great to travel soon knowing I have medicine that will target many symptoms.
