Worked well!

[This review was collected as part of a promotion.] This worked really well for my cough and headache. I didn't have any flu symptoms but it worked well in relieving the cough and headache I got from coughing. The pills were easy to take and seemed to last as long as it says on most of the days I took them! All around I would recommend and would reach for it at the store when needed!

relieves your symptoms quickly

[This review was collected as part of a promotion.] When I received this I coincidentally was going through a cold and coughing. I took the two pills immediately and within hours my coughing stopped until it was time to take it again. It lasted about 12is hours which is great. I am exhibiting no symptoms. Naproxen Sodium is a great pain reliever. Packaging for this is very convenient. You just peel the back and pop it open. And it stores perfectly in my cabinet.

Mucinex 12 hr multi-symptoms is convenient and dosage helps keeps those symptoms away for more amount of time

[This review was collected as part of a promotion.] My family has been sick due to rainy spring weather and today it was my turn. I woke up feeling a bit of a headache, congested and some body aches. I took it this afternoon once I received the product and feel better already. Althought the pill seems big, if you drink enough water it becomes easy to swallow. The pagaging and dosage makes it easy to not forget to take the medicine. If I need to take it at night I can have the pills next to my bed stand and a bottle of water. I feel better already and it hasent been 6 hrs.

Works fast!

[This review was collected as part of a promotion.] This came in handy at the perfect time. I'm not one to get sick all but when I do I need something that gets me back to normal fast! As a mom, I can't be down for the count! This Mucinex did the trick and within about 24 hours I was back to normal!

Convenient 12-hour, multi-symptom cold and fever relief that helps manage cough, congestion, fever, headaches, and body aches in one product.

[This review was collected as part of a promotion.] I was impressed with the packaging and clear labeling on Mucinex 12HR Cold & Fever Multi-Symptom. The extended-release formula combines naproxen sodium (110 mg) for fever, headache, and body aches, dextromethorphan HBr (30 mg) to help suppress coughs, and guaifenesin (600 mg) to loosen and thin mucus. I liked that it provides up to 12 hours of relief, making it convenient during the day or overnight. It helped target multiple symptoms in one product, reducing the need for several medications. The value is good for a multi-symptom treatment, though users should be aware of potential side effects such as stomach upset, dizziness, or drowsiness depending on individual sensitivity. Overall, it's a convenient option for managing cold and flu symptoms.
