Long lasting!

[This review was collected as part of a promotion.] These worked great when I was feeling under the weather recently. I've always been a very big fan of mucinex effectiveness when I am ill but this one is seemed to work longer and did not make me feel groggy. Pills were a bit chalky but that's really my only complaint

Wiped my cold away so quick!

[This review was collected as part of a promotion.] I had been feeling really crappy with a cold, and this Mucinex 12 hr cold and fever medicine knocked it right off. It helped ease my headache, body aches and congestion. And even better ,it didn't make me drowsy! And so glad I didn't have to keep taking it because it lasted 12 hours. The Instructions were easy to follow and I only had to take two and it was easy to swallow without leaving a chalky or gross taste . If you are dealing with multiple cold symptoms at once this is the medicine worth keeping in the medicine cabinet.

All in one 12 hours relief for fever, cough and congestion.

[This review was collected as part of a promotion.] This worked really well for me during a bad cold. One tablets covers a full 12 hours,so I didn't have to keep track of multiple medications throughout the day. It brought my fever and headache down quickly, eased my cough, and helped loosen chest congestion so I could actually clear it. The tablets were easy to swallow and didn't upset my stomach. With 16 tablets in the box, it lasted through my whole illness. Definitely repurchasing for the next cold season.

Best fever, cough medication

[This review was collected as part of a promotion.] Mucinex 12hr cold & fever multi-symptom worked really well for me. They helped relieve my headache, reduced my overall discomfort, and made it much easier to breathe. I also love the 12 hr convenience since I didn't have to take medication as often.

Highly recommend to keep in hand

[This review was collected as part of a promotion.] The box had clear instructions on how many to take. It wasn't to hard to swallow with plenty water. It didn't have any bitter after taste. It's easy to put away and great size. Can have it in medicine cabinet and won't take much space.

Last up to 12 hours so you dont have to take medicine throughout the day

[This review was collected as part of a promotion.] I started taking Mucinex 12HR Cold & Fever Multi-Symptom as soon as my cold symptoms started, and it made a huge difference. It helped relieve my cough, loosen the mucus, and reduced my body aches and headache. I also love that it lasts up to 12 hours, so I didn't have to keep taking medicine throughout the day. Definitely a great product to keep on hand during cold and flu season! Highly recommend. 💙

Great for congestion

[This review was collected as part of a promotion.] I was gifted this item for my honest review. As a household that has a child in daycare, we are constantly dealing with colds. This came in time for us to try on the recent head cold we had. It worked very well to give us relief from the major symptom of congestion. Taking the pills was very easy and we followed the dosage schedule on the packaging. As this is not a liquid, there is no aftertaste. Also, I am happy to report the duration of this head congestion was relieved quickly and I am feeling much better.

Cold and fever relief

[This review was collected as part of a promotion.] Mucinex is always a go to when we have some congestion. I luckily have not been sick since I received these to try but my mom used them and helped relieve her cough and congestion. They were easy to swallow and liked that they last for 12 hours.
