Worked great and only had to take once a day for a couple days!

[This review was collected as part of a promotion.] I didn't realize how great they were going to be, until we went on vacation and came back with cold symptoms. These helped my adult daughter get through the day and feel semi normal. She only had to take one dose a day for a couple days. I took for the same amount of time, no weird taste and easy to take. Packaging was cute for a medicine. These are easy to store in the cabinet. No trouble with dissolving.

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!

Effective 12-hour relief for cough, congestion, fever and body aches in one convenient product.

[This review was collected as part of a promotion.] I recently used Mucinex 12HR cold & fever multi-symptom while dealing with a cold that included fever, body aches, chest congestion and a persistent cough. I liked that it provided long lasting relief and helped loosen mucus, making it easier to breathe and clear congestion. The cough suppressant also helped reduce coughing, especially at night. The tablet were easy to take, and I noticed symptom relief within a few hours. Overall, this is a convenient all- in -one option for managing multiple cold symptoms and helped me feel more comfortable throughout that day.

Effective relief for chest congestion with a surprisingly pleasant taste.

[This review was collected as part of a promotion.] I used mucinex when I started experiencing cough and chest congestion. The consistency was easy to take, and the taste was much better than I expected for a cold medicine. After a short time, I noticed it helped loosen mucus and made it easier to clear my chest. The ingredients are commonly used for congestion relief, and I found it effective in reducing my symptoms. The bottles was easy to store and the dosing instructions were clear. Overall, I had a positive experience and would consider using it again when dealing with congestion.

Relief

[This review was collected as part of a promotion.] Mucinex is the only thing that really help me with mucus build up when I am si k and congested. This helped me with the congestion, and qll over body pain. It didnt make me feel sleepy so I could still keep going. It helped for the 12 hours but getting closer to time to take the next dose I did feel it helping a little less. Overall though it really does help with cold symptoms well.

10-10

[This review was collected as part of a promotion.] I will for sure be repurchasing these. I live in the mountains and went on vacation to the beach, once I got back from the beach I ended up super sick. These helped make me feel so much better. I was able to rest and able to breath so much better.

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!

Love this for cold

[This review was collected as part of a promotion.] The best thing for a cold! I love that it's for 12 hours instead of the usual 6-8, so I can sleep and feel great all night without waking up and coughing. It does not expire fast but it does absorb fast, within 30 minutes I felt so much better.

Works quick!

[This review was collected as part of a promotion.] I unfortunately got a bad cold in late spring but was glad to have this new 12 hour Mucinex cold & fever multi-symptom! The tablets were easy to swallow and my symptoms lessened during the 12 hours. Being in less discomfort helped me be able to get back to work and life quickly.
