Helpful when you have a cold

[This review was collected as part of a promotion.] I received this right as I was starting to get a cold, so it definitely came in handy. I feel like it was a little less strong than regular cold and flu medicine due to being a delayed release pill, but still was effective. I would recommend.

Love the 12 hr relief!

[This review was collected as part of a promotion.] I happened to start using this medication the last week because I had a cold and flu symptoms. I like that the 12 hour formula is convenient and means I don't have to keep taking the medicine throughout the day. Overall, it's a good option when I'm feeling congested, dealing with a cough or just under the weather!

My fall and winter must have

[This review was collected as part of a promotion.] I have trusted Mucinex for years, and it is always one of my must haves during cold and flu season. I tend to get sick pretty often in the fall and winter , and this helps me feel better fast. It helps with fever , headaches and body aches , cough and chest congestion, and it also helps loosen mucus. I also like that it doesn't make me feel sleepy, so I can still get through my day. Definitely something I always like to keep at home during fall and winter.

Good product, must try!

[This review was collected as part of a promotion.] Good combination for a chesty cold. The guaifenesin addresses mucus while dextromethorphan reduces the cough relex, so it's particularly logical when you're dealing with phlegm/chest congestion plus frequent coughing. Naproxen instead of acetaminophen. This can be useful if you specifically prefer an NSAID for fever, headache, or body aches. It also means you're not automatically doubling up on acetaminophen if you're taking another acetaminophen-containing medicine.

Trusted brand

[This review was collected as part of a promotion.] These pills are quiet large but they work within an hour. I love Mucinex and I've been using them for years. Not only does this help with my cough but it helps by thinning my mucus and has pain and fever reducer. Mucinex is a great trusted brand

Works wonders

[This review was collected as part of a promotion.] Product works well when you are sick. Helps relieve symptoms rather quickly compared to other products. Will be a product that is kept in our medicine cabinet for future need. The tablets are on the large side but would be a problem for many.

Easy to take

[This review was collected as part of a promotion.] These have been great for my family. Especially with all the weather changing up and down hot and cold someone is always sick. With these they are super easy to take. They start working really fast, which is great and much needed.

Very effective for fever and body pain

[This review was collected as part of a promotion.] Mucinex multi-symptom medicine is very effective for fever and body pain. It helped me with my body pain tremendously. It works for multiple symptoms. My headache was also gone after taking this medication. I think this will be very helpful in the winter time also. I recommend this product to everyone.
