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

Use two pill every 12 hour

[This review was collected as part of a promotion.] I received this medication from influencer and I tried it when I have fever at work and it's really good it's easy to take and the relief it was quick I highly recommended for everyone. And the packaging it's good too the texture it's good. Also, it's good for a dry cough.

Longevity is the key for symptom relief

[This review was collected as part of a promotion.] Mucinex is a trusted brand in our medicine cabinet so when I had the opportunity to try this out, I was happy to give it a go. I really like that this formulation helps with symptoms for up to 12 hours. I think that is super beneficial for our lifestyle, especially for myself working a corporate job and for my husband who works 10 hour shifts with a 1 hour commute. The 12 hour relief is exactly what we need. The ingredients being in pill form make is super convenient and easy to take on the go. Thankful that we have a product like this in the market that will help us with cough, congestion, fever, and body pains for an entire shift at work!

Fast relieve especially for the pain

[This review was collected as part of a promotion.] When I received this product, it was well packed. At first I wasn't sure to take it, because I usually I get heart palpitations, but when I took the pills and waited, no side effects. My husband also love it. One thing that I value was the effectiveness of this product.

Medicine that provides long lasting relief

[This review was collected as part of a promotion.] To say I'm impressed with the lease. I started taking it as soon as I noticed my cold symptoms were worsening up and from helping my body aches feel much better for my headache, headaches diminishing, and my chest congestion getting some relief I am absolutely thrilled to be taking them when I definitely need them. I really highly like that. The medicine lasts up to 12 hours so i didn't have to keep taking them it really helps Luz mucus, makes it easier to cough it up and ultimately makes breathing much more comfortable. The only thing is it's the tablets are slightly a little big, but other than that, I absolutely love how efficient they work to help fight a cold

Immediate Relief

[This review was collected as part of a promotion.] I caught whatever bug is going around and took these on day 2 of my symptoms. I felt so much better! These pills are not big and don't have a chalky aftertaste. It started working immediately and lasted all day. I made it through my work shift and honestly forgot I was sick!

Good solid medicine option

[This review was collected as part of a promotion.] Good option for sickness. I like it has everything in one so you can take it and forget about it. It does well lasting the 12 hours. The instructions are clear to follow. No bad smell. No negative side effects to note. I like it

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.

New favorite to have at home for a simple cold

[This review was collected as part of a promotion.] Oddly enough I caught a cold after receiving this and it helped me unlike anything, consulted with my doctor friend and he said go ahead, those sound good, and I'm glad cause they definitely did the trick! My cold symptoms were significantly reduced in 2 to 3 days.
