Really efficient

[This review was collected as part of a promotion.] These Mucinex bi-layer tablets for cold and fever are good, their effectiveness is excellent it makes you feel better after taking two of these Mucinex, and the relief effect is excellent it longs around 11 to 12 hours, I recommend this for when you are not feeling well

Mucinex is my go to when sick

Easy option for multiple symptoms

[This review was collected as part of a promotion.] This arrived with perfect timing, my whole house has come down with summer colds. This has kept me going while I try and prep for a vacation and get things done at work. The combo of the multi symptom keeps me from having to track what I've taken and whose taken what all day long. I do wish the pills were a little smaller but they are manageable. Will be adding to our medicine cabinet as a family that gets sick often.

A convenient, long-lasting option for managing multiple cold and fever symptoms

[This review was collected as part of a promotion.] It is convenient when you're dealing with several cold symptoms at once. I liked that it provides long lasting relief and helps manage congestion, cough, headache and fever without needing to take multiple different products. It's easy to take and convenient to keep on hand during cold and flu.

Large pills, but worth it!

[This review was collected as part of a promotion.] This marketing team knows their seasons. My sample of this came right when our house was in the middle of our inaugural “welcome back to school” cold case. Seriously, with five littles it is inevitable. I've never sprung for the time release version so I was excited to see if there was much of a difference. My cold had moved into my lungs and no amount of coughing or humidity could give me any relief. These did; once I could swallow the dang things anyway. They're large pills, but the package says you can't break them, not a fan. I'd say it took about 30 minutes to kick in because around the. I suddenly felt like I wasn't dead. It's nice to have a one pill for multiple symptoms. And while it didn't get rid of my cough entirely it did sound less severe.

Convenient and needed.

[This review was collected as part of a promotion.] These came in two packs of 8. Not huge tablets either, which are perfect for someone like me who has the worst time swallowing pills. These came right on time for the cold and fever my family just got hit with.

Works Great!

[This review was collected as part of a promotion.] I was super congested and achy before taking this. Once taking it, I started feeling relief in about 30 minutes. It really helped with all of my symptoms and I even felt myself get better quicker than I normally would.

S mucinex!

[This review was collected as part of a promotion.] This is a brand we all know and trust. Can't go wrong with it. 12 hours is a beautiful amount of time to have symptom relief for. 16ct is a great amount of tablets as well. It's a classic excellent brand thus you really can't go wrong

It Works!

[This review was collected as part of a promotion.] My 12 year daughter got sick with a fever and chills on the second day of school and this Mucinex product was a lifesaver. She was feeling better within and hour and then up and moving a few hours after that. I appreciate that it is a 12 hour product to cut down on how frequent you need to take. She also was minimally coughing which after she took I didn't hear at all. I think this is a very good product when you have the specific symptoms and highly recommend to keep on hand!
