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.

Mucinex, cold and fever tablets are amazing!

[This review was collected as part of a promotion.] The Mucinex 12 hour cold and fever release tablets are great! I have been using regular Mucinex for years and it really does help get all of that mucus out. Now that it's meant to help with other symptoms is amazing!

A total lifesaver when you're dealing with all the symptoms at once!

[This review was collected as part of a promotion.] What I love about this most is the 12-hour relief. You can actually get through a full work day or a solid night's sleep without waking up congested or achy the second a standard dose wears off. It really knocked out my fever and loosened up my chest congestion quickly. The tablets are on the larger side (typical for Mucinex), but absolutely worth the extended relief. Definitely keeping this stocked in my medicine 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.

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

Sick Days No More!

[This review was collected as part of a promotion.] This brand new product really helped when I was dealing with congestion, cough and body aches!! I loved that it combines multiple symptom relief into one product and provides long-lasting 12 hour support without needing constant repeat dosing. My cough was calmed and I was put at ease overall when using this product on sick days!

Gets the job done💯

[This review was collected as part of a promotion.] I've had a terrible cold for a few days now, coughing and phlegm after taking this I started to immediately feel better within the hour, you take 2 tablets every 12 hours as needed & it really helps!!
