Long Lasting Relief

[This review was collected as part of a promotion.] Mucinex gave a long lasting 12 hours of relief during my cold. It was very strong and I would recommend it to anyone who isn't feeling well. It's very effective.

Grab on the go

[This review was collected as part of a promotion.] You can ask is always what I grab when I'm stuffy and congested. There isn't a horrible smell or an awful taste. The pill is easy storage and easy to grab! Always works quickly!

Amazing

[This review was collected as part of a promotion.] When I am sick, this is one of the best products to use. It is non-drowsy. The instructions are super easy to follow. I always have this on hand in case I have a symptom.

Good for sinus colds

[This review was collected as part of a promotion.] Works well for what its for. Its fast acting. The only thing I'd recommend is that you swallow the pill as quick as possible. The coating seemed to dissolve fairly quickly.

Great for colds

[This review was collected as part of a promotion.] Great for colds and sinus pain. Helps with fever reducing and just any basic cold symptom. Easy to swallow even though they look pretty big. Decent ingredients and great packaging.

It doesn't work!

[This review was collected as part of a promotion.] I'm going to be completely honest it didn't work! The swallowing was okay. It wasn't dissolvability and Duration sucked! The packaging was good. Would I get this NO because it didn't work!

Convenient medicine

[This review was collected as part of a promotion.] Convenient that it lasts twelve hours and does more than typical mucinex does.. now it's one drug instead of two or three. Pills are decent size but go down smooth

Great medicine for mucus!

[This review was collected as part of a promotion.] I have used mucinex in the past & always have had great results/relief from my symptoms. I don't typically have any issues from the absorption, just make sure I drink lots of liquid!!!
