Amazing product from another Amazing brand.

[This review was collected as part of a promotion.] I had always been a consumer of Mucinex products well in the past ranging from syrups and now these tablets. My experience specifically with this has been quite positive. I would say it is a fast acting tablet that provides with relief from fever and headache while also loosens mucus making me feel less congested. The tablet size are not too large so I can can swallow them with ease and without discomfort. I am thoroughly impressed with the relief from my symptoms and will continue to support the Mucinex brand.

Mucinex 12hr cold and fever

[This review was collected as part of a promotion.] Typically I don't like to take Mucinex products due to its combined properties, I rather just take the individual ingredients, this way it is more effective. however, after trying this, my cold went away completely after 48 hours.It is extremely effective and the short term relief is also fast. I plan to continue using this product in the future.

Great for tackling several cold symptoms at once

[This review was collected as part of a promotion.] I like that this Mucinex covers several symptoms in one product instead of having to take a bunch of different medicines. The 12 hour formula is really convenient too because I don't have to keep thinking about taking another dose every few hours. It helped with congestion and made it easier to clear mucus while also helping with the headache and body aches that come along with feeling sick. The tablets are a little big but I was able to take them without a problem with plenty of water. Overall this is definitely something I would keep in the medicine cabinet for cold season.

Good product/large pills

[This review was collected as part of a promotion.] You can never go wrong with mucinex. It's a product must have, especially during sick season! My husband is always sick and so I make sure to have a large supply of cold products and this is both of our ‘go to' the pills are a little large which isn't a problem for me but I could see it being an issue for someone who has a hard time swallowing pills.

Cold be gone!

[This review was collected as part of a promotion.] Mucinex is next level when it comes to cold and sinus meds! Their 12 hour cold and fever medicine worked like a charm when I was feeling bad. It alleviates body aches and helped reduce my fever quicker than some other medicines I've taken in the past. This does loosen chest congestion and mucus so you may notice an increase in cough from this. Overall I would recommend to quickly snap out of any cold or fever symptom!

I can't wait to get a cold!

[This review was collected as part of a promotion.] OK, I have used Mucinex products in the past and they have usually worked pretty good. This is a new product that has just come out and I would really excited to try it the first time I get a cold. The packaging is fairly easy to open, and the pills are dual layered so they give you that extra help that lasts a while instead of just wearing off after about three or four hours. For this to come, especially at the beginning of cold and flu season, this is going to be a godsend. I'm a teacher, so after summer break, my immune system needs to build itself up! This will be great because I can take it in the morning and don't have to take another dose at lunchtime, like usual cold and flu products.

Mucinex never disappoints !

[This review was collected as part of a promotion.] I have used the Mucinex products before, but this helped immensely during a round of colds in the house. In no time at all I felt much better, as did the rest of the family. I would definitely use this again.

Fast relief

[This review was collected as part of a promotion.] As a healthcare worker I am exposed to cold causing viruses everyday. Even with proper protection I do tend to catch a cold every few weeks. However, I am able to still get back to work with a 12 hours turn around time with rest and this product.

Great To Have Handy

[This review was collected as part of a promotion.] I like having this on hand whenever I'm dealing with a bad cold. It's nice being able to cover several symptoms with one medicine instead of taking a bunch of different things. The 12-hour formula is convenient too, especially when I'm trying to rest and don't want to keep track of doses all day. Definitely something I'll keep stocked in my medicine cabinet.
