All day cold and fever relief !

[This review was collected as part of a promotion.] This is my new go to medicine! I hardly ever get sick but when I do it hits me like a bus. This Mucinex covers pretty much every symptom of the common cold. My body aches went away fever was suppressed and most importantly for me was it helped thin and loosen the mucus allowing me to breathe better throughout the day.

Convenient Lasting Multi Symptom Relief

[This review was collected as part of a promotion.] Mucinex has become a brand I go to for cold and flu relief over other brands! I appreciate the convenience of having both the cough suppressant and expectorant in one dose. Naproxen is a helpful addition for pain and fever relief. The most helpful part for me is the 12 hour dosing. When I'm sick the last thing I want to do is keep track of 4 hour dosing throughout the day!

Provides all day relief

[This review was collected as part of a promotion.] Don't know where I caught my cold during this time of year, but I do know that it wasn't pleasant. The timing of receiving these Mucinex tablets could not have been better. They helped relieve my congestion, fever, and body aches quickly. The 12 hour extended release makes it convenient so that I don't have to re-dose every 4 hours as I would with cough syrups. Also, great that one tablet helps relieve multiple symptoms. Really thankful that these came when they did and worked so effectively at making my recovery quick.

Works wonders

[This review was collected as part of a promotion.] Product works well when you are sick. Helps relieve symptoms rather quickly compared to other products. Will be a product that is kept in our medicine cabinet for future need. The tablets are on the large side but would be a problem for many.

Fast-Acting, Long-Lasting Relief When You Need It Most!

[This review was collected as part of a promotion.] Mucinex 12HR Cold and Fever Multi-Symptom is a great beneficial addition to have in your medicine cabinet. It is an absolute game changer for tackling tough seasonal symptoms quickly and effectively. What stands out most is the long lasting 12 hour relief. It truly helps soothe fever, headaches, body aches, cough and chest congestion without needing constant re-dosing throughout the day. The extended release tablets clear up mucus and ease chest pressure, allowing you to power through your day or get a peaceful night's rest. I received this product complimentary from Influenster in exchange for my honest review, and I will definitely be keeping it stocked in my medicine cabinet from now on.

Pretty effective Pretty effective

[This review was collected as part of a promotion.] This worked pretty well for me. I felt a little better after taking it, and the relief lasted around 10 hours for me. I also really liked that it didn't leave any unpleasant aftertaste. Overall, it was easy to take and helped make my cold symptoms feel more manageable.

Overall, it's a handy product to have in the medicine cabinet.

[This review was collected as part of a promotion.] I've been using Musinex 12hr cold & fever multi symptoms, and it's pretty easy to take. The directions are simple, and I like having one medication that helps with several cold symptoms. It's convenient to keep on hand when a cold comes around.

They work!

[This review was collected as part of a promotion.] These multi symptom pills came at the perfect time! My mother and I are currently going thru a really bad virus and when these came in we decided to give it a shot. Within 15-20 minutes we started to feel less sick and more active. I had a really bad fever and headache and this really helped calm everything down. It does a great job loosening the mucus as well. This a great product and I'd honestly repurchase these!

Good

[This review was collected as part of a promotion.] The timing of the medicine was great. I got a cold from the weather change and it made me feel better within two days. I was feeling better and able to do more than I would have with any other medicine

Easy to take and help ease symptoms

[This review was collected as part of a promotion.] It's back to school season paired with layering weather in New England, so of course I'm sick. I appreciate the easy dose packaging and while the pills are pretty big, they're easy to swallow. They seem to be helping with my cold and I like that they help ease multiple symptoms. Overall, pretty comparable if not better and the long lasting timeline means less medicine needed.
