Most effective medicine when you're not feeling well

[This review was collected as part of a promotion.] If you get sick, this should be your go to medicine. It has an excellent pain reliever that lasts for several hours and helps cut a fever. It also has a cough suppressant in the decongestant to help get the junk out of your lungs and get you feeling back to your normal self. Mucinex is the only product I trust when I'm not feeling well.

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!

Eh

[This review was collected as part of a promotion.] It was okay. When I got it. It was crazy because I actually got sick from my kids so lol but it didn't really help any of my symptoms, like at all. I ended up only using it for 3 days till I went to something else but just because it didnt work for me doesnt mean it wont work for someone else!

My cold went away fast.

[This review was collected as part of a promotion.] This mucinex works like magic. I started to feel like if i was getting the cold and i started taking it to see how good this cold & fever mucinex multi-symptom worked, so far in 2 days i was feeling like i was almost without anything. I know that every body is different but in my case this worked really fast for me. Use it as it says, don't take more then what is recommended.

All day relief

[This review was collected as part of a promotion.] This is an essential during cold and flu season. This is fast acting and helps keep my symptoms at bay all day. This does help with the aches and pains during a cold but doesn't completely stop the congestion. Great for colds and coughs that settle in your lungs.

Multi symptom relief

[This review was collected as part of a promotion.] This comes in a pack of 16 tablets and you have to take 2 tablets every 12 hours. The reason I really like this is because it is multi symptom relief. You can use these for cough, cold and for fever as well. I do have to say that if someone has difficulty with swallowing pills then you might want to steer clear as the size is quite large.

My go to meds for a cold.

[This review was collected as part of a promotion.] This Mucinex is my go to when I'm feeling under the weather with a cold. It helps me feel better quickly and relieves all of my symptoms. The cost is reasonable and well worth it to feel better quickly!

Non drowsy

[This review was collected as part of a promotion.] These came at the perfect time. My son was sick and he took these and he was feeling so much better by the next day. They don't make you drowsy like other cold medicines and I would recommend them to anyone.

12 Hour Helper

[This review was collected as part of a promotion.] Once school begins, the flu starts to spread and now everyone in the household is sick. But Mucinex actually helps minimize my symptoms throughout the day! I would say that the medication did a good of suppressing my coughs and congestion.

Strong

[This review was collected as part of a promotion.] This took a while to arrive and I'm not sick so I couldn't tried it yet. But in my experience with the mucin ex products they are pretty good and strong. So strong you only take every 12 hours, I recommend
