Sick medicine

[This review was collected as part of a promotion.] I take this a lot when I'm sick because I can do my normal day stuff! If you want to feel better for 12 hours I would take this it helps so much that way I wasn't sleeping all day long I could do my normal stuff!

convenience

[This review was collected as part of a promotion.] Muncinex 12- hour cold & flu is a must have in my house, especially as a busy mom. As soon as I start feeling a slight cough or headache coming on, I take a dose, and it helps me get back to my day. It's definitely one of those products I like to keep on hand for cold and flu season.

all in one cold and fever fighter.🫶🏻

[This review was collected as part of a promotion.] These extended release tablets are highly effective at knocking out cold symptoms. they quickly relieve intense body aches and headaches while clearing up stubborn mucus and chest congestion. the fact that one does lasts a full 12 hours makes it a must have in my medicine cabinet whenever flu and cold season hits.

Very effective

[This review was collected as part of a promotion.] I received this complementary gift from Influenster and I really liked them. They were fast acting and helped with my cough after the first time I took it. Not everyone is the same, but for me, they were great. Came well packaged. 2 packaged individually so very convenient to have when on the go.

Helped Me Feel Better

[This review was collected as part of a promotion.] Shoutout to Influenster and Mucinex for allowing me to test and review! I love that this combines several cold medicines into one pill, so I don't have to take multiple medications. It absolutely helped with my congestion and body aches and gave me relief for several hours. My chest was feeling tight from all the congestion and this was that only thing that helped break it up so I could get it all out. Just make sure you drink plenty of water when taking it to help break the phlegm up so you can cough it up. Mucinex is always my go-to for when I have a cold.

Better symptom relief!

[This review was collected as part of a promotion.] I am looking forward to using these this winter during cold season. Mucinex has always been my go to for cold medication but now it has Naproxen instead of acetaminophen! The Naproxen will help it relieve pain and headaches symptoms so much better and faster! The tablets are a beautiful pink and white, so they eill be easier to distinguish from other Mucinex products. They are coated and easy to swallow and still offer 12 hour symptom relief!

Works great

[This review was collected as part of a promotion.] Received this free for review. I got this at a good time since there is something going around at work. It worked great, fast acting. It does not make you drowsy. I definitely recommend to anyone who doesn't feel good.

Helped me get through a miserable cold

[This review was collected as part of a promotion.] When I started feeling sick, this was one of the first things I reached for. It really helped with multiple symptoms instead of making me take a bunch of different medications. It eased my congestion, helped with my cough, and brought my fever down enough that I could actually rest. The tablets were easy to take, and I liked that the relief lasted for several hours so I wasn't constantly checking the clock for my next dose. I also didn't feel overly drowsy, which was a huge plus. The only downside is that the tablets are a little large, so they might be difficult for some people to swallow. Other than that, it worked really well for me and is definitely something I'll keep in my medicine cabinet for cold and flu season.

relieves your symptoms quickly

[This review was collected as part of a promotion.] When I received this I coincidentally was going through a cold and coughing. I took the two pills immediately and within hours my coughing stopped until it was time to take it again. It lasted about 12is hours which is great. I am exhibiting no symptoms. Naproxen Sodium is a great pain reliever. Packaging for this is very convenient. You just peel the back and pop it open. And it stores perfectly in my cabinet.
