Fast-acting multi-symptom relief that lasts and helps you get through cold and fever symptoms comfortably.

[This review was collected as part of a promotion.] This product was very helpful when I had a cold and fever it started working within a few hours and helped relieve multiple symptoms like congestion,headache, and body aches the effectiveness lasted through the day which it easier to rest and function the value is good for 12-hour relief formula especially when symptoms are strong the smell is mild and not unpleasant and overall it was easy to take and consistent in performance.

A total lifesaver when you're dealing with all the symptoms at once!

[This review was collected as part of a promotion.] What I love about this most is the 12-hour relief. You can actually get through a full work day or a solid night's sleep without waking up congested or achy the second a standard dose wears off. It really knocked out my fever and loosened up my chest congestion quickly. The tablets are on the larger side (typical for Mucinex), but absolutely worth the extended relief. Definitely keeping this stocked in my medicine cabinet!

Recommend to everyone

[This review was collected as part of a promotion.] Overall the 12hr cold and fever Mucinex is a game changer and came in during a perfect time while me and my family where sick. We got so much relief from this medicine and there's no taste since it's a pill.

It helps

[This review was collected as part of a promotion.] This Multi-symptom pill actually helped me, it knocked out chest congestion, fever, and body aches within about 45 min and kept it under control for the full 12 hours without making me drowsy. I'd recommend it if you need to stay functional during the day, but it's not for cough with phlegm only since the combo includes pain/fever reducers too. The box comes with 16 caplets, which is a good quantity/size for one bad cold, and I store it in a cool, dry place away from bathroom humidity so the pills don't get sticky.

It is a 12 hour extended release tablet that helps with extreme fever and cold symptoms.

[This review was collected as part of a promotion.] So I received the Mucinex 12 hour cold and fever multisymptom medication. The way this works is that is is an extended release tablet so the tablet will slowly release medicine throughout the day, allowing it to last 12 hours. What the medication does, it helps with fever, headache, body pain, cough, congestion, and thin and loosen mucus. Comes in normal box and each tablet is individually packaged so you can divide them up and take them wherever you need to go. I will say the tablet is a little big. It's about the size of a large Tylenol. So if you're someone who does need a pill cutter to swallow large pills, I do not think you'll be able to cut it because it is extended release tablet. Mucinex is actually a product I've used before especially as a flight attendant as my full-time job it has come to my rescue so now that they have a 12 hour multisymptom relief medication. It's definitely gonna be my next go to travel medicine.
