LONG lasting

[This review was collected as part of a promotion.] I was dealing with a nasty cold, body aches, chest congestion, and a fever, and these Mucinex 12-Hour Cold & Fever Multi-Symptom tablets really helped. I liked that I only had to take them every 12 hours, and the extended-release formula kept my symptoms under control throughout the day. The chest congestion loosened up, my cough became more manageable, and I finally felt comfortable enough to rest. Definitely a great option when you need long-lasting relief from multiple cold symptoms.

Loosens mucus for up to 12 hours

[This review was collected as part of a promotion.] Fever, headache and body pain. Couch plus congestion. Thins and loosens mucus. No taste. Works for 12 hours. No directions listed on package tho. So I have to assume I take one tablet every 12 hours.

Effective all in one cold and fever relief.

[This review was collected as part of a promotion.] The mucinex 12 hr cold and fever multi symptom helps with cold, persistent cough, chest congestion, body aches and fever. I liked that it combines a cough suppressant, expectorant, and fever/pain reliever in one product so i didn't have to take multiple medications. The tablets were easy to take and appreciate the connivence of 12 hour dosing.

Phenomenal formula for results

[This review was collected as part of a promotion.] Recently tried Mucinex 12- hour code and fever multi symptom in June I experience cold-like symptoms. I begin using these tablets Swallowing was not that difficult and smooth with the expected smell for Call medicine. The packaging is great and very appealing.

Effective multi- symptom relief that it easy to use and worth having on hand.

[This review was collected as part of a promotion.] I tried Mucinex 12 HR Cold & Fever Multi- Symptom when I started feeling sick, and I was pleasantly surprised. After taking two tablets, I noticed relief from my congestion and overall discomfort. I like that it targets multiple symptoms in one product, making it convenient and easy to use. The instructions were clear and easy to follow. I also think the price is reasobable for the amount of relief and convenience it provides.
