Effective and fast acting cold medicine!

[This review was collected as part of a promotion.] My son had a cold, and I decided to try Mucinex 12 HR Cold & Fever Multi- Symptom to help relieve his symptoms. He was dealing with congestion and wasn't feeling his best. After taking the medicine, he started feeling better, and by the next day, I noticed a big improvement in how he was feeling. I was pleased with the results and would definitely consider purchasing again.

Works

[This review was collected as part of a promotion.] Felt like I was a bit sick. with some body aches and just overall feeling crummy. Luckily I had the Mucinex 12- hour cold and fever multivitamin pills that I just received. So I went ahead and took the dose, and I felt so much better within an hour. I will definitely keep this on hand for flu season.

If you are like me and you keep getting cold and fever during the fall and winter season, keep this at hand

[This review was collected as part of a promotion.] I like that when I was dealing with a bad cold and wanted something this really helped me with several of the symptoms at once I didn't have to take several medication. It worked by helping with my congestion, cough, overall cold symptoms and it really gives you a 12 hour relief so you don't have to keep remembering to take something every four or five hours and this is especially helpful at night when you're trying to rest or sleep.

Great for colds

[This review was collected as part of a promotion.] I'm currently sick and I love how I don't get drowsy taking these. Being at home with 3 kids while sick is horrible, but I'm able to keep my headaches down and also reducing my cough and keeping the mucus thin.

Fast working pills

[This review was collected as part of a promotion.] Mucinex 12 hours cold & fever multi symptom works great. Now, when it's a flue season, and school started, lots of people get sick. It's really easy to catch cold. After taking just one dose, I felt imitated relief. I do appreciate Bi-Layer concept, and I can see the result for sure. I will keep these pills in our medicine.

Great to have during cold season

[This review was collected as part of a promotion.] I like that this helps with multiple cold symptoms in one product, specially congestion, cough, headache and body aches. The 12 hour formula is also really convenient when you're not feeling your best

Effective for many symptoms

[This review was collected as part of a promotion.] Mucinex 12 Hour Cold and Fever contains a lot of different medicines to attack multiple symptoms at once. For me personally I always seem to deal with nasal congestion during a cold, and I felt like this didn't address the nasal congestion, but did contain a medicine for chest congestion. It helped with my headache though and cough. Next time I will likely reach for something that contains a nasal decongestant, unless it has shifted to my chest and I need an expectorant.

It really does work

[This review was collected as part of a promotion.] I was really impressed with how quickly Mucinex 12 Hour Cold & Fever worked for me! Within about 30 minutes, I started feeling a noticeable difference. My fever and headache eased up, I was able to sweat out some of that uncomfortable feeling, and my congestion improved a lot. 🤧✨ I'm definitely more of a liquid-medicine person, so my only downside was that the tablets are on the larger side and a little difficult for me to swallow. Other than that, I was really happy with how quickly it helped relieve my symptoms. I'd definitely consider using it again when I need cold and fever relief!
