Helpful medicine

[This review was collected as part of a promotion.] I used Mucinex 12 HR Cold & Fever Multi-Symptom for cough and fever. The 12-hour dosing was convenient because I did not need to take it as often during the day. It helped loosen mucus and reduce my cough, and I felt more comfortable while resting. Be sure to follow the label instructions.

Worked very well

[This review was collected as part of a promotion.] I have been really happy with the Mucinex 12hr Cold & Fever Muti-Symptom medication. It is very convenient to have one medication that can help with several cold symptoms at once. Love that the medication is dosed every 12 hrs, this makes being compliant with medication so much easier than having to take it frequently. It really helped me with my last cold, I will keep it handy going into this next cold season.

Best Cold and Fever medicine to have

[This review was collected as part of a promotion.] This is the best Cold and Fever multi-symptoms medicine ever, it works instantly and up to 12hrs. Just finished using this and got over my cold pretty fast and I'm glad to stock up more of this especially with the winter season is coming up.

Mucinex cold and fever

[This review was collected as part of a promotion.] Started using this after experiencing cough and headaches. Within a couple hours I was already feeling better. It helped to suppress my cough and get rid of my headache and lasted longer than normal cold medicine does. Will definitely continue to use when I'm experiencing cold symptoms!

Fast-acting and long-lasting multi-symptom relief for cold and fever!

[This review was collected as part of a promotion.] Mucinex 12 HR Cold & Fever Multi-Symptom worked great for me when I was feeling under the weather. It helped reduce my fever and headache, cleared up chest congestion, and quieted my cough without needing to take pills every few hours. The 12-hours extended release made a huge difference, especially overnight, allowing me to rest comfortably and get through the day much easier. Highly recommend keeping this in your medicine cabinet!

Best cold and fever reliever

[This review was collected as part of a promotion.] This 12 hour cold and fever multi symptom reliever really worked. I took a full dose, which is two tablets with a full glass of water since this is a time extended release tablet I felt better my cough and fever went down.

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

I highly recommend

[This review was collected as part of a promotion.] I highly recommend! The instructions were very clear and the convenience of the packaging was also easy. It's a foil back so you can easily pop right out of the packaging. I ended up getting a cold last week and this was a life saver. It helped me sleep through the night without coughing my guts out.

It works fast!!

[This review was collected as part of a promotion.] This product came in the perfect time! I am a registered nurse and I have been getting vitals and taking care of sick kids all week. Today I woke up stuffy and congested with the terrible headache and cough. I took two of these pills as stated in directions and two hours later I feel so much better. I'm able to blow out a lot of the congestion as my mucus has loosened a lot! Headache is also gone and the cough has lessened. This could be my new go to for cold and fever. Thank you Mucinex!!!
