Relieves Symptoms and Helps To Recover From A Cold

[This review was collected as part of a promotion.] The 12HR Cold & Fever Multi-Symptom Medicine by Mucinex is perfect for getting rid of symptoms from a cold. The tablets are easy to swallow and aren't too big in size. I like that these are extended release tablets, which is great for long-lasting symptoms. I've been feeling with a summer cold lately, and these have come in handy. Since taking these, I've noticed a decrease in my fever and a decrease of pain relief from an annoying headache I've had the past few days. I also feel like it has reduced mucus, and I'm feeling confident that I will see more loosening of the mucus. I have experienced any bad side effects since taking this. I'm glad to have a dependable supplement to ease and get rid of the symptoms from this cold!

Best med for congestion

[This review was collected as part of a promotion.] The best medicine for cold and flu! Mucinex is the go to for congestion in our family. I don't know what it is, but it seems to work better than the generics. With school back in session, it was just a matter of time before someone got sick. My son and husband both came down with something last week. Cough, congestion, headache, and just generally feeling yucky. Negative for flu and Covid, just a nasty cold. This medicine helped them actually sleep at night. The decongestant was fast acting and long lasting. They even only took one pill and that lasted all night.

Effective, hard to swallow, but EFFECTIVE

[This review was collected as part of a promotion.] Let me tell you that these are big pills. BIG. They are definitely not super easy to swallow however they are extremely effective. These 12 hour multisymptom, relief, cold and fever pills get the job done. It truly does zap symptoms for a full 12 hours. Highly recommend if you need an exporant, it does also eliminate all flem.

Helps with cough

[This review was collected as part of a promotion.] This is the stuck to take when you're sick. The combination of DXM, guaifenisin and naproxen in the extended release format helps keep me more comfortable all day long. It's a good all in one solution.

Effective and efficient !

[This review was collected as part of a promotion.] This medicine is very effective in relieving the heaviest of cold symptoms . I received this right when school began so I put it to use because my home was under the weather. It most certainly worked beautifully! It's a very effective and efficient medicine to go to for relief!

Easy to take.

[This review was collected as part of a promotion.] I received this item free for my honest review. I have been using this for two days and I tell you I feel so much better. The pill is easy to swallow and doesn't get gritty going down your throat. The box is easy to find at any store. I will be sharing this Mucinex 12hr to everyone.

Effective & Reliable Relief

[This review was collected as part of a promotion.] I really liked the Mucinex 12HR Cold & Fever Multi -Symptom extended release tablets as it lasts and is effective. I could rest without having to dose frequently and it covers a multitude of symptoms by taking 2 tablets. They were easy for me to swallow and yes they are slightly larger but I didn't have any difficulties nor aftertaste. This is a great product and great value as you don't have to take so many pills or remember when you took them as it covered everything I needed and lasted 12 hours.

Overall high quality medicine

[This review was collected as part of a promotion.] These mucinex 12 hour multi simple tablets work pretty well. I received them and conveniently i was already under the weather so it worked out nicely to test. I will say they overall worked great! My only complaint and the reason they dont get 5 stars is the taste. I generally prefer gels for this exact reason but they do work great knocking down your symptoms. Id recommend if you arent super particular about taste of medicine.

Great combo

[This review was collected as part of a promotion.] This is really great addition to flu season. Mucinex with cold and flu so you don't have to take too many tablets. Usually we are takin mucinex separately and cold and fever tablets separately but with this we can take in 1 tablet. Great convenience.
