Feel Better Fast!
I get the same sinus infection year after year and try different meds. Nothing seems to kick it and I'm sick for more than a week. I tried both the day and night Kickstart and am already behind to feel better. This is it!

No info on active ingredient amounts
Just bought this product. Nothing on either bottle shows the amounts of the active ingredients, just their names. Had to go on line to get that information. Should not be legal to not provide that information on the bottles, and even if it is, why on earth would Mucinex do so?

Effective but not best taste
[This review was collected as part of a promotion.] Love the packaging on this and the pricing is pretty good for a two pack day and night! Although it was sent to me I did have to look up the value. Works really well but I have 4 stars because the taste is brutal but I guess all medicine taste pretty bad lol

So great
[This review was collected as part of a promotion.] Not only is this cold medicine the best I’ve ever used, the value you get it’s worth every penny. I no longer have to search for the best medicine to use when I have one cold and flu medicine that takes care of any and all symptoms. I might have a stuffy nose while my boyfriend has a cough, and we can both take the same medicine and find relief.

Works quickly!
[This review was collected as part of a promotion.] I was sent this to try, but I had to wait until I actually got sick to leave a honest review about this product. And I’m glad I did because this stuff works quick! There was a bug going around the office and I unfortunately had caught it and took this immediately. It helped me sleep through the night and got me through the day with making my symptoms less severe! The taste however, you gotta just hold your nose and swallow. It somewhat has a menthol-y taste to it. But I’m very happy to keep this in my medicine cabinet for when I need it!

Effective and easy to use
[This review was collected as part of a promotion.] This was effective at helping with my congestion and my cough. It tasted okay, medicine rarely tastes great but this one was fine. It was easy to use and a good value.

Good cold meds
[This review was collected as part of a promotion.] This mucinex product duo was great. I was not feeling well and it helped knock out all of my symptoms. The nighttime med was great and allowed me to sleep at night. The flavor was not bad either.

Nighttime version is great daytime is unbearable
[This review was collected as part of a promotion.] I’ll start off by saying the daytime version is horrible. The menthol taste and feeling is enough to make you gag and typically I like menthol. This just lingers in your throat even when you chug water afterwards. I could only take it once and I couldn’t do it again the thought made me sick. The nighttime version is a typical medicinal taste but it’s tolerable. Very little goes a long way and does a great job at helping symptoms but not making you completely groggy the next day.

Fast acting and effective
[This review was collected as part of a promotion.] I've always been a fan of Mucinex as I felt like it worked most of the time. I found these bottles to be on the smaller side but figured if it works then you may not need so much of it, as long as it works, I'm on board. The daytime tastes a bit of the menthol side but when you have a cold, that's good, the nighttime has a more pleasant taste. So far, I continue to stand by the product and I continue to use it during my cold.

Worked well. Would use again for a very bad cold
[This review was collected as part of a promotion.] The daytime one is very minty- which I liked! It helped my scratchy throat and helped to get rid of my nasal congestion. It didn’t make me sleepy at all The nighttime one helped me sleep which was great because of all of my symptoms I was having the hardest time falling and staying asleep. I would buy these again- I don’t usually take medicine unless it’s absolutely necessary. Good value

Effective Relief for Severe Cold & Flu: Fast-Max Kickstart and Night Time
[This review was collected as part of a promotion.] I've been using Maximum Strength Fast-Max Kickstart Severe Cold & Flu and Maximum Strength Fast-Max Night Time Severe Cold & Flu, and I'm thoroughly impressed. The daytime formula provides fast and effective relief, allowing me to power through my day without feeling drowsy. The nighttime formula helps me get a good night's sleep while alleviating my symptoms. Both products work quickly and effectively, making them my go-to solutions for severe cold and flu relief. Highly recommended!

Not for sensitive stomach
[This review was collected as part of a promotion.] The day one gave me bad stomach aches and I stopped using after 2 tries. The night one however worked great for me. It helped with sleep and soothed my throat

Kickstart your cold relief!
[This review was collected as part of a promotion.] This was a game changer for a recent cold bug in our house. It was perfect for my partner who can’t swallow pills and the liquid was easy to take without being too syrupy or leaving a bad aftertaste. The Kickstart kicked in almost immediately with suppressing cough and reducing fever although it did lead to a bit of grogginess/foggy head. The night time allowed for a full nights rest free from coughing fits without leaving a morning “hangover” found in some other options. Highly recommend!
