Within ten minutes of taking the recommended dosage, I had a tingling feeling that started in my chest and raced into my head. I felt VERY light-headed and then my heart started beating very fast and very hard. I started drinking glass after glass of water and these symptoms slowly sub-sided. When I called Walgreen's to tell them what happened the pharmacist told me, "Well, don't take it any more....

Within one minute of taking the Mucinex my tongue and throat started tingling and my heart started pounding. Very scary. I will not use again. Although, now that it passed it has loosened the congestion.

I had to switch to the cap form. The liquid made me up-chuck. It has a high sugar and lots of sodium 12 mg a shot! I would not recommend this for a diabetic. I'm not diabetic but, the glucose test made me vomit because of the sugar. Something to keep in mind.

When I called Walgreen's to tell them what happened the pharmacist told me, "Well, don't take it any more...and, by the way, you can not return the product to the store." I am no longer a customer at Walgreen's. They are un-caring and do not care if you die or not. I DO NOT recommend this product to anyone and I DO NOT recommend anyone shopping at Walgreen's because they really do not care for their customers, they only want YOUR MONEY.Read More Read Less

I was having some congestion and started taking this product. After the second day, using it twice a day, I had a strange reaction, sort of tingling and numbness in all four extremities, nausea, sort of a "disconnected" feeling. It was very disturbing, happening while I was in a grocery store, and I barely made it back to the car while holding tightly to the cart. It took 4- hours to feel normal again. I am afraid to try it again, although it did loosen the mucus.

I took three doses of this medication over a 12 hour period with a full glass of water with each dosage. I woke up in the middle of the night with pain in my bladder and found that I was bleeding as I urinated.

I have taken one dose, at bedtime. Slept the night through. Woke up and fell from severe dizziness. 17 hours later I am still dizzy if I move too fast. My cough has been more productive all day, and I am coughing less.

It have tried this medicine twice. Each time after 6-9 minutes, I develop horrible stomach ache/cramps that last about 4-5 minutes. Horrible feeling. I noticed that is only the Fast Max one.

I had been taking Mucinex 600 mg for a few days and felt I needed to start on something stronger so I purchased Mucinex DM and did not read the directions and started right off by taking two pills every 12 hours and did so by taking 6 pills in a 36 hour period. When I awoke this morning I was very dizzy and could barely see correctly. I was in a sad shape but I immediately re-read the directions on the box that says one pill every 12 hours and I had been taking two. A quick warning to anyone that would be a terrible mistake taking more then one every 12 hours. I was very close to going to our ER and after sleeping 6 hours I felt much better.Read More Read Less
