Mucinex Palpitations Causes and Reviews


An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.

Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.

Symptoms of arrhythmias include

  • Fast or slow heart beat
  • Skipping beats
  • Lightheadedness or dizziness
  • Chest pain
  • Shortness of breath
  • Sweating

Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.

Mucinex Palpitations Reviews

Fri, 27 Apr 2012

I just got home from the emergency room after taking only 3 doses of Mucinex 600 mg timed released bi-layer tablet. 3 hours after taking my 3rd dose i started with heart Palpitations, racing pounding heart, shortness of breath, my blood pressure has never gone above 115/70 and it was running 138/86 with heart rate consistantly spiking from 105 to 141. They sent me home from the emergency room after 2 EKG's and 2 rounds of bloodwork to make sure I wasn't having a heart attack. I am at home now sitting at the computer and my heart is still pounding and legs are numb and tingly feeling. Nothing like this has ever happened to me before. And to think I was just going to see if it helped with my Fibromyalgia symptoms like I had read how it was helping some people. They need to take this stuff off the market before it really does kill someone. I'm going to try to get to sleep with this pounding heart and I pray I will feel normal in the morning.

I have been battling with some chronic sinusitis (Dr's still don't know if its bacterial or allergic) - so I was instructed to use Mucinex with Afrin at night. I took 2 small drops of Afrin in each nostirl, and 1 Mucinex D tablet and had a horrible reaction. I slept for about 2 hours and woke up with severe Palpitations (115BPM), anxiety, tingling all over my body, and shortness of breath - after trying to calm myself down I got a surge of dizziness, which then immediately threw my heart back into a palpitating panic. This cycle of Palpitations/tingling with the dizzy spells lasted for nearly 6 hours....and left remnants of a faster HR (btwn 85-95) for the remainder of the day. Needless to say, I will not be using this medication again.

First I want to say, I was told by two Pediatricians that Mucinex does not work for kids. They stated that there are no real studies that prove that it works. Now, Mucinex DM (1200 mg horse pill) gave me diarrhea about an hour after taking it. I gave me heart Palpitations that would not stop until after about 12 hrs. of course then follows a horrible headache! $16.00 down the drain. Well, I guess maybe since people are still buying it, maybe Mucinex will be able to get some real studies done and maybe they can improve it. This product is no different than any homeopathic medicine not FDA approved or regulated medicine. Mucinex gets to sell what I think is a bit expensive for being over the counter and no real studies to prove that it works!

Fri, 18 Feb 2011
I took Mucinex DM because I couldn't sleep from coughing chest congestion. I took it around 12:00 amp; fell asleep. At 4:30 in the morning I awoke having the worst panic attack I've ever had in my life. I had cold sweats, heart Palpitations, high blood-pressure, amp; I was in danger of hyper-ventilating. I felt like I had done some powerful drug, amp; was "freaking out". It was a genuinely frightening experience, amp; I will never take this product again. Oh, yeah, my chest congestion was relieved though. Whoopee.
