Mucinex Dizziness Causes and Reviews


When you're dizzy, you may feel lightheaded, woozy, or disoriented. If you feel like you or the room are spinning, you have vertigo. These feelings may make you lose your balance.

Dizziness can have many different causes. A sudden drop in blood pressure or being dehydrated can make you dizzy. Many people feel lightheaded if they get up too quickly from sitting or lying down. Certain medicines and problems with your inner ear may cause Dizziness. So can motion sickness. Sometimes Dizziness can be a symptom of other disorders.

As people get older, they may have more health problems and take more medicines. This makes them more likely to have problems with Dizziness and balance.

Dizziness usually gets better by itself or is easily treated. If you are dizzy often, you should see your health care provider to find the cause.

Mucinex- Dizziness, shaking, anxiety- horrible

Mon, 27 Apr 2009
I am recovering from a night in the hospital after using MUCINEX DM.I was using it for 4 days. Each time I took it I had Dizziness, nausea and lightheadedness, as well as nervousness and nightmares. It was helping my congestion, so my husband insisted that I continue. I should have listened to my body. On the 4th day I took it went to sleep and woke up and felt like my airways were constricted, there was a tightness in my chest, I walked to the bathroom and passed out on the bathroom floor. My husband rushed me to the emergency room. It has been several hours since that happened and my eyes are still hurting, I’m still dizzy and I am still having visual disturbances, and jitteriness.

My elderly father is taking Mucinex and experiencing nausea, vomiting, Dizziness, and blurred vision. After reading the side effects, I'm going to ask that he stop taking the medication and call his doctor. It may be that it's effecting his blood pressure but they doctor will need to check him out.

I took Musinex D one day and that night almost could not urinate. I tried the ove the counter type and experienced shortness of breath and Dizziness. Did not decongest my sinuses. I will NEVER use this brand again.
Mon, 11 Jan 2010
I took Mucinex DM maxiumum strength (12 hour). One pill last night at 6:00 p.m. and one pill this morning at 6:00 am. By 9:00 am, I was having diarrhea. My husband had been taking the regular Mucinex over the last few days and complaining of fatigue, Dizziness, and diarrhea but I just thought he was really sick. I feel like this medicine definitely extended his recovery time. He did not take any at all yesterday and he is feeling much better. :(
Mon, 01 Feb 2010
I took only 1 tablet of MucinexDM what I experienced was Dizziness, a bloated feeling and a lot of gas. The rest of this package will be returned for a refund.
Thu, 18 Feb 2010
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.
Tue, 23 Feb 2010
D A N G E R "DM" 12 hour Awoke with extreme sensation of panic/falling! Day before I actually fell due to Dizziness. I'm a 100% healthy 50 male, in US This is freaking me OUT! Take this shit off the market!
