Mucinex Feeling Abnormal Causes and Reviews


Chiari malformations (CMs) are structural defects in the cerebellum. The cerebellum is the part of the brain that controls balance. With CM, brain tissue extends into the spinal canal. It can happen when part of the skull is too small, which pushes the brain tissue down. There are several types of CM. One type often happens in children who have neural tube defects. Some types cause no symptoms and don't need treatment. If you have symptoms, they may include

  • Neck pain
  • Balance problems
  • Numbness or other abnormal feelings in the arms or legs
  • Dizziness
  • Vision problems
  • Difficulty swallowing
  • Poor hand coordination

Doctors diagnose CM using imaging tests. Medicines may ease some symptoms, such as pain. Surgery is the only treatment available to correct or stop the progression of nerve damage.

Mucinex Feeling Abnormal Reviews

Tue, 28 Feb 2012

I bought Mucinex 12 hour expectorant with 600mg of guaniffesein. I thought this was suppose to thin out the mucus and help expel the phlegm. Instead I experienced a terrific headache, sinus pressure in my ears , and it dried up all my mucus (like using an antihistamine) that I never had any productive cough or expelling of phlegm! I also drank herbal teas with lemon and honey and homemade vegetable soup during the day and sipped on tea all day long. I was so dried up and headachy that I had to use steam from a boiling pot to help open and moisten sinus airways. After a while I decided to eat a lot of real food to help absorb the potency of this formula. NEVER NEVER take this! I returned it to Walgreen's and got my money back. Instead of helping my cold, Mucinex made my whole day un bearable!

Do not take Mucinex if you are allergic to sulfa drugs. My son is highly allergic to sulfa and has had several reactions while taking Mucinex over the last 6 months. We just found out that it was the Mucinex and not any other exposure that was causing his hives/rash/itching/swelling/etc. This last reaction was worse than any other reaction he has had. After the Mucinex was out of his system he began to get better. Now we are warning all our friends and family - Dont take this if you have a sulfa allergy!

Had a very bad cold with an unrelenting cough. Took Mucinex DM on pharmacists recommendation. First night was great, slept didn't cough as much. continued with medication.
Second day -Started feeling unusually sleepy/ cold /weird headache loose bowels nausea odd feelings Put it down to the cold getting worse. Second day read box for side effects. NONE I was having. Day three -Now horrible cramping diarrhea, nausea and dehydration though drinking clear fluids non stop. becoming irrational and hypersensitive, face felt slightly numb. Finally checked the internet and found this.Soon as stopped, much better. Still have a cold, but I don't care. Lemon, honey and Irish whiskey working much better for me.

great stuff

My lungs are failing and I believe its from 3 doses of Muscinex dm. I had Bronchitis and took Muscinex on advice from my Dr. A week before that I had quit smoking, so now that's all anyone pays attention to, but while I smoked I NEVER had any lung problems. I quit because I got tired of the smell around me, not because of any physical problems. I have never had any excess mucus, in fact I have never coughed.
Twice now I have been unable to draw in breath and have had to be hospitalized. One of my nurses agreed that the drug may have glazed my lungs, and that's exactly how they feel now. My voice is raspy and I lose it completely every few days, usually from trying to have a conversation.
I am seeing a pulmonary specialist who has me on Spiriva until tests are finished but neither that, Albuterol or Flovent have any effect on how I feel. I am extremely short of breath when talking on the phone or even walking to the car. I have gained 20 lbs from my inactivity and that doesn't help.
Muscinex has changed my life drastically, and may be what ends it. That stuff needs to be pulled.

Thanks everyone for your input! I had sinus infection and was put on antibiotics and Mucinex DM. Had blurry vision and was very dizzy. Thought it was the antibiotics. PCP changed me to a different antibiotics not realizing it was the Mucinex. My last dose of Mucinex was Sunday and my eyes are still dilated.....blurry vision. Mucinex made me so dizzy, I couldn't stand up. I weigh 98 lbs and so the side effects are lasting a lot longer. So glad I found all your comments.....this helps!

My husband was taking Mucinex routinely for COPD to thin the heavy mucus, but after about 3 weeks, he began having serious mucusy coughing fits, then had emotional bouts. After reading this site, I had him stop and the problems cleared in about 15 hours.
