Mucinex Nausea Reviews

Tue, 06 Mar 2012

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.

Split the Mucinex DM in half and took before reading the box within 1 hour developed high blood pressure, heart racing, Nausea. It lasted for about 5 hours, kept coming and going in waves. Still weak for 2 days. 48 hours later was sitting and had the same effects all over again except more intense. Went to ER and they couldn't tell me anything except I didn't have a heart attack or stroke. Believe me I won't make that mistake again!

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.
