Mucinex Anxiety Reviews

Mucinex- dizziness, shaking, Anxiety- horrible

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.

I took a Mucinex D extended release tablet and about 30-45 minutes after taking it I experienced a racing heart/Anxiety. My blood pressure was high: 147/99. This medicine works ok, but the side affects are not ok.
Thu, 29 Apr 2010
I took 1 Mucinex DM extended release on Monday and felt like I was on acid about 2 hours later... without the actual fun parts. I was very anxious, experienced a "speed" sensation... always needing to keep moving, couldn't be inside, had to keep myself distracted from what I was feeling and stay preoccupied. This lasted for the entire 12 hours as described on the box. Once I was able to lay down for sleep, I was up most of the night coughing. Then Tuesday, I felt like it was still in my system. I was extremely medicine heady and pupils were still dialated. I still couldn't eat much solid food. I kept to fresh cucumbers and carrots with a few almonds for protien. Now it's Wednessday and I feel a lot better, but still have Anxiety sometimes since I've never taken this before, or any other over the counter drugs like it, and am still not feeling 100%.

I took Mucinex today, two 600mg tablets around 12pm, by 1245p i was having sweats, dizzy, shaking, off-balanced and very anxious. I think the Anxiety was a result of these terrible symptoms I was having. we were eating lunch and i thought i wouldn't be able to walk out of the restauraunt. It was very disorienting and frightening. I haven't taken any other medications but this today.
