Guaifenex and headache

I took one pill and fifteen min. later I started having a pain in my stomach. I thought, well maybe I didn't eat and drink enough, so I drank another glass of water even though I'd eaten a good size meal before taking med. Five min. later the pain switched from stomach to chest and back pains, but mostly in my chest. Also, my finger nail beds turned blue and I could not get warm and had chills. My heart did not seem to be racing and was steady, though I did get a mild head ache. At the peak of the pains it radiated up my neck and lower jaw, and no matter how I lay I could not make it go away.

I experienced a sudden feeling of overwhelming exhaustion during the whole ordeal. Symptoms persisted for a few hours, didn't stop until shivers had passed and by then I had a temperature of 100.7 when I previously had none whatsoever. I think about 96.6 was my average before that. The next day I was extremely tired and unaccountably restless.

The only other med I had been taking was a 24 hr. Alavert that dissolved on the tongue... it didn't even have a decongestant in it. CVS lady said there was no reason I couldn't take it along side the Guaifenex. Now I'm not sure what to believe. It scared me enough that I don't think I would ever risk taking it ever again.

I was given an antibiotic and Guaifenex 600, twice a day. It affected my urination pattern. I would have a need to go but in the beginning very little urine would come out followed by more but not near the force as normal. Afterwards, I would always have the feeling that I had not emptied my bladder. I thought something may have been wrong with my prostate. I drank a lot of liquid during this time. I stopped but continued to drink a lot of liquid hoping to get it out of my system. About one day after stopping, I urinated normally.
I took both for ringing in my ear and an ear infection. Neither helped my ear infection. I also experienced a headache which I usually do not have.

My doctor prescribed me Guaifenex for a sinus infection along with trimethobenx for upset stomach along with advair ( a powder inhaler) never knew why she prescribed all of this medication just for a sinus infection. I stopped taken the advair an experienced shortness of breath, bad headaches, but one things for sure I only eat one meal a day. Oh by the way I can't sleep at night and extremely tired in the morning to start the cycle all over again the next day. It leave a very nasty taste in my mouth i'm constantly brushing my tongue it leave a coating on it. The drainage I can never cough up and my ears has been clogged since I started these meds. I take tylenol pm just to sleep. Something to think about before taking this medication. You get it for a sinus infection but end up with a headache.

I took this with a sinus infection and fluid on my ears - second time to take the Guaifenex for the same illness. It said very clearly on the bottle to take with a full glass of water and believe me, if you do not take with a full glass of water, the meds don't work properly at loosening up the mucos and you will get a headache. Lots of headaches are caused by dehydration anyway. But I think many of you who have complained of a headache would find if you drank more water when taking the pills, it would go away. It is also a little harder to fall asleep but no harder than it is when taking OTC Sudafed. So I would recommend the Guaifenex - it works great at breaking up the junk that causes the infections.

I took my first guaifenx tablet yesterday and have yet to go to sleep! Not only was my heart beating out of my chest - I was experiencing the worst headache I have ever had in my life. I will NEVER take another one of these horrible pills again and I am amazed that my doctor perscribed this medication for me.

I was prescribed this drug for an upper respiratory infection. I definitely couldn't stay at work after taking it & had to go home! Felt light-headed, dizzy, but it did make the cough go away and has helped me sleep. I've been taking it for a week now and somedays I experience an annoying headache that lingers around all day. It does the job, but I would definitely recommend staying home if you're gonna take this drug.

Unable to sleep, headache, loss of appetite, don't know if I'm having hot flashes or feeling is caused by Guaifenex. Called pharmacist after first sleepless night, was told to just take one pill in the morning and discontinue the second pill. Still not sleeping. Am stopping medication after three days.

I got a splitting headache 2 hours after taking1200mg tablet

When i took 1 pill it was so bad that i couldnt take it again. I was halucinating and had a very bad head ache. I couldnt sleep very long and everytime i woke up i was very dizzy and hot. I will never take Guaifenex again.

I experienced headache and loss of appetite. Also caused me to be sick to the stomach.
