Guaifenex and headaches

My daughter has been sick since October for various ailments. She has asthma (no acute attacks), allergies and asthma. She was hospitalized once for pancreatitis and had strep a week later. She was left with fatigue and, after a while experienced pronounced urinary symptoms. Doctor diagnosed "urine retention" and took her off her Zertec. She has also had problems with constipation and headaches. Last week she was tested out the ying yang for nine things including brain tumor and Celiac's disease. After reading this website, I'm thinking that maybe she just needs to go off the guafinex he's been taking twice daily on the advice of her allergist.

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.

My husband and I have both been prescribe Gauifen/P-EPHED for his congestion and for my ear tubes.
We both experience major drainage at first. It really cleared everything up.
We did however feel the side effects of headaches,light headed ness, rapid heart beats, and we could not sleep at all!
We had to cut the pills in half. The doctors should give people half the dosage if you ask me.
And I read a post about a doctor prescribing this for there child... I would never give this stuff to a kid!
Dont forget to drink lots of water like it says! Good Luck everyone.

I had a wonderful experience after taking this drug. I actually slept better, was more relaxed and for some reason, got all my office work done. All my files were in order and my whole office was organized. I have never been able to work as efficiently as when I was taking this medication. No amount of caffeine compares to this drug! I took one per day. I had no heart palpitations or headaches. I recently found out I may have adult ADD and my physician is very curious to know the ingredients in this drug, as they will be useful in prescribing an appropriate medication for the ADD.

I was given Guaifenex for thick mucus in my sinus, but after a week on Guaifenex I ended up at my asthma doctor, and was told it wasn't my asthme, I needed to go back to the sinus doctor. I was having a hard time breathing, felt like something was sitting on my chest, bad cough, and more headaches. After reading these posting, I am off this med as of tonight. Thaks

I was prescribed this in conjunction with Biaxin for a sinus infection. I have more pain in my head, headaches, light headedness, nausea, and a very lathargic feeling. I also have extremely dry nasal passages. After reading the previous entries I am going to stop taking it. It can't hurt.

major headaches, I vomitted up water, not able to sleep more than a half hour at a time, weakness in muscles

Inability to sleep and really bad headaches that won't go away. Made my head feel worse if anything. Hasn't helped me at all.

terrible nasusea, can't sleep sweating vomitting the day after taking pills will never take them again!! bad headaches too, where I couldn't keep my eyes open.

caused me to loose 24 pounds in 4 days. I can't walk 5 minutes without my heart feeling like it's going to beat out of my chest and it's so rapid at the same time. I get the passing out feeling every time I stand up and then again when I sit down. I've been seeing thing and hearing things. I've had bad headaches from this and voiminting alot. Right now I'm in the stoned state of mind. God help anybody who takes this drug
