Guaifenex and pseudoephedrine

I took this to try and help some rather chronic sinus congestion. I only took one or two doses (it was a few years ago), but became really ill. I have palpitations normally, so I didn't notice that. However, I was leeched of energy and ended up spending half the day vomiting or feeling like I had to. I was cold and clammy, which is extremely abnormal for me. According to my coworkers, I looked pretty darn bad. I somehow made the long drive home (I wouldn't recommend) and tried to sleep. Eventually I passed out for a good 8 hours, but still felt yucky the next day. Naturally, I haven't touched the stuff since. To be fair, these side effects are listed under the drug info (online), but who thinks they are going to be in the small percentage affected? Also, in response to an older post, it's NOT pseudoephedrine. It is the ingredient in mucinex and a decongestant similar to or found in the "new" crappy sudofed. I've been taking pseudoephedrine for years with no problems. Glad I found this! I thought I was the only one!

This is merely time released Sudafed. You people on here who have all these crazy problems are ridiculous. If Pseudoephedrine is such a problem to these people, I dread what other simple drugs like aspirin or Maalox must do to you.
Anyone with half a brain knows that you need to drink lots of water with this drug. If you don't, you will encounter extreme dryness and head / bodyache. Just as well, it doesn't take a genius to read the common side effects of Pseudoephedrine before taking the drug. The things people are reporting here are typical common side effects. What is this, 'the uninformed alarmists' forum or what?!

Then do you not find it strange that all these people have had the same symptoms? My husband had been experiencing horrible side effects for days before he finally asked me to find out something about this medication and I came across this site. I had taken this medication last fall and had the same horrible side effects. I didn't lay eyes on this website until the day I posted his side effects, June 13.

In some cases, yes, people may read about these problems and begin to imagine they're having the same ones. I can vouch that we had these symptoms before seeing this site, and we were shocked that so many other people were experiencing the same things. Sudafed may have the same active ingredient, but Guaifenix may have it in a stronger concentration, or it may contain other ingredients that cause people to react differently to the pseudoephedrine. Who knows?

Whether you take Guaifenex or Sudafed 12 Hour, you're taking the exact same chemical: Pseudoephedrine. This is the chemical which makes these medications work. Go look at a Sudafed 12 Hour package and see for yourself.

And I'm sorry, but nobody's been hallucinating or vomiting blood from taking Sudafed tablets.

Pseudoephedrine is okay for most people, just not for you people. When was the last time we all had our lives destroyed by Sudafed? Get real: thousands of people take Sudafed and never have problems. Pseudoephedrine is not a problem for me.
