Guaifenex and dry mouth

Although it made me a little jumpy and restless, so does caffeine so I didn't think much of it. Since I'm a runner and couldn't wait over a week to do anything, after a few day I tried to go on a short run. Really bad idea. I had extreme dry mouth, I was shivering, uncontrollably sweating, and got really dizzy. Once I stopped and sat down my body became so hot it felt like my shirt was on fire. I didn't feel better until much later and never plan to take this again.

Positive - it worked as far as my constant nose dripping. I've only taken it for three days and I'm happy with the results.

Negative - I have extreme dry mouth and my lower back hurts so bad that I can't lay on it. I must lay on my side. I'm going to increase my water and try cranberry juice for relief. If none within 24 hours, I'm contacting my physician.

Went to the doc yesterday and he said I had a problem with my eustachian tube. He prescribed Nasacort and Guaifenex.

Took one pill last night around 6pm (with a 20 oz bottle of water). I could not fall asleep until 3:30 - 3:45 this morning. Tossed a turned a *lot*. Seemed like I'd go thru stages of being too hot, then too cold. Had intense dry mouth at some point in there. Glad I'm not the only one who seemed to hallucinate. =o/

This morning I woke up at 9:30, took another pill. Felt stoned most of the day. It wasn't until 1:30 pm that I managed to get myself into the shower. Good thing I didn't have to be anywhere.

I took one more pill at 6:30 this evening. I really wish I had found this sight beforehand. I'll definitely call my doctor tomorrow to see if I can just stick to the Nasacort. **sigh**

never took this before & will never take it again. The worst thing i could not pass my urine, i had to go, but had a difficult time. stopped taking it yesterday and no problems today. The other sideffects dry mouth, feeling like i was on speed,loss of appetite. No thanks I'll put up with the sinuses being clogged till it goes away. Also heart beating too fast

A lot of people who are experiencing side effects seem to have been prescribed a high dose of this medication. I am usually severely affected by prescribed medication (dry mouth, hallucinations, seizures, rashes etc- the lot!!!); that other people feel fine off. I don't think pseudophedrine is dangerous unless you have a high dosage. Its like with everything, any medicine can become a poision if you take enough of it. It is probably best to ask for a low dose instead. I'm taking 60 mg and its my first day- feel fine and congestion is loosening.

Been on this for two weeks. I have been very fatigued and have also experienced the dry mouth that so many mention. Perhaps the worst side effect for me is the vision change. I am very sensitive to light and everything is very blurry. I stopped taking it yesterday and I am still somewhat blurry. Hoping this wears off soon. Will be paying a visit to my eve doctor if it doesn't subside by tomorrow.

Took for extreeme congestion due to allergies couple of years ago....sleeplessness, extreeme dry mouth...dazed etc. discontinued use but kept meds. Similar allergy this season....took meds to decongest...didn't seem to decongest but sure did supress appitite. Not a better diet pill on the market! None of the same effects as before. I am a few (20)pounds heavier now....Wonder if the extra weight makes the side effects a little more tolerable?

My doctor prescribed Guaifenex PSE 600 for extreme sinus congestion. I started taking the pills (1 every 12 hours) yesterday. Yesterday morning, I experienced really bad nausea & light headedness. I was able to breathe so much better, the drainage & congestion had really cleared up. I am not experiencing the dry mouth, nor sleeplessness, but I am concerned because this morning I am having chest pain. I'm a bit worried about continuing this medicine. It works soooo good, but don't think the side effects are worth it.

Fatigue and extremely dry mouth - even though I've been drinking lots of water. Now that I am reading these postings I think the fatigue I attributed to the sinus conjestion could be caused by Guaifenex.

After taking this medication for one week I felt worse than before I started. I've had continous throbbing in my head, no appetite, no sleep and extremely dry mouth. I thought this medicine was going to make me feel better. After reading this, I'm throwing them out today.

Incredible dry mouth. Since taking the pill 2 days ago, I've only been able to sleep for 3 hours. I can't fall back asleep but I'm still tired. Sleeplessness triggered a manic episode a long time ago. Be careful.
