Guaifenex and congestion

My doctor prescribe Guaifenex 600/120 for me yesterday. I had sinus pressure, ears and throat itchy and sore, head congestion. I took one pill at 6 pm, about 20 minutes later I could feel my throat and ears feeling better, and the congestion breaking up and draining. However, the stomach pains and cramps, heart racing, and my blood pressure rose to 153/92. I was so restless I only slept from 9 pm to 10:15pm. No matter what I did, the stomach pain wouldn't go away. Drinking extra water, changing positions didn't seem to help. I'm not tried but I feel so jittery, and restless. The medicine works immediately, but there are some serious side effects to consider.

I've been taking two tablets of Guaifenex PSE 600 twice a day for 3 days and today is the last time I do. I have the flu and so I should be getting plenty of rest, but as tired as I may be, I haven't gotten more than 4 hours of sleep a night since I started this. Normally I can sleep 10 hours at a time with no problem, but I haven't gotten to sleep before 5 am since I started this medication, I wake up 5 or 6 times through the night and can't sleep past 9, latest.

I have never had a reaction to medication before, this is absolutely ridiculous. It's clearing up my congestion but not letting me get the rest I need to get better, so I've just ended up sicker than when I went to the doctor. I'm not pleased at all.

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.

I have noticed tingling in my fingers. I also wake up during the night every few hours. But it makes me not want to eat and that is great! It has cleared up my congestion and gives me energy. I will take it again the next time I have a sinus infection. The side effects are minimal and easy to tolerate for myself. Don't know what is happening to everyone else.

Frl. 05 Nov. 2004 I started taking Guaifenex on Nov. 3, I noticed my heart beating faster, couldn't sleep that night, but was still coughing quite a bit. The next day my congestion was better. I took the 2 pills as stated on the bottle, one at 7am and again at 3pm. What a mistake, I did not sleep at all,very nervous, and with eyes wide open I saw bright yellow balls of light coming from the ceiling. I will never take this again!!!!!

This is the last time I will take this medication combined with P-seudeprine. My doctor prescribed this combined dosasge of medicine to get ride of ear inflammation/congestion but it did not work. Instead it gave me a tinnitus (ringing in the ear) anxiety attack nervousness, panic, elevated blood pressure and insomia. This is the first time I ever had this feelings. DO NOT TAKE THIS MEDICINE unless you have to.

The drug did a great job of clearing my congestion, but it had had a terrible effect on my urine flow. It is almost as if their is a blockage. It also seems to constipate and it is difficult to sleep.

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 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 was suffering with a cough and congestion around Thanksgiving, which waned and came back when my kids inoculated me with the FLU!
I was already dying with the virus, so the "sponge head and tongue" and super dry nosrtils side effects from GUAiFENEX were not too unpleasant.
I did feel bad more from the medication after 4-6 days when the flu was clearing up, so I stopped taking it.
Here I am 15 days after stopping and I am feeling almost normal.
I am glad I did not experience some symptoms of the flu that would have made the GUAiFENEX unbearable to take.

hAd to call doctor and told him that I could not sleep since I started this medication for congestion. He told me to take only 1 pill in morning and eat with it so it would not upset stomach. So I started taking guaifenex at 6:00 am in the moring, have not had anymore problems.

tAKING 1 0R 2 600MG A DAY FOR CONGESTION. NOTICE THAT MY HEART HAS BEEN BEATING LIKE A RACE HORSE. ALSO I DRINK A LOT OF WATER AND MY MOUTH IS STILL DRY, ALSO COUGH SO HARD AFTER TAKING PILL THAT I URINATE ON MYSELF. i AM NOT TAKING ANYMORE. i AM SO GLAD THAT I FIND THIS WEB SITE. THANKS.

My son was given this stuff for congestion. He was feeling ok on Friday and started this med Friday night. Saturday evening the side affects kicked in and include depression, anxiety, dizziness, vomiting, severe headaches, intolerance to light, difficulty urinating, no appetite, sleeplessness, nervousness. Monday morning coughing up and vomiting blood. Great Stuff!

I like this medication so much I gave my daughter and her boyfriend some for their congestion and ear aches. Now they tell me they want to be alone more. I am not sure if the medicine increased their libido or not.

Taking 1 600 mg. pill, twice a day for congestion...no urges to eat at all, makes me sleepy about an hour after taking the drug. BUT...not so unbearable that I won't finish the prescription. I could stand to lose some weight! :)
