Guaifen-C and medication

I thought it was just me; this medication is not worth the risk. I thought I was going to die; and it made me very emotional and overly tired. I do not feel like myself.

I started taking Guaifen 3 days ago and i had a hard time sleeping. The first day i felt that my heart was beating very fast and i could not sleep at all. The next night, again, i was not able to sleep even 30 mintues altogether, and during those 30 mintues, i had nightmares. I did not know that this medication can cause sleeplessness until i read the side affects. I knew there was something wrong becuase it is unlike me not to sleep, since i love sleeping.

I was taking guaifen for a sinus infection. I felt like I was dieing. It seemed like I had no blood pressure what so ever, my stomach hurt constantly, could not sleep, headache, awful taste in my mouth and was constantly freezing. I finally figured out that it was the medication causing these awful symptoms. When I looked up guaifen on the internet I was appauled that a doctor would prescribe such a thing!

sensitive to microwave, felt a warm feeling then dizziness after using the microwave while on this medication.

Dr. prescribed guaifen w/p-ephed 600/120mg 2x a day for sever sinus pressure - it certainly has releived the sinus pressure. My side effects have been racing heart beat shortly after taking, upset stomach within minutes and the most problematic has been the feeling of itching on the front of my entire legs, front & back upper torso - especially the upper back and entire scalp as well as waking up 1 hour after taking the PM dose - full of energy - getting ALOT accomplished. However, I am going to stop taking this medication as I want a full restful night's sleep and want the itching to STOP. I personally will never use this product again. Thank you everyone for your input - it helped me greatly. sincerely - sleepy!

My doctor prescribed this medication for a sinus infection. Usually have been prescribed a Z-pack for this by my regular doctor. I took this medication right after returning home about middle afternoon. I was awake untill 5 am went to work and took again in the AM, with my regular morning breakfast of coffee and toast, didn't eat much during the rest of the day, not hungry felt like I was on diet pills (heart palpations, etc. ).
My headache which usually accompanys sinus infections got worse so I went to bed early because it was really a very bad headache and at 5AM I woke up in a cold sweat and started throwing up. After feeling the same at 8AM Since it was Saturday I opt to go to Urgent Care. Was seen by doctor by 9:30AM. By this time I was still throwing up, horrible headach, and cold sweats. My blood preasure was at all time hight 160 over 100. Needless to say this doctor gave me the Z-Pack and he asked to see me again on Monday morning at which time my blood preasure was back to normal 116 over 80.
I will never knowingly take this medication AGAIN! Please note: 1. I have never had high blood pressure, actually it is usually low. 2. When taking medications I will always drink more water than I normally do to help just to flush out my body, especially when I am taking sinus medications as they usually "dry me out".

Have had insomnia for 3 days on this med, after specifically telling the MD (not my regular doctor) that I had trouble with pseudoephedrine. My heart rate was very rapid and irregular. I am also an athelete, and drink tons of water. This medication wasn't in my PDR, so thanks to this web site I have found what the culpret is, and it isn't menapause!!!!

I felt extremely irritable. I had a very rapid heartbeat. I was short of breath, and felt as though I might faint. This lasted several hours after I took this medication. I obviously stopped taking it.

Don't read all of these posts. I personally have not had much of a problem, let me explain...

I think most of these people exaggerate, and their problems are caused by dehydration. When taking this medication you have to drink excess water, not just the daily amount you should already be drinking. The people with serious problems probably drink lots of coffee or soda with caffeine instead of water. This product basically has ephedrine in it, so it increases your heart rate, and caffeine will compound that problem and the dehydration as caffeine has diuretic effects. A lot of these people probably also took a diet pill and didnt tell their doctor, and that will increase the problems substantially, especially if people are also on a low calorie intake diet. It also constricts blood ways, so if you smoke or you have heavily clogged blood ways already you will most likely have a problem.

You can expect to lose weight though, how about that as a positive side effect.

I would bet that 90% of the problem people on here did not follow the directions with the medication.

I run a lot so that makes me tired after I have already taken the medication twice, so I have not noticed much sleep loss, but you should take this with breakfast and lunch not with dinner.

When I took this with the antibiotic I would occasionally experience abnormal heart beats, but when I stopped taking the antibiotic that stopped, probably because I wasn't supposed to be exposed to a lot of sun, and I live in SO CAL. Read the warnings on all of your medication and tell your doctor about all of the over the counter stuff you take including diet pills.

My doctor did not inform me this is a psuedo-ephedrine drug. Which means you should NOT consume caffienated products while on the medication. It could increase the side-effect of dizzyness. The psuedo-ephedrine is also the reason you could feel like "your on speed" or the loss of appetite. Ephedrine isn't for everyone. If you experience those feelings it's best to take a half dose or to stop taking it all. Ephedrine/ephedra are used in many diet pills- most of which are being pulled from the shelves.

When used correctly; modifed to fit an individual, Guaifen can work beautifully.

I've taken this medication a number of times and the only real side effects I've noticed are the upset stomach if I haven't eaten or haven't consumed enough liquids as well as the sleeplessness. I toss and turn all night long and the slightest noise keeps me awake. Sometimes I think my hearing is hightened when I'm on this medication as the ticking of the clock seems abnormally loud. I will deal with the lack of sleep for a week or two if it means I'll get rid of the tremendous sinus pressure I feel.

I was precribed this because I had a bad cold with congestion. I only look the medicine once a day for about 5 days. I've never had a reaction to medication, but this time I did. I broke out bumps that looks like mosquito bites. They're in a few concentrated areas (legs, stomach, forearms). I wish I would have just taken Sudafed to get rid of the cold....

I believe this medication, Guaifen PSE ER, may have been a factor with problems in my left eye. Was on it for a week and began to see light flashes, and then floaters. Had to see my ophthalmologist immediately. It may have raised my blood pressure enough to cause this problem. Will not use it again!

Apparently I'm the only person that likes this drug. If you take it once a day right when you wake up you'll be fine. I get a little shaky. To me its better to be that way then falling asleep and unable to do work. Do not take the drug if you want to sleep. One thing that concerns me about this medication is it constricts blood vessels.

The doctor's office prescribed Guaifen for this inner ear ache. The pharmacist explained that this medication has a stimulant. Since I'm a heavy diet pepsi consumer, I didn't think that Guaifen would keep me awake. After two hours of sleep I awoke and can't go back to sleep. As prescribed, drinking a lot of water goes with the medication; the side effect is frequent trips to the bathroom. Now, its 6am and I wonder when I will sleep again.

was perscribed Guaifen for sinus infection by doctor who wasnt my normal doctor, didnt explain side effects and he needed to....not been sleeping, nasty after taste that leads to vomiting, very nausious......oh yah and you dont take this medication if you are a diabetic, which the doctor didn't bother to check if i was, so now i'm 10 times sicker than i was.....i wouldnt recommend anyone taking this medication

Why I didn't check this forum before getting this medication. I was on it for 3 days (since it did not do anything I stopped). Was prescribed with antibiotics ZITHROMAX.

The next day after I started the treatment, Ilost my senses of smell and taste completely and it's been almost a week and they have not come back yet. This is driving me crazy. Was not able to sleep either during the treatment.

This is the worst drug so far.

I've been taking Guaifen for five days, one pill each day and it's been the worst experience I've ever had with medication. I went for the first three nights without more than an hour's sleep. I swear this stuff has speed in it. Finally I took my Aunt's Zanex and slept for 10 hours. Very irritable, naturally, and severe stomach pains. Whoever invented this medication has a sick sense of humor. I guess that's why they call it practicing medicine. They're practicing and just haven't gotten it quite right yet!

Actually, the med is doing exactly what it is supposed to do. I am a terrible allergy sufferer. This medication has controlled my sneezing, runny nose and all around sinus problems by at least 75%. I strongly advocate this medication. Zero side effects for me.

I can't sleep at night and my heart is beating out of my chest because of this medication.

I was prescribed Guaifen for nasal congestion along with Leviquin for pneumonia. I was told Guaifen might keep me up at night, so I started with just 1 tablet/day instead of 2 and took it twice a day on the weekend. Glad I did as the 1 did keep me awake as well as seem to make my mind race and gave me more dreams/nightmares than usual. On the medication, I wasn't tired but a person needs 6-8 hours of sleep every night, NOT 2 hours. Next time, I will read the side effects before I get my script filled, and call the dr or pharmacist if need be to discuss it further.

I HAVE BEEN TAKING THIS MEDICATION FOR ABOUT 4 DAYS. ALTHOUGH THE MEDICINE HAS COMPLETELY BEGAN TO CURE MY SINUS INFECTION THAT I HAVE BEEN SUFFERING FOR 2 YEARS, I FEEL VERY DRAINED, DRUGED, TIRED BUT NOT SLEEPY AND CONFUSED ABOUT WHETHER OR NOT TO CONTINUE THE MEDICATION. IS IT WORTH IT? I FEEL LIKE A ZOMBIE. I CAN'T EAT OR SLEEP, I AM SO CONFUSED.

This medication:

made mouth and nose really dry (which I guess it is suppose to do considering it is a decongestant)

made me lose my appitite. I don't really want to eat anything.
