 3  cold every time I take pseudoephedrine I get relief from my symptoms but always get irritable, spacey, and even a bit paranoid. My wife can tell when I have taken it without me even telling her. M 36 1 days

 1  sinus congestion/sinus headache Excruciating lower back pain which totally incapacitated me for two days. In past, caused disruptions in sleep pattern if taken in late afternoon or evening. Took WalMart brand generic pseudoephedrine HCI 30 mg for sinus problems caused by air travel. Fixed the sinus problems, but caused severe lower back pain. I have bulging disk, but was pain-free prior to taking. Pain went away 24 hours after taking 2nd pill. I don't recommend using this product if you have pre-existing back problems, and urge extreme caution if you choose to take it at all. F 47 1 days

 4  sinus congestion Basically I got seriously high for six hours. At first everything was all glowy and bright outside. Everything was amazingly interesting and the feel of anything I touched was awesome. My inhibitions were lowered and I had a tendency to make a lot of creative connections, albeit expression was occasionally disrupted by slurred speech. After a while it got kind of old, and I got a couple of dizzy spells from standing up too fast. After a while I just wanted it to stop. I don't think I'll do it again unless I'm prepared to spend six hours in bed with a good collection of progressive rock music and a nice selection of snacks. F 23 1 days

 4  cold, allergies, post-nasal drip none I used to take this when my sinuses were especially bad because it was a higher dose than the regular Sudafed. After taking Sudafed for years, it lost its effectiveness, but I could not function without it. I really think I went though withdrawals (chills and hot flashes in addition to the expected horrible sinuses) when I got off this stuff after 10 years. For chronic sinus problems, better to go with an antihistamine that is meant for daily use. F 25 10 years

 4  Allergies & Sinusitis Racing heart beat and palpitations. This medicine worked like a charm. Really helps alot. The only problem is that it gives me heart palpitations. My doctor said I shouldn't take it. Wish I could though, works wonderfully! F 19 7 months

 1  A terrible cold - Xmas 2006 Last year, Sudafed (pseudoephedrine) caused my massive heart attack, and I needed an emergency triple bypass to save my life. I was a lifelong non-smoker, age 37, thin and fit, without any cardiac risk factors. The warnings on the box are totally insufficient; there is no mention that this type of chemical is a vasoconstrictor that can cause artery spasms and lead to blood clots (as it did in my case). Sudafed can have the same impact on the heart as cocaine, and this fact has been documented in the medical literature (Annals of Emergency Medicine, November 2004). It was a devastating experience and I can only urge others NOT to take this very dangerous drug. Keep in mind that an identical chemical (ephedrine a.k.a. ephedra) was banned by the FDA in 2004 for causing heart attacks and strokes in healthy people. Yet pseudoephedrine remains on the market -- you can buy it at any pharmacy for about $5. Why??? How many more people have to die or become injured before the FDA does something? I almost did, and left my two-year-old son without a mother. All because I had a bad cold! F 39 6 days

 1  A bad head cold with congestion Sudafed (pseudoephedrine) caused my heart attack last year at age 37. I am a woman with no cardiac risk factors, thin and fit, and was in perfect health. I needed triple bypass surgery to correct the blockage that resulted from a coronary artery spasm (that's what can happen when you take a vasoconstrictor). This stuff can be as dangerous as cocaine to the heart, but it's still on the market without the proper warnings. I can't state it strongly enough: don't ever use Sudafed or any product containing pseudoephedrine. This was just devastating to me, my husband, and my young son. If it can happen to me, absolutley ANYONE is at risk for a heart attack caused by Sudafed. F 37 6 days

 4  It helped with food intolerences Don't take it too near bedtime as it is a stimulant. If you are sensitive to certain food additives and get headaches and an upset gastro-intestinal tract after eating them , this will help. I only take it once or twice and it clears the symptoms fast. F 62

 3  allergies Anxiety, high blood pressure, dry mouth It is a great decongestant. I used to take it along with my my claritin and also it is in claritin-D. However, my blood pressure went way up due to this medication. It could also make me anxious and agitated at times. It is good for temporary relief but wasn't great for me long term. F 33 5 years

 4  allergies or cold dry mouth Sometimes I need more than my regular allergey medicine, Clarinex. Sudafed is the best for stopping my sneezing. I'm worried now because I was just diagnosed with high blood pressure and I'm not supposed to use Sudafed anymore. F 37 10 years

 5  Allergies, serious nasal congestion I take Zyrtec which makes me sort of tired even though I take it at night but since I have been taking the Sudafed I am much more alert. Growing up I always took Sudafed it was usually the D portion of many of the antihistamines I have taken over the years. For the past 5 years I have not taken Sudafed but have instead used Nasonex or Flonase and they just haven't been doing the job. I have had numerous sinus infections since I got off Sudafed and would have one now thanks to Ragweed season had I not got back on Sudafed. Sudafed is a Godsend, I will be sticking with it from now on. I can breathe again! F 37 3 weeks

 1  Sinus and allergy I took Sudafed and generics for years. I formed blood clots in subclavian arteries and ischemic colitis. Had to have surgery. Doctors -- Stanford University -- and my cadiologist blame Sudaphed. It was part of my life. I did not read the directions! DO NOT USE MORE THAN FOR 7 DAYS. Nose was clear, the rest of me is clogged. Over the counter drugs are not like candy M 63 20 years

 2  Chronic allergies & sinusitis Usually only mild stimulant effect, sometimes jittery and nervous, dry achy sinuses and throat. Recently had ischemic colitis linked to my sudafed use - very dangerous intestinal bleeding! I have taken Sudafed for years due to chronic sinus allergies. It worked very well on my congestion. Recently had intestinal bleeding that required hospitalization. Diagnosed with ischemic colitis, very serious injury to colon, and was told Sudafed can contribute to this because it acts as a vasoconstrictor, making blood vessels tighten up. Ischemic colitis is a rare side effect, but wanted to post here as a caution to others. I'm in good health and never had problems with Sudafed before, never knew this could be a danger. Now, I can never take it again. F 39 15 years

 3  sinus congestion from a cold It dried up my sinuses but left me feeling absolutely wired and jittery with a racing heartbeat. Think caffeine times 50. It was pretty scary. I spent the whole night *wide* awake even though I took this to clear out my sinuses so I could sleep. My mood was also very snappish which is unlike me. I used to take Sudafed for sinus congestion but the last few times I've taken it (and other meds with pseudoephedrine) I've had these reactions. I now rely on Vaporub to clear my sinuses at night when I have a cold. F 23 1 days

 2  sinus problems I hope this review helps.. I come from a family with sinus and allergy issues. Needless to say, during my time growing up, I had experienced some pretty heavy sinus pressure (cough, fatigue, soar throat, stuff head/nose) So my mom put me on Sudafed when I was in about 6th grade. At about that time, I began to develop HEAVY emotional anxiety issues which my parents thought was natural since I was having trouble making friends in school. Not so. Until yesterday, I lived everyday with an extremely rapid heart beat, anxiety, VERY fast and nervous speech, chronic insomnia etc. I had no idea that the sudafed and anxiety were linked so tightly. I figured I was just a nervous, uptight, high strung, and emotional person. Eventually I was diagnosed with depression, and after nothing helped, I quit the antidepressants and saw very little change in my mood. It was then that I began to think that MAYBE the pseudo-ephedrine (remember those crazy diet pills?) were linked to my mood. I recently (VERY recently) switched to Mucinex, which doesn't nearly help as much, but has different ingredients in it (not ephedrine). I'm doing so much better in terms of anxiety and mood. SOOOOO much calmer. The change is incredible. The side effects are CLEARLY the worst part of this drug experience Please use Sudafed with caution. I'm not saying don't use it at all - it surely can be a great help if you ever have a cold or something. But I wouldn't ever use it again past a few days. Too powerful. M 18 7 years

 5  nasal congestion Dry Mouth Works great for a day without congestion. Drink plenty of water. There is a prescription called Entex PSe that contains a high does of sudafed , plus and expectorent. Excuse the spelling. I have been taking it for 4 years. 12 hours pill that not only lets you breath, but helps release the crud in your head so you can spit it out. M 48 4 years
