 1  Congestion it cleared up my congestion, but i had absolutely terrible side effects after. i had this sudden wave of anxiety and i felt dizzy. my heart was pounding, i literally thought i was having a heart attack. and despite the fact that i only took one pill (the proper dosage, and this was my first time taking it today), i was fearful i had somehow overdosed, like i wasn't "congested enough" or something. i'm at least comforted by the fact that i'm not alone in this experience. this was terrible. they need to put a warning on the box for this. this is the first time i've had side effects from sudafed. needless to say, i'll probably avoid using it from now on. 1 days

 1  24 hour Destroyed me, my sleep and gave me anxiety nervousness that are lasting till this day. I was the most relaxed person no nasal issues just 2 weeks allergy and pharmacist gave me this instead of the antihistamine. Destroyed my nose as inflamed my turbinates which I had no issue as had surgery 30 years ago. Was in perfect health 100/60 BP HR 55. Have spent 70,000 dollars to find how to cure what it's done. Been on countless meds. This is a POS. Have been on benzos now antipsychotics and ssri things I have never even heard off to cure me of what this awful drug did to me. I don't drink or smoke or take anything but vitamins and 3 antihistamine pills a year. M 53 6 days

 3  Sinus and Ear Congestion I sleep with a CPAP and it causes sinus and ear congestion. My ENT prescribed Pseudoephedrine 120 for the congestion and dizziness. It works fine, but the side effects are horrible. I took one pill at 0630 and 2435. My anxiety is through the roof. I'm just not sleepy and I have a rapid pulse. M 41 2 days

 1  Sinus and ear congestion Extreme anxiety, shaking and shivering, restless legs, high heart rate. Took at 5pm Made me feel so sleepy at first but due to all the other symptoms I listed, I couldn't sleep I just tossed and turned. Finally slept about 2 hours and then was awake from midnight on with horrible insomnia. Next day all day still had the anxiety, fidgety and restless feeling I will never take this again. Worst 48 hours of my life. Also want to note, ive had these symptoms before when taking sudafed but just didn't realize it was the cause and now I know without a doubt. F 33 2 days

 1  Allergies I only take this pill 1x per day and I notice that before taking it, the congestion is slighlty there, but after taking it, I feel groggy and then after 2 hours of taking it I feel strange, the pressure around my eyes and nose is incredibly uncomfortable. I feel distant, edgy, nervous, one of my eyes is twitching. I can't focus and it is uncomfortable to keep my eyes open. I will no longer take this pill, I've never known what it feels like to almost loose it, but with this pill, it almost feels like I'm about to scream my head off. Be careful with this pill.

 1  Seasonal Allergies I had intense loss of appetite, nausea, vomiting (I couldn't keep even a sip of water down), headache, feelings of anxiety, loss of control, and sweaty, pale, clammy skin. The worst symptoms lasted about 4 hours and began to drop off right about when it would have been time to take another dose - but I will never take this medicine again. F 35 2 days

History
 1  Sinus drip Took 12 hour max relief at 2:30pm. It's 3am and I'm wide awake, restless, jittery, itchy and feeling very wired and irritable. I've had a tightness in my head all day and a feeling that something bad may happen to me. I even alerted family members as to what I took and how I'm feeling. My hearing seems to almost be magnified with slight ringing at times. I have a tightness in my chest at times and feel winded. I'm very uncomfortable with this feeling I've had all day and into the night. I will not ever take this again!! I wish this would all just stop and go away!! I don't recommend this-esp if you have a sensitivity to any medications!!! F 50 1 days

Heart raced. Terrified the whole night. Felt like I was really, really high. I'm extremely wired and can't sleep at all. M 18 4 days

 4  Chronic Nasal Congestion Odd taste in mouth, perhaps headache, but that could be aggravated by coffee. This medication works well for nasal congestion. I was getting caffein headachs that reduced when I switched to water after two cups. But I can't tell if headaches are resulting from Sudafed or some other medication I'm taking, such as amyltriptalein or prozac. M 68 30 days

 1  Sinus congestion I took a 30 mg yesterday, about 36 hours ago. I am still feeling the effects, and they seem to have worsened somehow. I have anxiety, feel like something terrible is happening or about to, sweaty cold hands (which never happens to me). Since I didn't take any sudafed today I am pretty surprised this is happening, but I'm positive its because of the sudafed. Yesterday I felt a little jittery, very cold, and somehow dissociated from life in general. Stayed up way too late. Slept for 6.5 hours and felt mostly ok for most of the day. Drank coffee in the morning. I still had the cold hands feeling, but thought little of it. My nose got pretty stuffy again. I lied down. Slept for about 5 minutes. Got up then drank coffee. My sinuses cleared again. Had lightly spiced pho for dinner. SInuses cleared completely. The impending doom feeling gets more noticeable, cold hands and nose, muscles easy to cramp. I can't believe this is all happening from a single 30 mg pill I took 36 hours ago!!!!!! Th I know I rambled. I don't know what else to do. Be careful with this stuff. F 36 1 days

 1  Flu/sinus I was worried I was having a stroke or onset of MS. Rapid heart rate, confusion, nervousness, jittery legs, felt like I was going crazy. It increased my anxiety. I was about ready to call 911 until finding this site. I do not recommend and it should be removed from the shelves. F 47 5 days
