Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “This medication is NOT recommended! I have severe allergies to the spring weather, and since nothing else was working for me i decided to try this. At first it was like magic my allergies went away no itchy eyes, no sore throat i felt great! the side effects really hurt me though. it was about two days after taking the medication that I suffered a 24 hour migraine along with flu like symptoms, high fever, rashes, dizziness, confusion, racing heart, chills, anxiety, nausea, dry mouth, sleep problems, loss of appetite, and ringing in my ears. IT has been the worst two days of my life thanks to this medication”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “Allegra D has is like a magic pill! This April-May I’ve been suffering horribly from severe allergies and also caught bad viral cold twice!! Also Im terribly allergic to dogs and during that time, my husband also decided to adopt a dog from SPCA. I was literally in bed those two months, taking daily cold and allergy meds (switching b/w regular Allegra/Claritin/Zyrtec) but still has constant sneezing/ itchy eyes/post nasal drip/coughing/congestion, with not even a minute of relief. I decided to take Allegra D for the first time and it’s given me my life back. I’ve been so incredibly grateful for this because it’s worked so beautifully for me. I have zero symptoms of allergies (especially to dog!) and zero symptoms of the medicines side effects. I’ve been taking it daily for 2 weeks. Allegra D doesn’t work for everyone but give it a try b/c it’s saved me and I’m just sooo grateful to be able to function normally now (and saved my rescue dog from being returned!)”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I started taking Allegra D when I moved to North Carolina where pollen is abundant. I began getting headaches that felt like migraines. I went to several sinus and allergy experts even a neurologist. I had several C-scans and X-rays but no doctor could find the problem. Recently, one sinus doctor did. It was an inflammation of the tissue lining in the sinuses. She told me to stop using Allegra D and gave me a prescription for a liquid steroid to mix with saline solution twice a day in a special plastic squeeze bottle with a curved nozzle. It has been a lifesaver. I will never take Allegra D again! Inflammation of the sinus tissue is mentioned as a rare side effect for Allegra D but it should be stressed more.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I've tried other allergy medications but Allegra-D is the only one that works. I used to get constant post nasal drip and have to clear my throat all the time. On this medication I feel amazing. It does however cause insomnia and bad dry mouth. It also makes it so I don't get a full erection. So do I feel better and not have sex or what?”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “Do NOT take this medicine. It should be illegal. I took it for 3 days, and all 3 days I felt nauseous, dizzy, unmotivated, and depressed. Worst part is I haven’t slept more than 2-3 hours a night. This medication will disrupt your life. I usually take Zyrtec D but decided to try Allegra out - my allergies have gotten exponentially worse on it. I have had severe sinus pressure, a cough, and headaches in addition to all the other symptoms.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I only needed to take ONE of these pills to cure my clogged nose. Within hours I could breathe again and I haven’t had a stuffy nose since. Usually I have clogged noses for a week when I catch a cold. I’m so happy I found this.”

Allegra-D 12 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I have chronic rhinitis. I was very ill last year, and my immune system hasn't been the same since. My immune system now reacts to everything around me, i.e. I'm allergic to all of my surroundings: dust, pollen, etc. Instead of the typical runny nose and sneezing, the inner membrane of my nose would swell almost completely shut. I was miserable. Accompanied by a nasal spray, Allegra D was the best thing that's ever been prescribed to me! Although at first I suffered severe insomnia, the side-effects became milder with time.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I tried Allegra D 24 as my pharmacy was out of Claritin D. The 1st few days this really didn't do anything for my sinuses, by day 7 I was suffering from such intense side effects that I could not work, and wound up with an emergency appointment with any Doctor that would see me at my doctors office. My side effects from the Allergra D was anxiety to the 10th power (never had anxiety before), chest tightness, felt like my throat was closing, could not breathe, terrible cough, dry mouth it has been a horrible few days while waiting for this medication to leave my system. I was even give Xanax to help relieve my anxiety, which if you have taken it is no picnic either. I have been taking Claritin D for years and never experienced anything like this.”

Allegra-D 12 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “This medication Allegra-D 12 hr has been for me as close to a lifesaver as it can be. No other medication works for me, without an Rx, of course. I take it once every other day and my nose and sinus remain quiet. I do appreciate Allegra-D 12 hour caller❤”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “Yes, this medication works to eliminate symptoms of allergies, however I had a big issue with - what I'm assuming is - a side effect of the medication. When I took the medication my personality immediately changed; I actually became less talkative and happy and it severely affected my life to the point where I randomly started crying during school. I'm assuming that the medication put me in a depression-esque state (I've never had depression before so I can't say for sure) but it altered my personality in ways my personality has never changed for the three days I took it and people noticed. It was honestly terrifying. Be wary of the side effects when taking this medication.”

Allegra-D 12 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I was suffering from a severe sinus infection for over a week, and I was taking Sudafed to help with the pain and pressure, but of course, that did not work for a sinus infection. I started taking the 24 hour Allegra-D for my congestion and inflamed sinuses along with antibiotics and it helped almost immediately. Every day. I only took it until my infection went away, not continuously. Only side effects were really bad dry mouth constantly and bad drainage of mucous so I constantly had to clear my throat, which caused my throat to be sore.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “Allergra D, is the best medicine for my allergies and I've taken just about every over the counter medicine. I have terrible hay fever and I'm allergic to almost all grasses, trees, pollen in my region (Midwest- Illinois). My allergist suggested that I move to Arizona. Unlike Allegra D 12-hour, I'm having trouble with side effects: insomnia, nausea, heart burn, cramping. The stomach-related effects are beginning to taper off, but the insomnia isn't.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I do not have allergies all year, but just seasonal allergies. When I have flare ups, I have tried everything from Zyrtec, Claritin, Sudaphed, Flonase, Benadryl and the only think that has given me instant relief without knocking me completely out has been Allegra D. It covers my allergies and sinus drainage all at once and I love that it is just a once a day pill. Worth the money by far.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “This medicine works great for allergies. However, day five into taking it, I’m experiencing MAJOR depression/personality changes. I don’t feel like myself at all, and there’s nothing else in my life that would contribute to this. My personality feels extremely subdued, I’m withdrawn, don’t care about anything or anyone, and negative self-talk has significantly increased...this is not who I am! I’ll be stopping this medication tomorrow.”

For Allergic Rhinitis: “Took it around 6:30am before leaving for work. Experienced Terrible insomnia even though I took it early in the morning. Couldn't stay asleep more than three or four hours. Awful stomach pain and loss of appetite. Some itching. Weakness and dizziness when standing too quickly. Dry mouth so I'm constantly drinking water. Unfortunately the other OTC medicines didn't work as well as this product. I'm in a lose-lose situation.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I love this. If I don't take it, I ALWAYS end up with a sinus infection and a trip to the Dr. When I do take it, I don't sleep as well, but I'm not tired in between. My major issue is that I am always constipated when I take Allegra-D and my periods are excruciatingly painful. ”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine): “This medicine is like magic. I had constant post-nasal drip and congestion before I took this medicine. It was so bad I had trouble sleeping because I couldn't breathe through my nose. I also used to get sore throats frequently due to the post-nasal drip. On Allegra those symptoms are gone. I can actually breathe like a human and sleep better. The only side effect is dry mouth but that just makes me drink more water which is a good thing. I am glad this is available over the counter now, but I hate how you only get 10 at a time. ”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine): “I'll never take this again. I took this twice. Decrease in allergies but I would rather deal with allergies than the horrible side effects. This drug made me an emotional wreck both times, extreme insomnia, and have vivid dark, self harming thoughts, even though I am a very happy person. Also was very nauseous. I can't believe this stuff is available over the counter.”

Allegra-D 12 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I was prescribed this medication several years ago for allergies. I was told to take it twice a day. It was effective; however, it did cause insomnia to the point the doctor instructed me to take it once a day. It also gave me headaches the first few days taking it. Other then that, it was highly effective.”

Allegra-D 12 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I have severe pollen allergies and Allegra D was the best medicine I ever took, until I could not sleep. It causes insomnia in me so the trade off is insomnia versus feeling miserable 24/7. It took 2-3 days before I first received relief. Then there was a huge difference.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “It works pretty good. My only two negatives are that the nasal decongestant in this doesn't work as well. I have to supplement occasionally with Afrin nose spray. I would be incredibly miserable without Allegra.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “This medication works great for allergies. My mom takes it and she loves it. However, as soon as I take it, I start feeling all those crazy side effects. Dizziness, nausea, pain everywhere, headaches, crying spells, etc. I personally won’t ever take it again because it is definitely NOT for me but it is for people like my mom. So I don’t know. Maybe it just depends on your body because everyone is different ”

Allegra-D 12 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “When fall sets in so do allergies where I live. After a trip to the doctor I was prescribed Allegra D- 12 Hour, and found that I had the sinus pressure relieved within 2 1/2 - 3 hours. However when drugs.com list states 'dizziness' as a side effect, they're not kidding. I had to get someone to take me home because I (personally) was too dizzy to even walk straight. So if this is prescribed to you I would suggest taking it on a day 'off' such as a weekend, or at night to discover how it affects you personally before you take it on a work day and find out the bad way.”

Allegra-D 24 Hour (fexofenadine / pseudoephedrine) for Allergic Rhinitis: “I've just started experiencing allergies one year ago and only during the winter. I've owned my own business for the last 15 years and a new particular product that I use on my clients triggers my allergies. (There is no other product option for me to use). When winter hit again this year and the symptoms started again. I've tried EVERYTHING Allegra D is the absolute only thing that works! However, I have severe dry mouth, bad post nasal drip, and constant coughing. I use a over the counter mucus release medicine which WORKS! At the end of my work day it's terribly hard to breath so I'm going to try Afin with the Allegra D.”
