For Allergic Rhinitis "I took two 180-mg doses of Allegra for hay fever on two consecutive nights. The day after the first dose I experienced mild, intermittent nausea and reduced appetite. The morning after the second dose I was bed-ridden for 3 days with severe nausea, intermittent sweats and chills, aberrant thoughts and dreams, and headache. I did not vomit or have diarrhea nor did I have an abnormal temperature. As I write this on the fourth day I am just getting up and eating a little. This was like no stomach flu I've ever had -- I feel as though I have been poisoned. I firmly believe that my illness is a side effect from the Allegra."

For Allergic Rhinitis "I suffer from chronic sinusitis caused by allergies. I also had a bad case of bronchitis a year and a half ago and 3 respiratory infections since. I have tried a bunch of antibiotics, Claritin D, Zyrtec, Bendryl, Mucinex, Singulair, cough syrups and other OTC decongestants, herbal supplements, steroids, and the Neti Pot. Only the Neti Pot helped me feel better for an hour or so and washed away a lot of the allergens but the sinus inflammation and bronchial irritation due to post nasal drip returned fast. I just started using Allegra 3 days ago and the difference is remarkable. I can breath again! I also sleep better and I don't feel tired all the time. I have not experienced any side-effects so far."

For Allergic Rhinitis "Allegra stops the drainage and the annoying need to clear my throat (post nasal drainage). But I'm dizzy these last couple weeks since I've started it. I have a mild sore throat and headache, which I experienced previously when trying Allegra. I feel tired, nauseous and have had a strange tingling in my legs occur twice this week. I'm thinking Allegra is not a good choice for me, despite its effectiveness."

For Allergic Rhinitis "I have bad allergies to a lot of things. Food, dust, animals, pollen. The list goes on. While at the doctors office, he gave me a 5mg Xyzal. It cleared up my nose within the hour and I could breathe the rest of the day. The doctor suggested taking Allegra 12 hour. So I bought some, and planned on taking it the next day. That night I was really tired before bed. Went to sleep. I woke up about 7am and stayed in bed almost the entire day. I was completely drained of energy. At 3pm i took the Allegra . The package says “non drowsy”. By 4pm I was so weak I felt like I was getting anesthesia. I had to be at work by 5pm. I drank some tea, hoping the caffeine would help. For the next few hours I struggled hard. I was completely drained of energy and my head felt foggy. It was horrible. At the 6 hour mark, I was less tired. Woke up today and decided not to take another one. What a nightmare that was. So much for “non drowsy”"

For Urticaria "The "new" Allegra Hives tablets are exactly the same ingredients as the Allegra Allergy tablets. The only difference is you get fewer tablets for more money. Keep that in mind before you think about buying the "new" Allegra Hives."

For Allergic Rhinitis "Took for about a year for Allergic asthma allergies before I realized when I ran out and started something else that I no longer need a walker to walk and I regained all the strength in my legs!!! The whole time l was told no one knew why I slowly lost my ability to walk or function and even my allergist never suspected the Allegra but once I stopped the drug my weakness went away…horrible horrible"

For Allergic Rhinitis "I had been suffering from THE WORST hay fever for 3 months. I'd been to 5 different doctors and have been on umpteen different meds. Finally, the last doctor suggested I try Allegra. Within the first few hours I was feeling wonderful! Allegra is a fast acting, powerful medicine! So thankful for a doctor who knew his stuff! This will definitely be bought every allergy season!"

For Urticaria "I have eczema which cause awful flare ups on my hands and caused my skin to get dark . All the topical steroids I applied did not help heal the skin neither did it change the color. However with one allegra a day my skin instantly looked and felt better. Also, it always cures any respiratory allergies as well. I truly recommend this medicine."

For Allergic Rhinitis "It seemed to me the reviews here were overly negative for Allegra. For me, Allegra has the fewest side effects. I've never had any drowsiness issues with Allegra.I have noticed that it takes about two hours to get the maximum benefit although starts to work in 20 minutes. It does lose potency after 7-8 hours. I sometimes cut the pills in half so can you extend the effect a little longer. It does provide excellent relief. For extreme pollen levels, I think Zyrtec or Xyzal are a little stronger. But, I would try this because it seems to less side effects if you have not been a regular antihistamine user."

For Allergic Rhinitis "I have been an allergy sufferer for a long time. When I started taking ALLEGRA 24 hrs. it worked just fine. But, the problem is that this medication works as intended it work for 24 hrs. straight and it keep you awake for 24 hrs. Too. So, if I take a pill of ALLEGRA, at night it keeps me awake. In other words, I stay awake for most of the night and get not sleep at all. This is the reason why I don’t recommend ALLEGRA because it will keep awake and get no sleep at all. I need to find other way to fight my allergies."

For Allergic Rhinitis "Allegra 24 hour helps my hay fever symptoms. But, this medication dries out my lung tissue to much and makes me cough. I have been off Allegra for a week and I am still coughing and have LOTS of non infectious mucus coming out of my lungs. My lungs hurt from coughing. I am 62 year old female with mild asthma."

For Allergic Rhinitis "After about 4 years of terrible hay fever, lasting from about September to May, I have finally found my cure! I have tried countless allergy medications, including Zyrtec. None of them seemed to work until my doctor finally told me to try Allegra 180mg. I have not experienced any side effects, except I did have a sore throat about a week after starting Allegra. I definitely recommend this product."

For Allergic Rhinitis "Don’t buy the worthless medicine at all it doesn’t work. I wasn’t having a good day, all day I couldn’t breathe and it was bugging me. So I bought Allegra. And I could tell you, it didn’t work at all. It was like I never even took medicine. It didn’t help or nothing I couldn’t breathe all night and it was frustrating. Don’t buy!"

For Allergic Rhinitis "God bless the one who invented Allegra! I had been snoring all the time even during summer and I felt my nose was wet and tickled me all the time. I tried everything to stop that instantly snoring problem when I took only one pill it just stopped. I didn't snore or sniff a whole day, and before that, a day without sniffing would be a miracle. I didn't even have to wait one hour it just work direct!"

For Allergic Rhinitis "I have had bad allergies my entire life and was given many different medicines to try. This is the first medicine that actually worked for me. I took one 24hr dose yesterday at 4pm and today at 10am my nose is still clear. The only problem I had was that my blood pressure spiked up to 146/93 from a normal range of 120/70. During that time I had a terrible headache and felt extremely dizzy. I went to bed and woke up to recheck my blood pressure. It was still elevated at 127/86 and I still have a slight headache, but I can breathe."

For Urticaria "From past 1 yr I'm having chronic urticaria. If my diet is clean no hives occurs, it's due to food that I eat. After months of steroids and h1 & H2 antihistamines I have recovered almost 70% now from past 3 days I didn't took any medicine, as I ate some oily food n chicken outside my hives have increased so now I'm taking Allegra 120 mg (half)tablet after reading all the above comments. Next review will be soon"

For Allergic Rhinitis "I have been taking Allegra for over a decade when it was only available on prescription. Over the years my insurance company forced me to try all the allergy medicines that went OTC in hopes that they wouldn't have to continue to pay for Allegra by prescription. However, nothing ever worked for me like Allegra. The other drugs caused side effects that I could not tolerate. I have no side-effects from Allegra what-so-ever. It has been a miracle medication for me and my year-round allergies."

For Allergic Rhinitis "I take allergy preparations year round, Claritin in fall and winter, and Allegra spring and summer. Both claim to be effective immediately, (within hours) however, my experience is that it takes a week for them to work, so, for a week in spring, and a week in the fall, I take both, otherwise I am miserable with runny nose itchy eyes, sore throat, etc. Both claim to be non drowsy, but for me this is not the case, so I take them at night. I give allegra a middle of the road 5 as a rating, because it's better than nothing!"

For Allergic Rhinitis "I have had a lot of trouble finding a newer antihistamine that works well for me. I have tried all the 24 hour ones and Allegra seemed to be the right fit, but I had to stop taking it when I noticed yucky side effects. I realized that it was causing GI issues such as abdominal cramps, nausea, and diarrhea. I was also getting dizzy spells out of the blue. When I don't take the Allegra, I'm fine. It's a catch-22 because it does seem to help with my post-nasal drip, but it's not worth having GI issues over."

For Allergic Rhinitis "I've never encountered hay fever allergies prior to this spring, so as soon as it all began, I decided to do some research. Allegra looked like my best bet because it claimed that drowsiness was not a side effect, and I was told it would work quickly! I decided on the 24-hr. I have yet to notice a difference and have not been sleeping very well! "

For Allergic Rhinitis "Recently I have been having VERY bad allergies and went to the doctor. She said that I should try Allegra (not Allegra-D) and that it is available over the counter. I went to the store but could not find any adult 12 hour Allegra. This disappointed me because I knew the 24 hour pills usually don't work. I went ahead and bought the smallest package of pills I could get (5) of the 180mg dosage. I took one and it cleared up my symptoms and made me feel better but that night I woke up after about 4 hours of sleep and could not get back to sleep. I didn't take one the next day as I wanted to get a good nights rest. Yesterday I took another and the same thing happened again. I just want to SLEEP!"

For Allergic Rhinitis "I normally use Claritin but ran out. I took 1 Allegra 12 hour and it was completely worthless like I took nothing. I had to wait and suffer for 12 hours until I could buy some new Claritin and that worked."

For Allergic Rhinitis "Day two... I have taken 2 gel caps and it has not helped. Itchy roof of mouth. Unable to breathe through my nose, it is completely stopped up. Symptoms are worse than yesterday. Eyes are red, itchy and teary. I a cannot sleep. I do not recommend."

For Allergic Rhinitis "I was prescribed Allegra after years of using Sudafed over the counter believing that my sinuses were the problem. My GP and I finally managed to figure out that the problem was allergic rhinitis. I take 180mg on a daily basis and since I've been taking I don't suffer with too much blockage and congestion however I have gained weight since taking this daily. I am doing a trial run of going without Allegra and also Cerazette to see whether bloating goes down. It's brilliant for my allergies without a doubt, the pro's outweigh the cons however I cannot continue gaining weight. Within 6 months of taking these alongside Cerazette daily I have gained 1st. I am trying to find a new alternative although this has worked brilliantly."

For Allergic Rhinitis "I took Allegra 24 hours recently for the past two days. It works fast and relieves every symptom, but has only lasted for me for up to 8 hours. I then end up having to supplement with Benadryl but it makes me drowsy."
