Loratadine "It was effective for my allergies, however, it caused many side effects that are listed nowhere! Depression, anxiety, confusion, and sleepiness that was so pronounced I had to pull over while driving. This was the Non-drowsy formula. There are 11 other people who had similar reactions in the support in drugs.com group, under the drug name. I'll deal with my allergies rather than end up in the psych ward."

Loratadine "First symptoms were congestion in my nose and vertigo from fluid in my ears. After a visit to an ENT, I was told to take Claritin and Flonase along with Azelastine. Worked wonders for my congestion but started to feel really foggy in my head. Back to the ENT and had a hard time describing my symptoms other than being 'off.' This brought on anxiety, did not want to drive, or leave the house. Never felt like this before. After reading the comments on here, I stopped all medication and felt better less than 48 hours after. Not 100% but headed in the right direction. Anyone else feel this way?"

Loratadine "I was prescribed Claritin by my ENT. I was told to take it every morning, which I did, but after a few hours of taking it, I would get the worst neck pain/headaches. I also got joint pain in my knees. I looked up these two side effects and sure enough a good percent of female patients aged 49+ reported these side effects. Seems more common in females. It did nothing whatsoever for my severe allergies and my Otis externa. I couldn't take the pain from this drug and stopped. Within 24 hours, the painful aches went away."

Loratadine "Read some of the reviews, says it causes confusion, anxiety, depression. I took it for 2 days. 1st day I didn’t feel anything except my ears started ringing really bad. 2nd day I took it, it caused the worst confusion of my life. Going on the day after and I still feel like rubbish. Don’t take this drug."

Loratadine "I have had postnasal drip and chronic cough, especially in the winter for at least 10 years. Scratchy throat, itchy ears, sore throat, and burns at times, facial pain, sneezing. I just got over what I thought was a sinus infection. I was still feeling bad, so I was doing some reading, and I read what Claritin can offer, so I tried it. Within an hour or so, my postnasal drip was a whole lot better, and my cough along with it. Now I am on day 5 of taking Claritin. I feel like I could go out dancing. I am sure it can only get better from here. Gosh, why didn't I try Claritin years ago?"

Loratadine "I've been on this product for a few years. Works great. Makes me super thirsty but keeps my sinuses clear. My eyes aren't red and itchy. Even my skin has cleared up! My son was put on this, and when I saw he was doing better, I joined him on it. No problems with sleep or tummy aches!"

Loratadine "The first day it was effective, but I started to feel tired and sad. I also suffered from lack of sleep and felt thirsty all the time, even though I drank lots of water. I was not able to do number 2 :-) for 3 days, and I had stomach aches. I stopped taking this drug immediately."

Loratadine "I have chronic allergies (undiagnosed). I suffer from dry, red, stinging eyes and a nose that gets stuffy even with turbinate reduction surgery, as well as general fatigue and low energy. Claritin helped me feel functional again, and I can look people in the eye when I talk to them. Nose is a lot more clear. It is VERY important to take it for a week before it provides full relief. This did not start working for me until day 4, and now I feel great, perhaps the best ever. I am giving it an 8 because it causes me dry mouth, and my sleep is not the greatest. The point of this review is not to fully trust all the negative reviews. Try it for yourself every day for one, maybe even 2 weeks, and see how it affects you. Best of luck."

Loratadine "Claritin is very effective on my allergy symptoms, but it also makes me drowsy. However, I've had problems getting a good night's sleep in the past, and the usual OTC sleep aids like melatonin and Advil PM don't always work for me. With 'non-drowsy' Claritin, I haven't slept this well in ages! Need to ask my MD or a specialist if Claritin induces good quality, healthy sleep and whether I can keep taking it as a sleep aid."

Loratadine "Took one 24-hour Claritin on Sunday. Within hours, my itchy eyes and runny/stuffy nose had cleared. Took a second Claritin on Monday. Poor sleep that night. Tuesday morning, getting out of bed, I experienced a terrible backache and the beginnings of a headache that Tylenol didn't touch. Backache lasted all day. Stopped Claritin before my third dose. Today is Wednesday, and I'm feeling zombie-like, fatigued, with lingering back pain. Much as I had hoped this might be my miracle pill, it's not. I'm a 70+ year-old lady in good health who will not be taking this again."

Loratadine "This medicine, Claritin, I swear on God, it’s the best. I've tried other medicine like Zyrtec and over-the-counter ones, but this is the only thing that works and it kicks my allergies in instantly, like 20 min tops, and lasts for days."

Loratadine "This is the 2nd time in a month that I have suffered from dizziness and fatigue after taking Claritin. My blood pressure has dropped to 96/58, which is low even for me. I have always had lower than normal blood pressure. I last took Claritin on Thursday morning, and this is Monday, and I can finally stand up without feeling dizzy."

"After a trip to the urgent care again and a diagnosis of severe sinus infection, pressure in head, fluid around eardrum-almost an infection, excessive post-nasal drip, and slightly asthmatic due to allergies! This is a repeat scenario, and I have tried cetirizine, but it does not stop my severe post-nasal drip at all. So the doctor (who also has allergies and a wife with severe allergies) told me to take Claritin during the day and also prescribed cephalexin, steroids, and an inhaler. Well, after praying and spending another 2 hours spitting due to post-nasal drip, I took the Claritin/Loratadine. Wow, it stopped my post-nasal drip in only 20-30 minutes! *** My reactions were sudden drowsiness even though it says non-drowsy, and before that, a few heart palpitations. However, it did work, and nothing else has stopped my symptoms! I have indoor/outdoor allergies, numerous food and medicine sensitivities, and allergies, and so on. * Tried the 10 mg but plan to go to 5 mg child dosage. :0)"

Loratadine "Honestly, I am very sensitive to medications, so I should have felt some sort of relief, and I felt nothing but side effects. Dizziness, fog brain, and overall, it made my head feel strange. I will be discontinuing this medicine and trying something else."

"I purchased Claritin NON-DROWSY (yeah right) this morning. I took one at 10 am, and within an hour, my symptoms all stopped. I felt exhausted and spaced out, and by 4 pm, I started to feel like I was on speed and wired. I felt like I was in slow motion, saying, 'What the heck is going on with this?' It’s nearly midnight as I’m typing this, and I feel tired but wired. I can’t wait till morning, being it’s a 24-hour dose for this to leave my body, but it did stop my coughing, all day wheezing, sniffling, and sneezing, but these side effects are not worth it. Anyone have any recommendations for another allergy med, as I can’t take a decongestant due to the ingredient causing worse fatigue."

Loratadine "My five-year-old son took Claritin chewables for approximately two weeks and had a sudden onset of facial tics (eye blinking). His doctor attributed it to the Claritin and said it was a known side effect, especially with family history of tics."

Loratadine "I have had a stuffy nose for 4 days, and I have tried everything. I remembered that I had Claritin, so I took one, and it helped me so much. My nose became normal, and I feel so much better. Thank you, Claritin."

"33 years old male living in central Texas. Loratadine is extremely effective in eliminating hay fever and allergic symptoms, feels clear as can be, however, the side effects are also prominent. Currently taking 10 mg per day, completely eliminated hay fever, but it's giving me constipation and very slow and difficult bowel movements. Dry mouth and irritable trachea are also noticeable, but I can live with those. Planning on reducing the dosage to 5 mg or 2.5 mg and see if the side effects persist."

Loratadine "I was experiencing night sweats and racing heart. I figured the only thing I had done differently was take Claritin. I went off and the night episodes disappeared. I tried it again. Wow. Night sweats, pounding heart, muscle pain. I will never be taking this again. Strange, as I took this often when younger with no problems. This is the Walmart generic version."

Loratadine "I took Claritin for congestion due to allergies. Day 1, I felt a bit tired after taking it, but the congestion began to clear. Day 2, I felt fine for a few hours with the exception of dry mouth, all of a sudden, I became severely dizzy and felt like I was going to fall out of my chair. Checked all my vitals: BP, oxygen, sugar, etc., and they are perfect. The only new medicine I took was Claritin. I am lying on my back right now, writing this review while I am recovering from the effects."

Loratadine "It did help with symptoms, but it caused depression for me. Took it for three days, then realized that I had depression. Google Claritin and depression, and the second listing that comes up is a discussion on this website about Claritin from users saying it caused depression for them."

Loratadine "24-hour pill, and I still have 14 hours to go. Fluttering of the heart has made this drug very uninviting. Head is more stuffed now than when I started it. Not a very comfortable feeling. Headache, stuffy nose, jitters, and some stomach discomfort. Use caution."

"First of all, I'm not and never have been a smoker. Have COPD due to chronic bronchitis, I developed asthma after 40. I've been taking this product for five years, and the illness due to weather has decreased dramatically. I had previously suffered from pneumonia due to worsening bronchitis at least twice a year. I average once every three years now, it is due to consistently taking this year-round."

Loratadine "Absolutely no relief whatsoever from a severe allergy condition I had for one day a few weeks ago. Wrote to Bayer, they responded the next day with promises of a refund, but nothing after initial first contact. Do not waste your money on this product, try something else."
