Claritin (loratadine) for Allergic Rhinitis "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 Nondrowsy 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."

Claritin (loratadine) for Allergic Rhinitis "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/head aches. I also got joint pain in my knees. I looked up these two side effects and sure enough a good percent of female patients age 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."

Claritin (loratadine) for Allergic Rhinitis "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."

Claritin (loratadine) "I have taken Claritin for two days. I seem to have had a rare hypersensitivity type allergic reaction to Claritin. I got widespread body pain. Pain in my shoulders, arms, legs and hands. It was hard for me to walk even. Online it says hypersensitivity affects .01% of people. Lucky me. Claritin remains in effect for 24hrs. Glad that Claritin gets completely out of your system in 36 to 48hrs. Will not be taking this again."

Claritin (loratadine) for Allergic Rhinitis "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!"

Claritin (loratadine) for Allergic Rhinitis "First symptoms were congestion in my nose and vertigo from fluid in my ears. After a visit to an ENT 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 feel like this before. Any reading the comments on here, I stopped all medication and feel better less than 48 hours after. Not 100% but headed in right direction. Anyone else feel this way?"

Claritin (loratadine) for Allergic Rhinitis "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 clairtan can offer so I tried it. Within and hour or so my post nasal drip was a whole lot better and my cough along with it now I am on day 5 of taking clairtan...I feel like I could go out dancing I am sure it can only get better from here ...GOSH why didn't I try clairtan years ago ...."

Claritin (loratadine) for Allergic Rhinitis "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."

Claritin (loratadine) for Allergic Rhinitis "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 it 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 till 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."

Claritin (loratadine) for Allergic Rhinitis "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."

For Allergic Rhinitis "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 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 cant take a decongestant due to the ingredient causing worse fatigue."

Claritin (loratadine) for Allergic Rhinitis "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 can finally stand up without feeling dizzy."

Children's Claritin Allergy (loratadine) for Allergic Rhinitis "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. "

For Allergic Rhinitis "After a trip to the Urgent Care again, and a diagnosis of severe sinus infection, pressure in head, fluid around ear drum-almost an infection, excessive post nasal drip, and slightly asthmatic due to allergies! This is a repeat scenario and I have tried ceterizine, 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 Claritan 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 Claratin/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 10mg but plan to go to 5mg child dosage. :0)"

For Urticaria "Took 1 loratadine in the evening as I was recommended by my doctor for hives. Struggled to sleep and later started shaking, rapid heartbeat, confusion. I have never had side effects like this due to any allergy pills previously. This is the worst and scariest thing I have experienced. This drug is not worth taking"

For Allergies "Do not take this if you suffer anxiety. I remembered taking this 2 years ago and I had a panic attack so I didn’t take anymore. Forgot which one it was and I picked up a pack this week. I was 7 months anxiety/panic attack free until I took this the second time. 2 hours after swallowing I was dizzy, confused, irritable, severely anxious, shaking, sweating, racing thoughts that wouldn’t stop. It completely stopped my nose and eyes running and itching but I would take that any day over how I felt on this. Never again for me."

Claritin (loratadine) for Allergic Rhinitis "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."

Claritin (loratadine) for Allergic Rhinitis "This stuff did very little for my allergies. It made me feel tired and spaced out and gave me minor heart palpitations. Benadryl works much better but has some dangers if taken long term. Nasacort has few side effects for me but only limited help. Some homeopathic nasal sprays work better than most OTC stuff."

Claritin (loratadine) for Allergic Rhinitis "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."

Claritin (loratadine) "I ran out of zyrtec and did not have a lot of money so I opted for 2 one packs of claritin non drowsy 24 hr, I have severe anxiety and moderate depression, that I’ve been regulating on my own for the past 3 years. So the first night I took it and the next day I could barely get out of bed without feeling nauseous and dizzy. I also noticed that my anxiety in the car was heightened and I almost had to pull over because I felt so sick. I didn’t take the pill the next day and within the next day my anxiety went away. This morning my allergies were so bad I took the 2nd pill knowing what could happen and I’m dealing with the worst anxiety I think I’ve ever had, I couldn't get into the car without feeling like I was going to pass out. So ultimately I will not be taking claritin anymore because like others have reviewed also that it affected them mentally and caused anxiety and a weird head feeling, also did nothing for my allergies compared to my zyrtec."
