"As an industrial insulation specialist, I have spent the last 6 years of my life suffering from chronic sinusitis, constant fatigue, pressure in sinuses and behind my eyes, ear infections, sinus infections, colds in all seasons. After extensive doctor visits and lots and lots of medical bills, I finally ran into an amazing doctor in the E.R. My sinuses had taken me on a turn for the worst, constant blurry vision, headaches, sinus pressure and pain, pain in ears, dry throat, disorientation, pain at the base of my skull, and constant fatigue. This doctor turned me on to Claritin-D. I have felt like a brand new person ever since. I am loving life again and living to the fullest. Thank you so much for changing my life, Claritin-D."

"Claritin-D did help my nasal congestion, but the side effects I experienced just weren't worth it. It made me nervous, jittery, and caused extreme insomnia. I did notice that my nasal congestion improved, but I can't tolerate the side effects."

"Definitely cleared up my nasal congestion, but totally not worth it due to the side effects. I took it around 9 this morning. It is now past midnight, and I'm still feeling it. All day I have been jittery, anxious, irritable, and had terrible dry mouth. I'm exhausted right now, but I can't sleep. Wish I read these reviews before taking!!!"

"I have used Claritin-D 24 for 5 years. I used to get sinusitis all the time. It was so bad, I usually missed 2-3 weeks of work per year. I was tested for allergies, but was allergic to nothing they tested for. I used to take it only seasonally, but as soon as I stopped, I would get sick again. Now I take it every day and am very nervous if the pharmacy runs out. I do experience a few side effects, but have learned to manage them. For instance, I do not take it if I can't take it before 10 a.m., otherwise, it causes insomnia. I also have dry mouth, but have increased my water intake to 8 glasses per day (good for me). I have experienced joint pain in the last few years, but determined it was due to plantar fasciitis. It's changed my life."

"I literally have tried every home remedy and allergy medicine out there. Until I tried Walgreens generic Claritin-D for nasal congestion and allergies, way cheaper, and you get the same results. I had nasal congestion, fever/headaches, itchy throat, and earaches. After one dose, I felt like a new person. I truly recommend this product to anyone suffering from the same symptoms I had... :-)"

"I use Claritin-D for my seasonal allergies. I started again this May. After taking it for a week, I have noticed my heartbeats faster than normal (100s now from 60s) and my blood pressure went up from 110s systolic and 70s diastolic to 140s/90s with headaches. So, I was thinking what's going on with me. I started salad and no salt diet for a week now (lost 5 pounds and feel good), increased my cardio to 45-60 mins 4 times a week, cut sodium intake, but my blood pressure stays high. I started reading about Claritin-D, and BOOM. This is what is causing my blood pressure to rise up! Today, I stopped using it. Sticking to the plain Zyrtec."

"Definitely helps with nasal allergy symptoms, but the side effects are not worth it. Thankful to Googling & finding this site because I thought I'd have to take myself to the ER. Jittery, rapid heartbeat, anxiety either from Claritin or from worrying about the jittery, uneasy feelings. Thanks to everyone who has shared here. I think I'll just suffer my allergy symptoms naturally."

"During the winter, I have a lot of trouble breathing because of the dry heaters. Blowing my nose is often not an option. Claritin-D clears up the passages and allows me to breathe freely. I feel more alert and experience no side effects. I use the 12-hour pills no more than once a day."

"This medicine is great. I was diagnosed with sinusitis and could not breathe at all through my nose. After taking Claritin D, what a difference. I could breathe again and finally could get a good night's sleep. It does give me dry mouth, so I just drink more water."

"Have had lifelong issues of allergies and sinus congestion/infections. This is the first thing that has worked. Only use the 12 hr formula taken early in the morning. 24 hr didn't allow me to sleep well. Noticed a higher heart rate/jittery feelings for about the first two weeks, then my body got used to it. This med has improved my health and allowed me to stop taking multiple meds that could not provide the relief that taking one Claritin-D has."

"Clears up allergies like a charm, but side effects are no joke. Jittery, trouble sleeping, massive anxiety, I couldn't sit still, went on a cleaning binge for hours on end, though lol. Woke up the next day drained, still feeling some side effects. Scary drug."

"I took Claritin D this morning because of severe nasal congestion, it was relieved after a few hours, but the side effects are not good. I can't sleep. I am so tired and want to rest, but I am still wide awake until 1 a.m. How I wish I had read the reviews first before taking it... so no more Claritin D... I will go back to Allegra."

"Doctors gave this medicine to me thinking I had an allergy. I thought it was a cold. I did not have any runny nose, itchy eyes, or anything as mentioned on the label of the box. I took Claritin-D 12 hrs when I felt I got congestion in the nasal passage and felt like mucus was passing through the passage between my nose and throat all the time and got different side effects all the time. This time I had severe side effects like starting to feel feverish, my heart was pounding faster, felt extremely weak; then I read about the side effects on this website."

"I'm 18. I have a severe sore throat to the point of my tonsils becoming inflamed, and to add to that, my ears started to hurt! So, I took Claritin-D, and I understand this is a decongestant, so my ears were better, but my throat was drier (that's the side effect I found out later), and I'm up all night! Was in bed from 10 PM to 4 AM, and now I have a 7 o'clock flight. Great, never again!!!"

"This product worked well for my post-nasal drip. But I felt extreme pressure in my sinuses, especially in my ears. I had terrible dry mouth, which created a horrible sore throat. Not to mention I took it at night, and I got terrible insomnia. I felt jittery and just absolutely horrible. I wish I had read these reviews before taking it! No more Claritin-D for me. Stick with the regular Claritin."

"Claritin D 24 hour works well for sinus issues. However, the side effects that I experienced supersede the effectiveness of the drug: decreased urinary stream, cloudy urine, straining to push out urine from the bladder, insomnia, headache, increased heart rate. All symptoms lasted approx 24 hours. Inconvenient to purchase; have to show driver's license, as I found out its main ingredient is used to make crystal meth."

"Super effective! I have been using it as needed for about three years now; however, tonight is the first night that it has ever kept me awake. I mean literally wide awake, cleaning my house at 3 AM awake. Definitely worth it and clears up congestion instantly, but taking it in the late afternoon was a huge mistake!"

"I started having allergies about two years ago during the spring, and I never took any medications for it. I have two cats, and during this time of year, my eyes get red and 'poofy', the back of my throat itches badly, I have phlegm when I cough, and my nose is always congested, itchy, and runs at the same time. When I sneeze, I have to blow my nose about ten times to get all the mucus out. I started taking Claritin about 3 weeks ago, and immediately, I noticed no red and itchy dry eyes, and my throat is relaxed, but I still had my crazy nasal congestion, itchy, and runny nose. About a week ago, I bought Claritin-D 24-hour dose, and I am amazed. I am able to breathe again - through my nose. I highly recommend this medicine."

"Claritin-D is amazing. It allows me to breathe and work/drive/live at the same time. I actually feel better than normal when I take it. I wake more refreshed and seem to focus better. No negative side effects for me."

"I took this at 10:00 a.m., and it is now noon the next day, and I haven't slept at all. Will never take again, wish I had found this site before taking it. And the pharmacist said it could make me drowsy! Ha!!!"

"I have taken regular Claritin for years with no ill effects. My wife went to the pharmacy to pick up for me, and they gave her Claritin D 24 hour. I asked her what it was, as the package looked different, she explained that the pharmacy told her it’s a new formula. I took it for 6 days and had terrible insomnia, fast heartbeat, and anxiety all day. I did not realize that the medication contained an extra ingredient, it had loratadine plus pseudoephedrine. It was the pseudoephedrine that was the cause of this, and I had just thought it was regular Claritin. This medication should come with very clear warnings, as it is actually dangerous."

"I have post-nasal drip and swelling from mucus in my throat. I’ve had surgery, which was only about 50% effective. I started taking Claritin-D about 3 years ago, and it helped open me up but made me too jittery and made my heart race. I needed the pseudoephedrine to open me up. I discovered if I cut it in half, it doesn’t affect me as badly, and it still works to open me up. I have to take it by 10 AM so it doesn’t affect my sleep later. No other effects from this medicine."

"Incredible med!!! Have tried everything for allergic nasal congestion for years. I take the Claritin 12-hour in the morning, which keeps my head clear for 24 hours. The 12-hour works for 24 hours for me. Wake up unplugged!! I also use a Navage sinus rinse to clean my sinuses 2 times a day."

"I took this pill one time, and it's horrible. I couldn't eat, and nervousness is an understatement. The bottom line is this: I now realize why you can only purchase it from behind the counter of a pharmacy. I have never done meth, but this is probably a pretty close first. You all know that this is the main ingredient used to make meth, right? Horrible. I'll stick with the congestion."

"Claritin-D is very effective for getting rid of congestion. Also very effective at getting rid of any chance for a good night's sleep. I was taking it for about a week and got about 1 hour of sleep each night before I figured out what was causing my insomnia. Back to regular Claritin for me. I would much rather suffer worse symptoms than not sleep at all."
