For Allergic Rhinitis "On its effectiveness, I rate it a 10 because it will completely eradicate all your allergy symptoms. However, the undesirable side effects lower the rating to a 3. It will keep you up all night long. It also made me jittery and nervous, as if I'd drank a dozen cups of coffee."

For Nasal Congestion "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."

For Nasal Congestion "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!!!"

For Allergic Rhinitis "Amazing at clearing up symptoms. However, I took this at around 10 a.m. with a coffee and was up all night. It’s 24 hours later, and I’m still wide awake and jittery, even after popping a Valium around 2 a.m. I already have sleep/anxiety issues, so no more Claritin-D for me. The nice thing is my house is spotless after going into some kind of manic cleaning mode while hopped up on Claritin-D."

For Nasal Congestion "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."

For Nasal Congestion "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."

For Nasal Congestion "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."

For Allergic Rhinitis "I took the Claritin-D pill at 3 PM, and right now it’s 5:29 AM. I cannot fall asleep! Feeling anxious, even trying to force my sleep, I can’t. Took a sleeping aid and nothing. I feel like my breathing cuts off. Also, I took the 24-hour one. BAD IDEA! I read people here took the 12-hour and can’t sleep. I guess I’ll be like this for 3 days. If you have allergies or congestion, just buy the regular ones, not the D! And use saline spray for the nose."

For Allergic Rhinitis "Definitely clears up the congestion and allergy symptoms, which is why I'm giving it a 2. The side effects, however, are terrible. It makes me so jittery and unable to sleep, it's not worth taking. It took me a few times to make the connection, but now I know it's the Claritin-D."

For Nasal Congestion "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."

For Allergic Rhinitis "Awful. Immediately after I took it, I felt nauseous, an extreme sadness, dizzy, and anxious. A few hours later, my mood went back up, but then I became jittery and had insomnia. Didn’t get a single hour of sleep. I do not recommend."

For Allergic Rhinitis "I took Claritin-D about five PM. At 11 PM, I went to bed, but my heart was racing, I was jittery, and absolutely wide awake. My mouth was so dry it was uncomfortable. Watched the sunrise. Was still jittery, irritable, and anxious throughout the entire next day. It was about nine PM (so over 24 hours later) that I started feeling back to normal. Absolutely horrible. If I hadn’t read the other comments on this site, I would have probably gone to the ER. Will never take pseudoephedrine again."

For Nasal Congestion "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."

For Nasal Congestion "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."

For Allergic Rhinitis "Worked great for my sinus and allergies. Had head and throat issues so bad, so the pharmacist recommended Claritin-D 24 hr. I made the mistake of taking it at noon, and it is now 6 a.m. and I'm still awake. Wired and jittery, and my anxiety is raging. I can't sit still... not worth the lack of sleep."

For Nasal Congestion "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."

For Allergic Rhinitis "Like many have said, it definitely cleared up the horrible sinus pressure I was having, but the trade-off was spending the entire day feeling 10x more miserable because of the crazy side effects. It made me feel drowsy, woozy, and extremely nauseous, while also feeling anxious, unable to concentrate, and unable to sleep all at the same time. I also had a sensation of pressure on my chest and felt like my heart was racing. Never again."
