For Nasal Congestion "I started this medication 5 days ago due to post-nasal drip, phlegm coughs, runny nose... My doctor told me to take 24 hours. As far as side effects: I experienced slight insomnia... a little longer to fall asleep, my head is not quite clear, I feel a little foggy when I need to concentrate, and a little fatigue. No major side effects. The medication has helped but has not completely 'cured' me. So overall, it's worked, but it's not a miracle."

For Nasal Congestion "I have bad spring allergies which last me about 2 months. I was sick and tired of blowing my nose millions of times a day and couldn't breathe through my nose. My classmate suggested that I take Claritin-D 24 hours. This pill works great, but there is a huge side effect which I hate. Pros - cleared my nasal passage, stopped sneezing, stopped itchy eyes, stopped running nose. Cons - dry mouth, weakness, insomnia, dizziness, feeling high, and pain in my thigh and leg. But otherwise, this works great, such a lifesaver."

For Nasal Congestion "Big mistake taking my first Claritin D 24 at 7 PM for sinus pressure from using a nasal decongestant the day before and getting a rebound effect of clogged breathing passages. Didn't sleep a wink all night! My nasal passages are wide open though, so it works. However, insomnia is a real pain. It's 6 AM and I feel like it should be 1 AM bedtime. I'll be struggling through the day today. Restless in Philly."

For Allergic Rhinitis "Works great most of the time. The problem is the price is going up and up. The other problem is the restriction on the amount that can be purchased at one time. I take one every day, but I can only buy 15 at a time and only 30 in a month. It's hard to believe that the sale of the medicine has to be controlled. On the last day of the month, I have to wait until the next day to buy the med-so stupid. Especially when traveling, and I can't purchase some in advance. It should be prescription again so I can receive 30 at one time."

For Nasal Congestion "I've been denied the last 2 months on the purchase of Claritin D. I'm suffering with congestion, itchy eyes, runny nose. Regular Claritin doesn't work. Only Claritin D. But when you need it, you can't buy it."

For Allergic Rhinitis "I will say it worked well for my stuffy and runny nose from AR… but it’s kind of impossible to sleep when I’m taking this, even if I take it first thing in the morning. I also get super nauseous and shaky from it, and almost felt ready to pass out a few times. The dizziness is a bit too scary for me, lol. I’d say stick to the 12-hour version or just skip the pseudoephedrine if you feel like this too."

For Allergic Rhinitis "The worst medicine ever tried, shaking, anxiety, heart palpitations, insomnia. Regular Claritin is much better, the pseudoephedrine is a dangerous drug."

For Nasal Congestion "Benadryl is WAYYYYY better. Claritin does almost nothing for my allergies. Would strongly suggest not wasting your money on this product."

For Allergic Rhinitis "I have been taking this for my allergies for a few years now and LOVE it. The single daily dosage is great - I have NO 'downtime' between doses. However, every year the supply runs out."
