Effectiveness
How Clarinex Affects PatientsDesloratadine is an anti-allergy medication that stops the effects of histamine, a chemical that causes many symptoms associated with allergies like tissue swelling. It works by blocking one type of receptor that histamine attaches to on cells, which prevents cells from being activated. Desloratadine does not enter the brain, so it does not make people feel sleepy, unlike some other antihistamines.
How Clarinex works in the bodyDesloratadine is an antihistamine that works by blocking histamine from binding to certain receptors in the body. This action stops the negative symptoms caused by histamine, like congestion and watery eyes.

Clarinex Reviews: What are patients saying about Clarinex?
5Patient Review
5/18/2009 I'm really glad we found this medication, it's been effective in preventing my daughter's coughing spells. The only downside is that it dries her nose out, but we've just been giving it to her at bedtime and so far it hasn't been a problem.
5Patient Review
6/4/2009 I'm so grateful for this medication! I had to take two days off of work because my allergies were so bad, but this cleared me up within 5 minutes.
5Patient Review
4/30/2009 Unfortunately, this medication had the opposite of the intended effect on me. My nose ran constantly after taking it, rather than stopping a runny nose from a cold. I won't be taking any more of these pills.
5Patient Review
2/5/2014 Clarinex has been a life-saver for me during allergy season. It's the only medication that has worked for me, and I've tried several other brands over the years. If you're struggling with pollen allergies, I highly recommend giving Clarinex a try.
5Patient Review
6/29/2009 We tried this for ten days on a sample we got from the pediatric allergist. We had ten uninerrupted nights' sleep and good reports at school. When we ran out of Clarinex we went to Zyrtec as recommended and the difference was like night and day, Clarinex works, period.

It is effective in relieving congestion and other allergy symptoms. Zyrtec D (cetirizine / pseudoephedrine) is another option that relieves allergies and congestion without causing drowsiness."
