Desloratadine, sold under the brand name Clarinex among others, is a medication used to treat allergies such as hay fever and hives. Onset occurs within an hour and lasts for up to 24 hours. It is taken by mouth.

Common side effects include nausea, tiredness, dry mouth, and headache. A lower dose is recommended in those with kidney or liver problems. While there is no clear evidence of harm during pregnancy, such use is generally not recommended. It is a second generation antihistamine. It is an active metabolite of loratadine.

Desloratadine was patented in 1984 and came into medical use in 2001. In the United Kingdom it is avaliable as a generic medication and costs the NHS about 1.5 pounds per month. In the United States this amount costs about 17 USD. It is also available with pseudoephedrine.
