In brief: Blocking histamine
Claritin (loratadine) is one of a group of drugs called antihistamines.
These block the natural chemical histamine from binding to its receptors which then trigger your body into having an allergic reaction. So, basically, you have histamine in your system which increases when you are exposed to something you are allergic to. Claritin (loratadine) and others block that histamine from hurting you.
