Loratadine

Loratadine (also known as Claritin) is a type of drug called an antihistamine. It is used to treat hay fever, urticaria, skin allergies, some food allergies, eczema, and insect bites or stings.

Loratadine was discovered in 1981 and first sold in 1993. It comes in ordinary tablets, melt-in-the-mouth tablets, and liquid. It is usually taken once a day.

Loratadine is a non-drowsy antihistamine. Compared to some other antihistamines, loratadine is much less likely to make people feel sleepy. 

It is closely related to tricyclic antidepressants and distantly related to quetiapine.
