About loratadine

Type of medicineAntihistamine (non-drowsy)
Used forAllergies including hayfever and allergic skin rashes

Exposure to substances such as pollen, animal fur, house dust or an insect bite can cause the body to produce a chemical called histamine. The release of histamine causes allergic symptoms which can include skin rashes, sneezing, watery eyes, runny nose and itching. Loratadine stops the effects of histamine and helps to relieve these symptoms.
