Allerta® (loratadine) is a type of drug known as an antihistamine. Allerta® works by binding to histamine H-1 receptors on various cells throughout the body, including white blood cells. By blocking histamine, it prevents symptoms such as sneezing, itchiness, redness, inflammation, and runny nose.
Loratadine is a second-generation antihistamine so it is less sedating than first-generation antihistamines, such as diphenhydramine.
Allerta® is used to treat the following:
