Uses

What is Allerta® used for?

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.

Allergic rhinitis
- Sneezing

Skin symptoms of allergy such as itch and rash
