What is Loratadine?

What Is Loratadine Used For?

As an antihistamine medicine, loratadine is useful in treating symptoms of allergies and hay fever. It helps to reduce itching and swelling and prevent runny nose, watery eyes, and sneezing. Loratadine helps to fortify the immune system, allowing it to better protect against allergens such as pollen and dust. 

How Does Loratadine Work?

Loratadine works by blocking the action of histamine, a substance in the body that contributes to allergic reactions. Histamine is a chemical that is released by white blood cells into the bloodstream when the immune system is threatened by a potential allergen. When released, histamine often causes an allergic reaction. Allergic reactions can be triggered by many substances including pollen, mold, and certain foods.
