How Does Fexofenadine Work? 

As an antihistamine medication, fexofenadine works by preventing the effects of histamine. It works on the peripheral histamine reactors which are located outside the brain and spinal cord.

Histamine is a chemical released by cells in response to an allergen. It is responsible for many of the symptoms of an allergic reaction, such as swelling, sneezing, and itching.

Fexofenadine works to prevent the effects of histamine by binding to histamine receptors and prevents histamine from having an effect on those receptors.
