What is Fexofenadine?
Fexofenadine is a highly effective antihistamine medicine used to treat seasonal allergic rhinitis, commonly known as hay fever. Sufferers of hay fever often exhibit symptoms including a runny nose, sneezing and red, itchy, and watering eyes. Fexofenadine works by blocking histamine receptors in the spinal cord to prevent or reduce the symptoms caused by the release of histamines in response to an allergic reaction. Fexofenadine is classed as a non-drowsy antihistamine, it offers an effective alternative if non-prescription hay fever treatments have not been previously successful or symptoms are particularly chronic and persistent.
How does Fexofenadine work?
Fexofenadine contains fexofenadine hydrochloride which is a non-drowsy antihistamine. Histamines act as neurotransmitters and are released in the inflammatory response during an allergic reaction, they cause a chain reaction resulting in allergy symptoms. Fexofenadine works by preventing and stopping hay fever symptoms by blocking histamine receptors in the spinal cord. Fexofenadine is highly effective and regarded as one of the most reliable hay fever treatments; especially in the treatment of chronic symptoms.

Fexofenadine can be taken as a one-off dose for relief from occasional hay fever symptoms. For chronic, persisting symptoms you may be advised by your doctor or pharmacist to take fexofenadine on a daily basis. In the anticipation of a high pollen count or increased exposure to a particular allergen, you may be advised to take fexofenadine on a daily basis for an extended period of time.
