Fexofenadine is a type of non sedating antihistamine which is often used for hayfever, allergies and allergy related skin reactions (hives or urticaria).
Fexofenadine is used to treat the symptoms of hayfever, allergies and allergy related skin reactions.
Antihistamines mainly work against chemicals in the body called histamines. These are produced in response to injury or inflammation of the cells in the body. In allergic conditions such as hayfever, these histamines are unnecessarily produced and give rise to symptoms such as sneezing and itchy eyes.
Fexofenadine starts to work within 1 hour reaching maximum effect after 6 hours. The effects last for 24 hours.
Fexofenadine comes in 120mg and 180mg tablets. The usual recommended dose is 180mg tablet taken daily before a meal. However you should follow your doctor's instructions on how to take this medication.
