About Telfast (Fexofenadine)
Telfast is used to treat the symptoms of both hay fever and rhinitis.
Hay fever is caused by breathing in pollen in the air. The reaction releases histamine in the body, which can cause:
-
Sneezing
-
Runny nose
-
Watery/itchy eyes
-
Hives
Rhinitis is inflammation inside the nose. It happens when the body reacts to pollen, dust or animal skin. Rhinitis may look like the common cold, but its symptoms can also include:
-
Dry cough
-
Facial pains
-
Tiredness
-
Watery/itchy eyes
Hay fever and rhinitis are common. They affect one in five people in the UK. Telfast helps to ease the symptoms of both. Its active ingredient is fexofenadine.
