Fexofenadine is a highly effective antihistamine treatment for hay fever and allergies. It is available as a tablet to be taken once a day. Fexofenadine is suitable for adults and children.


Fexofenadine is an antihistamine effective against hay fever and allergy symptoms such as runny nose, inflammation and itching of the skin.  These medicines inhibit the effects of a naturally occurring chemical called histamine on our body. Histamine is released when our allergy mechanisms are triggered, fexofenadine stops histamine from binding to the receptors in our body.

Fexofenadine is a prescription-only medicine that offers relief from hay fever and allergic symptoms of perennial rhinitis in adults and children above six years. This medication is also recommended to treat long-term itchy skin rashes or hives in adults and children above twelve years.

Fexofenadine is a non-drowsy antihistamine medication prescribed to those suffering from allergic symptoms of hay fever and perennial rhinitis. People with a hypersensitive immune system are more likely to be affected by this condition. When allergens like pollen, dust mites or pet dander enter the nose, the immune system reacts in the same way as it would to a flu virus. Our body produces extra mucus to protect against allergens, leading to congestion, sneezing or runny nose. The body also has the histamine chemical at this time. Histamine can cause inflammation in your nasal passages and make relaxing and being able to sleep more difficult.

Fexofenadine  is an antihistamine that works selectively on histamine receptors outside the brain. Fexofenadine blocks histamine receptors around the body from being bound by histamine. As Fexofenadine does not cross the barrier between the blood and brain it doesn’t cause drowsiness.  Fexofenadine effectively relieves these allergic symptoms.

By inhibiting the effects of histamine, Fexofenadine relieves allergic symptoms such as inflammation of the nasal passages, watery or itchy eyes, a runny or blocked nose and sneezing. Some allergic reactions also include itching of the skin, rashes and inflammation.  

Fexofenadine is also an excellent remedy for itchy skin rashes called idiopathic urticaria. This allergy is similar to nettle-type hives or rashes. The medication relieves itching and reduces inflammation by blocking peripheral histamine receptors in the human body.

Fexofenadine is an effective medication for those suffering from hay fever and other allergies. Before you take Fexofenadine, here is some essential information about the medicine –
