Fexofenadine

What is Fexofenadine?

Fexofenadine is an orally administered antihistamine drug used to treat a variety of seasonal allergy symptoms such as sneezing, itching, watery eyes, nasal congestion, skin rashes, etc.

Fexofenadine is a third generation antihistamine drug, which is similar to second generation antihistamines including Cetirizine (Zyrtec), Azelastine (Astelin) and Loratadine (Claritin). Fexofenadine has anti-inflammatory properties. It is a reversible competitor at peripheral H1 histamine receptors in the gastrointestinal tract, bronchial smooth muscles and blood vessels. This drug was approved by the FDA in 1995.

How does fexofenadine work?

Most signs of allergic reactions are caused by chemical, histamine. Histamine is released from mast cells, which store histamine. This attaches itself to other cells with stored histamine and activates them. This leads to the release of chemicals that cause symptoms of allergies such as sneezing and itching.

Fexofenadine blocks one type of receptor for histamine and prevents the activation of H1 receptor-containing cells. This leads to temporary relief from the symptoms of allergies. The drug does not cross the blood-brain barrier and would not cause drowsiness.

How to take Fexofenadine

You can find Fexofenadine in the form of tablets in different strengths, such as 60 mg and 180mg. The medication can be taken with water once or twice a day. For better results, avoid taking Fexofenadine with fruit juices as they reduce the absorption of the drug. It is recommended that you consult your doctor before taking the medicine. Your doctor can best evaluate your symptoms and prescribe a suitable dose for you. Make sure you do not take more or less than what is prescribed.

For most seasonal allergies, the recommended dose for adults and children above the age of 12 is 60mg twice a day or 180mg once a day. If you miss a dose, do not double up on your medicine to cover for the missed dose. Stick with your schedule. The tablets must be stored at room temperature and should be kept out of the reach of children.

Before you take Fexofenadine, inform your doctor about any medical condition you have and any other medications you are currently taking. These include nutritional supplements, vitamins, herbal products, etc. Do not use this medication if you are already allergic to chemicals found in the drug.
