Key Information
What is Fexofenadine?
Fexofenadine Hydrochloride
Fexofenadine is an antihistamine. Fexofenadine tablets contain fexofenadine hydrochloride 120 mg per dose. Fexofenadine is an antihistamine to treat the symptoms of seasonal allergic rhinitis or hay fever. Fexofenadine is an effective antihistamine especially if you have previously tried other non-prescription antihistamines without success. You can take Fexofenadine alongside a nasal spray for hay fever and eyed drops when necessary.
Fexofenadine is used to treat hay fever in adults and children who are six years of age and over. It is also used for the treatment of long-term itchy nettle-type hives or rash in adults and adolescents twelve years old and over.
Fexofenadine is only available with prescription in the UK. You cannot purchase this medication over the counter.
What are hayfever tablets?
Hayfever (medically referred to as seasonal allergic rhinitis), is an allergy to pollen that is very common and affects about 20% of people in the UK. Hayfever tablets, such as Telfast and Fexofenadine, can help you treat symptoms of hayfever. It usually first occurs in childhood, but can develop at any age, and symptoms include sneezing, a blocked or runny nose, itching in the eyes, ears, throat or lips, coughing, tiredness and wheezing.
How does Fexofenadine work?
Fexofenadine contains fexofenadine hydrochloride, a type of non-sedating antihistamine. It works by preventing the actions of histamine, a substance naturally produced by the body in response to a foreign substance such as pollen. Histamine acts on histamine receptors in the cells, causing a chain reaction that results in allergy symptoms.
In allergic reactions such as hay fever, histamine usually leads to the inflammation of the nose, eyes, or airways, which results in watery, itchy eyes, a runny or blocked nose, and sneezing. In allergic skin reactions, histamine causes the skin to be inflamed, to form rashes, and become itchy.
Fexofenadine blocks the histamine receptors and effectively stops the chain reaction that causes the allergy symptoms. Fexofenadine usually starts becoming effective within half an hour to an hour after taking a dose.
Fexofenadine also relieves itchy skin rash called idiopathic urticaria, which is similar to the nettle-type of hives or rash that is a common symptom when you get a skin reaction for no apparent cause. Fexofenadine blocks the actions of histamine to relieve the itching and reduces the rash that is common with this condition.
What are the benefits of using Fexofenadine?
The main benefit of using Fexofenadine is the relief it provides against the symptoms of hay fever and other allergic reactions.

Usage Advice
How do I use Fexofenadine?
For allergic rhinitis, your doctor may suggest that you take a dose of Fexofenadine only when needed in order to reduce the occasional allergy symptoms. Your doctor may also suggest that you take a dose if you anticipate that you will get the symptoms of hay fever, such as when you became aware that there is an impending high pollen count. If the symptoms of allergic rhinitis are more persistent or frequent, your doctor may recommend that you take Fexofenadine regularly every day during the pollen season in order to prevent your symptoms.
For chronic urticaria, your doctor will ask you to regularly take a dose every day for a certain period of time until the rash shows improvement.
Fexofenadine tablets should be swallowed whole with a sip of water before you eat your meal. This medication is most effective if taken every day for persistent symptoms of allergic reactions. Do not double the dose of Fexofenadine if you miss a dose. Do not compensate for a missed dose.

What is the typical dosage of Fexofenadine?
For hay fever in children aged six to eleven years the recommended Fexofenadine dose is one 30 mg tablet taken twice a day, one in the morning and another one in the evening.

For hay fever in adults and adolescents aged 12 years and over the recommended dose is one 120 mg tablets taken once daily.
