Telfast tablets provide quick and effective relief from the symptoms of allergic rhinitis. These symptoms include; sneezing, congestion, and a runny nose. Telfast has proven an effective treatment for pollen allergies (hay fever), as well as allergies to common household irritants, such as dust mites and pet dander. Its active ingredient is an antihistamine called fexofenadine hydrochloride.
Allergic rhinitis is a very common condition, affecting around 20% of people in The UK. The condition is caused by an overly sensitive immune system. When a harmless allergen, such as pollen, enters the nose, the immune system mistakenly reacts to it, believing it to be something more serious, such as an infection. To protect against this supposed infection, the body will start to produce more mucus, which will lead to nasal congestion and sneezing. Why certain people are more prone to allergies than others is still not completely understood. Though having a family history of the condition can make a person more susceptible. For some people, these symptoms are only experienced during the high pollen season. This form of rhinitis is known as hay fever, or seasonal rhinitis. For other allergy sufferers, where the symptoms are triggered by household irritants, such as dust mites and animal dander, the symptoms can be experienced all year round.
Histamine is a chemical released by the body in reaction to an allergen. It causes inflammation of the nasal passages, which will lead to the symptoms of allergic rhinitis. Telfast tablets are an antihistamine, which means it reduces the body's production of this chemical.
If additional allergy relief is needed, Telfast tablets can be taken alongside a nasal spray or eye drops. Fexofenadine is generally a non-drowsy antihistamine, but may cause drowsiness in some people. For this reason, it is advised to take care if driving or operating machinery whilst taking Telfast.
Telfast tablets should be taken once per day, ideally at a similar time each day. Swallow the tablet whole with a sip of water, before a meal.
Telfast is most effective if taken every day. If you miss a dose, do not double your next dose to compensate.
