Frequently Asked Questions

What is Telfast? 

Telfast is a medication that’s used to combat hay fever and allergic rhinitis. Unlike non-prescription antihistamines, it contains the active ingredient fexofenadine hydrochloride. The increased effectiveness of fexofenadine ensures that it will provide relief even in cases where non-prescription antihistamines and Tesco hay fever tablets proved to be inefficient. 

Telfast can be used by both children and adults (6 years or older) to treat itchy hives or to reduce rashes in teenagers (12 years or older) and adults. 

Since it’s a prescription-only medication  in the United Kingdom, Telfast can’t be bought over-the-counter in the same way that non-prescription antihistamines can. 

How do Telfast tablets work? 

When foreign substances like pollen come into contact with our bodies, our bodies naturally create histamine. In people who suffer from allergies, histamine causes the histamine receptors to react and spark a reaction that leads to allergy symptoms. Telfast is based on a non-sedating antihistamine called fexofenadine hydrochloride. This substance blocks the receptors and prevents the reaction which causes you to experience allergy and hay fever symptoms.

When a person experiences an allergic reaction, histamine causes the airways, eyes and nose to get inflamed. As a result, the person experiencing the symptoms will suffer from itchy and watery eyes, sneezing as well as a blocked or runny nose. In the event of allergic reactions, histamine can result in skin inflammation which then forms into a rash. In most cases, the skin becomes itchy as well.

What fexofenadine does is block the cell’s receptors. This prevents the reaction effectively, so allergy symptoms do not manifest. Typically, it takes about half an hour for fexofenadine to start taking effect after taking the dose.

Telfast is used to reduce or completely remove the following symptoms:

  • Runny nose
  • Itchy eyes
  • Inflammation of the eyes, nose, and respiratory tract
  • Skin rashes
  • Itchiness

Why should I use Telfast? 

The top advantage of taking this medication is the alleviation of symptoms associated with allergic reactions like hay fever. Thanks to Fexofenadine, its active ingredient, it can effectively block histamine action to prevent itching, inflammation, etc.

Telfast tablets improve your quality of life during allergy seasons and enable you to remain functional throughout the day. Unlike other antihistamines, Telfast doesn’t cause you to feel drowsy, which further reduces any discomfort that may be caused by your allergies.

How should Telfast tablets be used? 

Telfast is a prescription-only medication, so you should always listen to your physician’s recommendations when using it. As a general rule, Telfast should either be used to lessen ongoing allergy symptoms, or when you anticipate the onset of your symptoms (for instance, if you’re going to be spending time in an area that has a lot of pollen).

If you are suffering from allergic rhinitis, most doctors will only recommend taking Telfast whenever there is a need for you to reduce the symptoms associated with occasional allergy. You will most likely be advised to take it  whenever you think that hay fever symptoms are going to develop. For instance, if you know that there’s an impending increase in the pollen count in your area, it may be prudent to take it ahead of time.

If case the symptoms associated with your allergic rhinitis tend to become more frequent or persistent, your physician may suggest taking it every day until the pollen season lasts just to make sure that the symptoms are kept under control. If you suffer from chronic urticaria, it’s very likely that you will be advised by your doctor to take it daily for a specific period until your rash improves.

Telfast antihistamine tablets need to be swallowed prior to a meal. They can be swallowed dry or washed down with water, and will usually take about 30 minutes to start working. The tablet is more effective when taken on a daily basis, especially when dealing with allergic reactions that come with persistent symptoms. It is also important not to increase the dose if you skip one. It is never advisable to compensate for any dose you missed.

What's the recommended dosage of Telfast? 

The recommended Telfast dosages are as follows:

  • For hay fever in adults and adolescents aged 12+, the typical dose is a single 120 mg tablet per day.
  • For hay fever in children aged 6-11, the typical dose is a single 30 mg tablet in the morning, and then another 30 mg tablet in the evening.
  • For chronic idiopathic urticaria in adults and adolescents aged 12+, the recommended dose is a single 180 mg tablet per day.

If you happen to forget a dose, simply skip it. You should never double a dose in order to make up for a missed one. 

Want To Know More About Telfast?

Like all medications, Telfast has certain side effects and precautions that need to be taken into consideration. It’s important to note that this medication is intended for adults and children who are 6 years old or older, and should never be given to a child who is younger than 6 years.

You also need to make sure you’re not allergic to any of its ingredients before you start using it, as this can cause a variety of mild and serious symptoms such as difficulty breathing, flushing, chest tightness, facial swelling, and more.

Common side effects of Telfast include:

  • Feeling dizzy
  • Headaches
  • Nausea
  • Feeling drowsy
  • Some patients may also experience the following side effects:
  • Insomnia
  • Restless sleep
  • Palpitations
  • Anxiety
  • Diarrhoea
  • Tachycardia

Although Telfast is a non-sedating antihistamine (ie., it doesn’t make you feel sleepy), there are some individuals who may experience drowsiness as a result of administering the medicine. If this is the case with you, you should avoid consuming alcohol or performing risky activities such as cycling, driving, or operating heavy machinery after you have taken Telfast.

If you have an appointment for allergy testing (such as skin prick tests), you shouldn’t take any Telfast tablets for a minimum of 3 days leading to the tests, as this can cause the tests to produce inaccurate results.

Do not forget to tell your doctor if you’re pregnant, breastfeeding, elderly, or if you’re suffering from epilepsy or cardiovascular disease. Your physician will examine your case and decide whether Telfast is a suitable treatment for your particular condition. 

Furthermore, you should notify your doctor if you’re taking any other medications that may affect or be affected by Telfast. Likewise, don’t forget to consult with your medical practitioner before you begin taking any new medication while you’re also using Telfast.

For two hours after administering a Telfast dose, refrain from using any antacids that contain magnesium or aluminum, as these antacids are likely to make Telfast absorption considerably less effective.

You should be able to safely buy Telfast via online channels. Often, you will need to go through an online consultation with a pharmacist before your order gets processed. This ensures that the medication is indeed right for addressing your particular medical condition.
