What is Telfast?

Telfast is a non-sedating antihistamine. It is used to treat allergies, such as hay fever, conjunctivitis and eczema. The main benefit of this medication is that it alleviates the symptoms of hay fever, without inducing drowsiness. This means it is possible to continue to perform daily activities, including driving and operating machinery, without the discomfort of seasonal allergies.

However, it should also be noted, a very small proportion of those taking Telfast do still experience drowsiness. You should therefore consider your individual reaction to this treatment first, before undertaking any risky activity.

Telfast is also available as a generic treatment, Fexofenadine. Both treatments are identical in their pharmaceutical makeup and the effect they have on the body,

How does it work?

The active ingredient of this medication is the antihistamine 'fexofenadine hydrochloride'. As its name suggests, an antihistamine combats the effects of 'histamine'. This is a compound your body produces when it believes it is under threat from a harmful substance (such as pollen) which causes blood vessels to expand and skin to swell. This swelling results in inflammation in the nasal passage and eyes.

Telfast blocks receptors so that histamine cannot induce the uncomfortable symptoms of nasal congestion, sneezing, itchy nose, etc.

How do I take Telfast?

One 120mg tablet should be taken daily, with water and just preceding a meal. It normally takes around 1 hour for effects to be noticed, with symptoms being alleviated for approximately 24 hours. Please do not exceed the recommended dosage of 1 tablet per day. If you miss a dose, continue as normal the following day.

If you find you suffer from any serious side effects, discontinue treatment immediately and inform your doctor.

What side effects are associated with Telfast?

All medications pose a risk of side effects occurring. That being said, Telfast is a relatively user-friendly treatment.

Common side effects, affecting around 1 in 10 users include:

  • Headache
  • Drowsiness
  • Nausea
  • Dizziness

Additional side effects include:

  • Insomnia
  • Sleeping disorders
  • Nervousness
  • Diarrhoea

If you experience any adverse reactions, please discontinue treatment and inform your doctor.

Furthermore, if you experience swelling of the face, lips, tongue or throat, flushing, chest tightness, and difficulty breathing you should seek immediate medical attention as this indicates an allergic reaction, which can be serious.

For a comprehensive list of side effects, please consult the patient leaflet either at the bottom of this page or when you receive your order.

What precautions should I take?

You should always consult your doctor before starting any new prescription medication. However, it is particularly important to inform them if any of the following apply to you:

  • Problems with your liver or kidneys
  • Any heart condition
  • You are elderly
  • You are pregnant, breastfeeding, or planning to conceive

Can I buy Telfast online?

Yes. You can buy Telfast online through HealthExpress. All we ask is that you complete a confidential consultation. This will allow our doctors to determine whether you have any preexisting conditions or risk factors that may make the treatment unsuitable for your use. If they approve, you can then expect delivery the very next day.
