Description for Telfast 120mg tablets

Hay fever is an allergic reaction to pollen or dust affecting around 20% of people in the UK. It occurs when an allergen such as pollen enters your system through the nose or eyes, causing symptoms such as coughing, sneezing, a blocked or runny nose, and itchy or red eyes. While there is no cure for hay fever, you can treat the symptoms with a medicine such as Telfast. 

Telfast contains fexofenadine hydrochloride, an antihistamine that combats symptoms of hay fever and other allergic reactions. Consult with our online doctor today and receive same-day dispatch before 4pm on all UK orders.

What is Telfast 120mg?

Telfast is an antihistamine that provides quick and effective relief from the symptoms of allergic rhinitis, also known as hay fever.

Hay fever is caused by the release of histamine, a chemical made by the body in reaction to an allergen such as pollen or dust. This causes inflammation, which leads to the symptoms of hay fever.

Telfast is effective at preventing this because it contains fexofenadine hydrochloride, an antihistamine. This means that it stops histamine from causing the symptoms associated with hay fever.


What are Telfast 120mg tablets used for?

Telfast is most commonly used to treat the symptoms of hay fever. However, as it contains the antihistamine fexofenadine hydrochloride, it is also effective against other allergies such as dust mites and pets dander.

If additional allergy relief is needed, Telfast tablets can be taken alongside a nasal spray or eye drops. You may find the combination gives you more hay fever relief than either treatment on its own.


Hay fever symptoms

The symptoms of hay fever include:

  • Coughing or sneezing
  • Itchy, watery or red eyes
  • Blocked or runny nose, often accompanied by a loss of smell
  • Discomfort in the mouth, throat, ears or nose
  • Head or earache
  • Fatigue

Asthma sufferers might also experience the following hay fever symptoms:

  • Tightness in the chest
  • Increased coughing and wheezing
  • Difficulty breathing or shortness of breath


Telfast alternatives

There are some non-medicinal methods to help you combat symptoms of allergies, such as:

  • Wearing wrap-around sunglasses.
  • Keeping windows closed on days with a high pollen count.
  • Showering as soon as you return home. This will remove any trapped pollen grains from your hair or skin. 

You can also try using other prescription treatments or over the counter products such as:

You should try these before moving onto a prescription only medicine.


Fexofenadine hydrochloride and high blood pressure

There is no link between fexofenadine hydrochloride and high blood pressure.


Antihistamines and alcohol

Alcohol is known to increase the side effects of fexofenadine hydrochloride, and so alcohol should be avoided when taking Telfast. If you are going to drink on antihistamines, do so only in moderation and continue to monitor your reactions.


Fexofenadine hydrochloride and asthma

Antihistamines such as Telfast are generally fine for asthmatics to take. However, they can cause side effects in some cases. If you find yourself suffering any adverse side effects, consult your pharmacist or GP immediately.


Pregnancy and breastfeeding

Fexofenadine hydrochloride should not be taken by women who are pregnant or breastfeeding unless they have spoken to their GP first, Otherwise, try using an alternative remedy instead such as eye drops or nasal spray.

    If you have no adverse effects and your hay fever is well controlled, you can log in and easily re-order another supply.

  • What do Telfast tablets contain?

    The active ingredient in Telfast is an antihistamine called fexofenadine hydrochloride. Each tablet contains either 120mg or 180mg. Telfast also contains several inactive ingredients. For more details, please see the ‘Ingredients’ tab above.

  • How do Telfast tablets work?

    The active ingredient is fexofenadine hydrochloride, an antihistamine. Histamine is one of the chemicals the body releases in response to allergens. It causes skin irritation and the inflammation of the nasal passages. Fexofenadine reduces the production of histamine, which treats the symptoms of rhinitis.

  • Are Telfast tablets available for next-day delivery?

    Yes – we understand that sometimes you will want your treatment as soon as possible. If ordered before 4pm Monday to Friday, Telfast is available for next-day delivery.

    • A wealth of information - we provide all the information you could need on Telfast and other allergy treatments, in easy to digest formats, at a time that suits you.
  • I normally get Telfast tablets from my doctor - why should I buy it online?

    Telfast is available on the NHS from your GP if you have been diagnosed with breathing problems due to allergies. This is normally where we suggest people start their treatment, to ensure that their condition is properly diagnosed and any possible serious symptoms are addressed.

    Many people can find it difficult to fit in time to see their GP or hard to get an appointment at all! It can, therefore, be more convenient to order your treatment online and have it delivered to your home or work address with minimum fuss. We also provide complete support to allow you to get any questions answered by our professional team by phone, email or live chat.

  • Can Telfast make you drowsy?

    The active ingredient in Telfast, fexofenadine, is officially labelled as a non-drowsy antihistamine. However, some people occasionally find that it still makes them feel drowsy. Do not drive or operate heavy machinery when first taking Telfast to make sure your reactions are normal.

  • Can Telfast cause weight gain?

    According to the NHS, fexofenadine isn't known to cause weight gain and it is not listed as a side effect in the information leaflet, meaning it hasn't been observed as a significant effect in studies so far. There have been some studies that have shown that antihistamines can cause weight gain in some people. This is possibly due to an increased appetite caused by the antihistamine. To counter this, if you experience weight gain when taking an antihistamine, try other hay fever remedies such as nasal sprays or eye drops instead of tablets.

  • Can Telfast cause insomnia?

    Some patients have reported insomnia when taking antihistamines like fexofenadine - it is listed as an uncommon side effect in the patient information leaflet. To counter this, take Telfast in the morning rather than at night.

  • Can Telfast cause diarrhoea?

    In some cases, Telfast can cause diarrhoea in sufferers. This rare, but if it occurs, consult with your pharmacist or GP.

  • Can I take Telfast when breastfeeding?

    Fexofenadine hydrochloride should not be taken if you are breastfeeding without speaking to your GP first. Alternatively, try another allergy remedy such as eye drops or nasal spray.

  • Can I take Telfast during pregnancy?

    If you are pregnant, you should first talk to your doctor before taking fexofenadine hydrochloride. Alternatively, try other remedies such as nasal sprays or eye drops instead.

  • Can I take Telfast with citalopram or sertraline?

    Taking antihistamines with any SSRI antidepressants such as sertraline or citalopram can intensify side effects, such as drowsiness or fatigue. You should always check with your doctor before taking antihistamines alongside antidepressant medication, or try alternative allergy remedies instead.
