What is Telfast?
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. It is available in 120mg & 180mg strengths.
What are Telfast 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
Asthma sufferers might also experience the following hay fever symptoms:
- Tightness in the chest
- Increased coughing and wheezing
- Difficulty breathing or shortness of breath
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:
- Over the counter tablets such as cetirizine or loratadine
- Prescription antihistamines, such as desloratidine or levocetirizine
- Prescription eye drops, such as Optilast
- Non-prescription eye drops, such as Opticrom
- Prescription nasal sprays, such as Dymista
- Over the counter nasal sprays, such as Beclometasone Nasal Spray
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.
