Telfast is a type of medication that may be prescribed for people who suffer from hayfever in the summer. Telfast helps to relieve various symptoms such as runny and itchy eyes, blocked or runny nose, sneezing and hives.

How it works

Telfast contains the active ingredient fexofenadine. It belongs to a family of medicines call antihistamines, and relieves various symptoms of hayfever within an hour. The effect can last up to 24 hour.

What are the benefits of Telfast?

Allergies and hayfever may not be life threatening or have a long term impact on your life, but they can be frustrating and an inconvenience, especially if they affect your eyesight. Telfast tackles multiple symptoms of hayfever, unlike some medications which only manage one area.

How to take Telfast.

You should always follow your doctor’s recommendation on taking Telfast, and only use the following information as a guide.

The recommended dose is one 120mg taken once a day, take before a meal if possible. Do not exceed the stated dose.

Is Telfast right for me?

The suitability of Telfast will be assessed by your doctor as there are some medical conditions that mean it may not be right for you. You may not be prescribed the medication if you are allergic to fexofenadine or any of the other ingredients listed in the patient information handbook, if you have severe problems with your liver or kidneys, or have or have had heart disease.

What are the side effects of Telfast?

All medications have side effects but not everyone gets them. You can reduce the risk of side effects by informing your doctor of your full medical history and any other medications you are currently taking. Common side effects of Telfast include headache, drowsiness, dizziness and nausea.

How do I buy Telfast online?

To buy Telfast legally and safely online, you need a prescription from a GMC/EU registered doctor, such as Doctor-4-U. Our online doctor will allow you to request a prescription via a medical questionnaire. If you are deemed suitable for Telfast, your prescription will usually be dispatched within 24 hours. If you are not deemed suitable, you will receive a full refund.
