What is Telfast?
Telfast is the brand name for fexofenadine, which is an antihistamine pharmaceutical drug; it is classified as a second-generation antihistamine.
You can only buy Telfast when you have a prescription from your doctor. Following an online consultation with one of our certified doctors, you can purchase Telfast from Medicine Direct's online pharmacy.
We sell Telfast in packets of 30 tablets, 60 tablets, or 90 tablets, in doses of either fexofenadine 120 mg or fexofenadine 180mg. If you place your order online before 2 PM, we can offer you next day delivery on your medication.
What is Telfast used to treat?
Telfast is used to treat the symptoms of allergies. It contains the active ingredient fexofenadine hydrochloride, which is effective in relieving symptoms of hay fever. It also helps to relieve eczema, hives, conjunctivitis, insect bites and stings and certain food allergies.
It is a non-drowsy antihistamine, meaning it is less likely to cause drowsiness when you take it, compared to other antihistamines.
Who can take Telfast?
Telfast (fexofenadine) is not suitable for everyone to use. Speak to your doctor doctor before taking Telfast if any of these conditions apply to you:
- You have kidney problems
- You have liver problems
- You have suffered an allergic reaction to Telfast or any other medications in the past
- You have, or have ever had, heart problems
- You have epilepsy or any other health problems that may cause seizures
- You are booked in for an allergy test (Telfast may skew the results of these tests)
Telfast is only suitable for adults and children who are aged 12 and older.
It is not usually recommended for people over the age of 65 years old. Speak to your doctor if you are older than 65 and want to start taking Telfast.
Always read the information leaflet, which will come with your medicine, before you start to take it.
Possible side effects
As is the case with any medicine, Telfast does come with the risk of certain side effects, although these will not affect everyone who uses the course of treatment.
The below common side effects happen in more than 1 in every 100 people who take the medicine:
- Headaches
- Feeling dizzy
- Dry mouth
- Feeling sick
- Feeling sleepy
While fexofenadine hydrochloride is generally considered to be very safe, you should speak to your doctor if any of the above symptoms affect you or do not go away.
Please, refer to the Side Effects tab on this page for a list of more serious adverse reactions you may experience while using this medicine.
Telfast Dosage
Always take Telfast exactly as instructed by your doctor. Read the patient information leaflet before you start taking Telfast for full details. Speak to your doctor if you are unsure of how to take this medicine.
The recommended daily dose is fexofenadine 180 mg each day.
Take your tablet before you eat a meal; swallow it whole with a glass of water.
Your symptoms of hay fever or other allergies should start to be relieved after around 1 hour. The effects of the treatment will last for 24 hours.
You may only need to take Telfast on days where your hay fever or other allergies are flaring up. You may also be instructed to take it regularly, to help prevent the symptoms of hay fever or other conditions. This will be advised by your doctor.
What if I take more than I am supposed to?
If you accidentally take more Telfast than you are supposed to, you are unlikely to be harmed. It is a very safe medicine to use, but you should speak to your doctor if you become concerned. You may suffer from certain side effects if you accidentally take too much; contact your doctor if this is the case.
What if I forget to take it?
If you miss a dose, just take the next dose at the usual time as prescribed by your doctor. Do not take an extra dose to try and make up for missing one.
To get into a routine of taking Telfast, try to take it at the same time every day. Some people find it helpful to set an alarm as a reminder.
How to store it
Telfast does not require any particular environment to be stored safely, but it should always be kept out of the reach and sight of children.
Do not use this medication past the expiry date.
