Telfast 30mg is a non-drowsy antihistamine used to relieve hay fever symptoms like sneezing, runny or blocked nose, and itchy or watery eyes in children aged 6 to 11 years.
Telfast contains fexofenadine hydrochloride, a type of antihistamine. It works by blocking histamine, which is the substance in the body responsible for allergic symptoms like sneezing, a runny nose, and watery eyes. Unlike some other antihistamines, Telfast is less likely to cause drowsiness, making it suitable for daytime use.
Telfast tablets start working within an hour and provide all-day relief without causing drowsiness.
Telfast is the paediatric formulation of fexofenadine – the same active ingredient used in adult Telfast and Allevia – and is designed specifically for children’s needs, offering safe, reliable allergy control.
Telfast Kids is suitable for children aged 6-11 years with seasonal allergies.
Do not use Telfast if your child:
Speak to your doctor or pharmacist before use if your child has underlying medical conditions or is taking indigestion remedies containing aluminium or magnesium, as they may reduce absorption of Telfast.
If you miss a dose, do not double up. Simply continue with the next scheduled dose.
Telfast is well tolerated and unlikely to cause drowsiness. Like any medication, Telfast can cause side effects, but they are usually mild and temporary.
Common (may affect up to 1 in 10 people):
Uncommon (may affect up to 1 in 100 people):
Rare or unknown frequency:
If your child experiences any signs of an allergic reaction, stop treatment and get medical advice immediately.
For a full list of side effects, check the Telfast 30mg tablets patient information leaflet.
If you notice any side effects, inform your doctor or pharmacist, even if they are not listed here. You can also report side effects directly through the Yellow Card Scheme. Reporting helps to improve the understanding of this medication’s safety.

Telfast usually starts to alleviate allergy symptoms within 1 hour after taking it, providing symptom relief for most of the day.
No, Telfast is a non-drowsy antihistamine and is unlikely to make your child sleepy when taken as directed.
Telfast Kids is a prescription-only medication, and is available from our allergy treatment clinic after a short online consultation with one of our qualified pharmacists. Once approved, your order will be dispensed and delivered quickly and discreetly to your door.
Avoid giving it with indigestion remedies containing aluminium or magnesium. Speak to your pharmacist before combining with other medicines.
It’s best to take Telfast with water. The absorption of fexofenadine tablets is affected by fruit juices like grapefruit or orange juice.
“Telfast 30mg helps your child feel better from hay fever fast, without making them sleepy, so they can enjoy school, playtime, and daily activities as normal.”
