Buy Allevia 120mg Fexofenadine Online

At Prescription Doctor, you can order Allevia hay fever tablets online from a UK-registered pharmacy.

We offer a fast and discreet delivery service on all orders to ensure you get relief from hay fever as quickly as possible.

To begin your order, simply complete our online medical form to be reviewed by our pharmacy team.

What Is Allevia?

Allevia is a fast-acting non-drowsy antihistamine. One Allevia tablet provides 24-hour relief from hay fever symptoms including:

  • sneezing
  • itchy, runny or blocked nose
  • itchy, red and watery eyes

This prescription-strength hay fever tablet is available over the counter from pharmacies, and online from us.

Allevia tablets are free from gluten and lactose.

Prior to Sanofi bringing Allevia to market in 2022, fexofenadine was only available on prescription as a generic, or under brand names such as Telfast.

How Does Allevia Work?

Allevia contains 120mg of fexofenadine hydrochloride. This 2nd-generation antihistamine is less likely to cause drowsiness.

Some people’s bodies treat pollen as a harmful substance. In response, their bodies fire chemicals called histamines to remove the pollen.

This histamine causes symptoms such as sneezing, coughing, itching and watery eyes due to inflammation.

Fexofenadine blocks histamine, preventing the symptoms from developing.

How long does Allevia take to work?

Allevia starts working within 1 hour of taking it.

The effects of Allevia last for up to 24 hours, providing all-day relief from hay fever symptoms.

How To Take Allevia

Instructions on how to take Allevia can be found in the patient information leaflet. Below is the recommended dosage provided.

Take 1 Allevia tablet daily before a meal.

Swallow the tablet whole with a glass of water.

Do not crush or chew Allevia tablets.

Allevia should be taken 1 hour before you plan on going out.

If you are unsure how to take Allevia, consult the patient information leaflet or ask a pharmacist.

What should I do if I forget to take Allevia when I should?

If you forget to take Allevia when you should, skip the missed dose and take your next dose at the usual time.

Do not take more Allevia to make up for a missed dose.

What should I do if I take more Allevia than I should?

If you accidentally take more Allevia tablets than you should, inform your doctor or go straight to your nearest hospital emergency department.

Remember to take the packaging and any remaining medicine with you, so that the doctors treating you know exactly what and how much you took.

Allevia Side Effects and Cautions

You must always read the patient information leaflet enclosed with your medicine before you begin to take it.

The patient information leaflet contains important information about how to take, store, and discard the medicine safely.

You can read the patient information leaflet for Allevia online via the eMC website.

If you have any questions or concerns about any of the information presented in the patient information leaflet, feel free to send a message to our prescriber using the “my chats” section of your Prescription Doctor account.

Who should not take Allevia?

Allevia is not suitable for everyone.

Speak to your doctor or pharmacist before taking Allevia if you:

  • have a problem with your liver or kidneys
  • have ever had heart disease
  • are elderly
  • are pregnant or breastfeeding

Speak to your doctor or pharmacist if you are unsure whether Allevia is safe for you.

Do not drink grapefruit juice, apple juice or orange juice while taking Fexofenadine, as it may increase your risk of side effects.

If you are taking any remedies for indigestion that contain magnesium or aluminium, leave at least 2 hours between taking them and Allevia. This is because some indigestion remedies can reduce the effectiveness of fexofenadine.

Side effects of Allevia

Just like all other medicines, Allevia may cause side effects in some people.

While taking Allevia, be vigilant of any and all side effects that may occur.

If you experience any side effects - regardless of whether they are listed below or in the patient information leaflet - inform a doctor right away.

Side effects of Allevia may include:

  • diarrhoea
  • difficulty sleeping
  • dizziness
  • drowsiness
  • fast or irregular heart beat
  • headaches

This is not a complete list of side effects associated with Allevia. A full list of side effects associated with Allevia can be found within the enclosed patient information leaflet.


Do not take Allevia if you are allergic to fexofenadine or any of the other ingredients listed in the patient information leaflet.

If you experience an allergic reaction after taking Allevia, stop using the medicine immediately. Seek immediate medical attention.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, you should always discuss the safety and risks with your doctor.

Do not take Allevia if you are pregnant or breastfeeding.

Other safety information

When filling out the online medical form, it is imperative that you inform our medical team of all other medicines you are currently taking. This includes medicines that have been prescribed by your doctor, or bought over the counter.

Do not take Allevia past the expiry date printed on the packaging. The expiry date refers to the last day of the specified month. For example, 05/25 means the 31st of May 2025.

Never throw away medicine via household or water waste, as this can harm the environment. Instead, take any unwanted or expired medicines to your local pharmacy and ask them to dispose them safely on your behalf.

Always store Allevia tablets out of sight and reach from children and pets.

Never share your medicine with anyone else, even if they are experiencing the symptoms or have been diagnosed with the same condition as you.
