Patient Reviews: How Fexofenadine Has Made a Difference

What is Fexofenadine?

Fexofenadine is a type of antihistamine that helps combat allergy symptoms. Fexofenadine 120 mg tablets are commonly used to treat hayfever (allergic rhinitis) providing relief from an itchy, runny, or blocked nose, itchy, red, watery eyes, and sneezing. 

Unlike some other antihistamine tablets, Fexofenadine is non-drowsy, so it can be a better option if you need to take antihistamines while working or carrying out daily activities.

How does Fexofenadine 120 mg work?

Fexofenadine 120 mg works and contains the active ingredient fexofenadine hydrochloride. It works by blocking histamine receptors in your body, counteracting the effects of histamine. Histamine is a chemical released by your immune system that causes allergy symptoms when it binds with its receptors.

Fexofenadine Key Features

  • Fast-Acting Allergy Relief: Fexofenadine works quickly to alleviate allergy symptoms such as sneezing, itchy and watery eyes, runny nose, and nasal congestion, allowing you to carry on with your daily activities.
  • Non-Drowsy Formula: Unlike many other antihistamines, Fexofenadine 120 mg is non-drowsy. This makes it a popular solution for anyone who needs to remain focused throughout the day.
  • Long-Lasting Effectiveness: Fexofenadine 120 mg is an extended-release formula, so a single dose provides relief for up to 24 hours.
  • Suitable for Allergy Season and Beyond: Fexofenadine provides relief from a wide range of allergies, including hay fever, pet dander, and dust mites.
  • Trusted and Clinically Proven: Fexofenadine is a trusted, safe and effective medication that has been extensively tested in clinical trials.

By blocking the histamine receptors, Fexofenadine prevents histamine from binding and effectively mitigates its effects, providing fast, effective relief from hayfever symptoms.

When do you need to take antihistamines for hay fever in the UK?

If you need to take antihistamines to relieve hayfever symptoms, you have an allergy to pollen. 

Pollen is released by plants for reproduction and is at its highest levels during spring and summer in the UK. It is advisable to start antihistamine treatments a few weeks before hay fever season to block the histamine reaction entirely or to lessen the severity of symptoms.

How long does Fexofenadine take to work?

Fexofenadine 120 mg typically takes around an hour to start working against hayfever symptoms and lasts for up to 24 hours. It's advisable to take Fexofenadine at least an hour before going outside during the peak of the hay fever season.

How to take Fexofenadine?

The recommended dose of Fexofenadine 120 mg is one tablet per day. Swallow the tablet whole with a glass of water, before a meal, and preferably at the same time every day to help you get into the habit of taking it daily. 

You should start taking Fexofenadine around the time or just before you usually get hayfever symptoms and continue taking them until your symptoms usually stop. 

In the UK, this is usually mid-September, depending on the weather. If you are unsure how to take Fexofenadine 120 mg tablets, consult one of our clinicians or ask a pharmacist for guidance.

What happens if I miss a dose of Fexofenadine?

If you miss a dose of Fexofenadine, do not take a double dose to make up for the missed dose. Just skip the missed dose and take the next one at the usual time.

What happens if I take more Fexofenadine than I should?

If you take too many Fexofenadine 120 mg tablets you should speak to your doctor or go to A&E straight away. The symptoms of a fexofenadine overdose are:

  • Drowsiness
  • Dizziness
  • Dry mouth
  • Fatigue

What’s the difference between Fexofenadine 120 mg and 180 mg tablets?

Fexofenadine 120 mg tablets are the usual dose prescribed to treat hay fever or allergy symptoms. These are available over the counter without a prescription.

Fexofenadine 180 mg tablets are usually prescribed to treat hives (urticaria) in adults and children 12 years and over. You will need a prescription for Fexofenadine 180 mg tablets.

How to buy Fexofenadine 120 mg tablets

Fexofenadine 120 mg tablets are available over the counter without a prescription. You can buy Fexofenadine 120 mg tablets online from Prescription Doctor. You will need to answer a short medical questionnaire, so our clinician can assess if Fexofenadine is right for you.

If Fexofenadine is suitable for you, orders approved by 3 pm will be dispatched the same day and delivered the next day.

All orders are sent in discreet, opaque, and tamper-proof packaging to maintain your privacy.

If our clinicians do not think Fexofenadine 120 mg tablets are right for you, you will receive a full refund as part of the Prescription Doctor money-back guarantee.

Alternative Brands

Fexofenadine 120 mg is the generic form of fexofenadine hydrochloride. It is available under the brand names Telfast and Allevia and is a non-sedating antihistamine that effectively relieves the unpleasant symptoms of hay fever.

There are several alternative hay fever treatments available from Prescription Doctor, from fast-acting antihistamine tablets like Fexofenadine 120 mg to corticosteroid nasal sprays like Beconase which reduces the inflammation in the nasal passage to relieve hayfever symptoms. Find out more about our hayfever options.
