Fexofenadine

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.

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.
