What Are Fexofenadine 120mg Tablets Used For?
If hay fever leaves you sneezing through spring and summer, you are far from alone. Seasonal allergic rhinitis affects roughly one in five people in the UK, and finding a treatment that works without making you drowsy can feel like a challenge. Fexofenadine 120mg tablets — sold here as Histallay — offer a clinically established, non-sedating option that you can buy over the counter without a prescription. At just £3.38 for a pack of 10, it is an accessible choice for managing day-to-day allergy symptoms. You can browse the full range of allergy and hay fever treatments at Cured Pharmacy if you want to compare your options.
Fexofenadine hydrochloride is the active ingredient in Histallay. It belongs to a class of medicines called second-generation antihistamines, which were developed specifically to reduce the sedating effects associated with older antihistamines like chlorphenamine. The NHS recognises fexofenadine as a non-drowsy antihistamine suitable for relieving the symptoms of hay fever in adults and children aged 12 and over.
How Does Histallay Fexofenadine Work in the Body?
Allergic reactions happen when your immune system overreacts to a harmless substance — pollen, dust mites, pet dander — and releases a chemical called histamine. Histamine then binds to H1 receptors throughout the body, triggering the familiar cascade of sneezing, itching, watery eyes, and nasal congestion. Fexofenadine works by selectively blocking those H1 receptors before histamine can bind to them.
- Fexofenadine is absorbed from the gut and reaches peak plasma concentration within approximately one to three hours of taking a dose.
- It selectively binds to peripheral H1 histamine receptors, blocking the allergic response at source.
- Because it does not readily cross the blood-brain barrier, it causes significantly less sedation than first-generation antihistamines.
- It is largely excreted unchanged, meaning it has a relatively straightforward metabolic profile with fewer drug interactions than some alternatives.
Who Should Use Histallay Fexofenadine 120mg?
This medicine is designed for people who need reliable, day-long allergy relief without the fog of sedation. It is particularly well suited to those who drive, operate machinery, or need to stay sharp at work during allergy season. That said, it is not appropriate for everyone, so it is worth checking the criteria below before purchasing.
- Adults aged 18 and over with seasonal allergic rhinitis (hay fever)
- Adolescents aged 12–17 years experiencing hay fever symptoms
- People who have found older antihistamines too sedating
- Those who prefer a once-daily tablet taken with water rather than a liquid or nasal spray
How Does Histallay Fexofenadine Compare to Other Antihistamines?
| Feature | Histallay Fexofenadine 120mg | Cetirizine 10mg | Loratadine 10mg |
|---|---|---|---|

| Sedation risk | Very low | Low (mild sedation possible) | Low |
| Dosing frequency | Once daily | Once daily | Once daily |
| Suitable age | 12 years and over | 6 years and over | 2 years and over |
Is Histallay Fexofenadine Suitable for Long-Term Use?
Many people use fexofenadine 120mg tablets throughout the entire hay fever season, which in the UK can run from late March through to September depending on which pollens trigger your symptoms. Grass pollen season typically peaks between May and July, while tree pollens arrive earlier in spring. Using fexofenadine 120mg tablets consistently during your personal trigger period is generally considered safe, though you should speak to your pharmacist or GP if your symptoms persist beyond the expected seasonal window or worsen despite treatment. If you also experience itchy or watery eyes alongside nasal symptoms, it may be worth exploring our eye care range for additional relief.
Store Histallay Fexofenadine 120mg tablets below 25°C in a dry place, away from direct sunlight and out of the reach of children. Do not use after the expiry date printed on the packaging.

Specifications of Histallay Fexofenadine 120mg – 10 Tablets
What Is Histallay Fexofenadine 120mg and What Is It Used For?
Histallay Fexofenadine 120mg is an over-the-counter antihistamine tablet used to relieve the symptoms of seasonal allergic rhinitis — more commonly known as hay fever — in adults and adolescents aged 12 years and over. The active ingredient, fexofenadine hydrochloride, works by blocking histamine H1 receptors, reducing the body's allergic response to airborne triggers such as grass pollen, tree pollen, and mould spores. Symptoms it can help with include sneezing, a runny or blocked nose, itchy eyes, and an itchy throat or palate. It is classified as a Pharmacy (P) medicine in the UK, meaning it is available without a prescription but should be purchased from a registered pharmacy.
What Do You Need to Know Before Using Histallay Fexofenadine 120mg?
Before taking this medicine, it is important to check whether it is appropriate for you. There are certain situations where fexofenadine should not be used, and others where extra caution is needed.
Do not take Histallay Fexofenadine 120mg if you:
- Are allergic to fexofenadine hydrochloride or any other ingredient in the tablet
- Are under 12 years of age
- Are pregnant or breastfeeding without first seeking medical advice
- Have severe kidney impairment (renal failure) — seek medical advice before use
Take care and speak to your pharmacist or GP if you:
- Have any kidney problems, even mild ones, as fexofenadine is primarily excreted via the kidneys
- Are taking any other medicines, including herbal remedies or supplements
- Have a heart condition — some antihistamines can affect heart rhythm at high doses
Known drug interactions to be aware of:
- Antacids containing aluminium or magnesium hydroxide — take fexofenadine at least 2 hours before or after these
- Erythromycin and ketoconazole — these can increase fexofenadine plasma levels
- Fruit juices (grapefruit, orange, apple) — significantly reduce absorption; always take with water
How Should You Take Histallay Fexofenadine 120mg?
Always take this medicine exactly as described in the patient information leaflet or as directed by your pharmacist. Do not exceed the stated dose.
- Take one 120mg tablet by mouth once daily.
- Swallow the tablet whole with a full glass of water.
- Do not take with fruit juice — this reduces how much medicine your body absorbs.
- The tablet can be taken with or without food.
- Take at the same time each day to maintain consistent symptom control.
| Indication | Age Group | Dose | Frequency |
|---|---|---|---|
| Seasonal allergic rhinitis (hay fever) | Adults and children aged 12+ | 120mg (1 tablet) | Once daily |
| Seasonal allergic rhinitis (hay fever) | Children under 12 | Not recommended | — |
What Are the Possible Side Effects of Histallay Fexofenadine 120mg?
Like all medicines, fexofenadine can cause side effects, although not everyone experiences them. Most side effects are mild and resolve on their own. If you experience anything severe or unexpected, stop taking the medicine and seek medical advice promptly. If you are managing multiple symptoms alongside hay fever, our ear, nose and throat range may offer complementary relief options.
Common side effects (may affect up to 1 in 10 people):
- Headache
- Nausea
- Dizziness
- Drowsiness (less common than with first-generation antihistamines)
Less common side effects (may affect up to 1 in 100 people):
- Insomnia or sleep disturbance
- Nervousness or fatigue
- Rapid or irregular heartbeat (palpitations)
- Skin rash or itching
Serious allergic reactions (anaphylaxis) are rare but require immediate emergency medical attention. Signs include swelling of the face, lips, or throat, difficulty breathing, or a sudden drop in blood pressure.
How Should You Store Histallay Fexofenadine 120mg?
Correct storage helps maintain the medicine's effectiveness and safety throughout its shelf life.
- Store below 25°C in a cool, dry place
- Keep away from direct sunlight and moisture
- Keep out of the sight and reach of children
- Do not use after the expiry date printed on the packaging
- Do not dispose of medicines via wastewater or household waste — return unused tablets to your pharmacy
If you are looking for additional support during allergy season, you might also find it helpful to explore cold and flu remedies for overlapping respiratory symptoms that can sometimes be difficult to distinguish from hay fever.

Frequently Asked Questions
Where can I buy Histallay Fexofenadine 120mg online in the UK?
You can buy Histallay Fexofenadine 120mg tablets directly from Cured Pharmacy, a GPhC-registered online pharmacy operating in the UK. It is available as an over-the-counter Pharmacy (P) medicine, so no prescription is needed. Simply add it to your basket and complete a short eligibility check at checkout to confirm it is suitable for you.
How does fexofenadine 120mg work in the body?
Fexofenadine works by selectively blocking peripheral H1 histamine receptors, which are the receptors that trigger allergic symptoms when histamine is released in response to allergens like pollen. By occupying these receptors, fexofenadine prevents histamine from binding and causing sneezing, itching, and nasal congestion. Because it does not readily cross the blood-brain barrier, it is far less likely to cause drowsiness than older antihistamines such as chlorphenamine.
How do I take Histallay Fexofenadine 120mg step by step?
Take one 120mg tablet once daily, swallowed whole with a full glass of water — never with fruit juice, as this reduces absorption significantly. You can take it with or without food, and it is best taken at the same time each day to keep symptom control consistent. Do not take more than one tablet in 24 hours unless directed by a healthcare professional.
What is the best time of day to take fexofenadine 120mg?
There is no strict requirement on timing, but many people find taking it in the morning works well, particularly if pollen counts are highest during the day. Taking it at a consistent time each day helps maintain steady levels of the medicine in your system. If you find your symptoms are worse at night, you could try taking it in the evening instead — speak to your pharmacist for personalised advice.
What are the side effects of Histallay Fexofenadine 120mg and how do I manage them?
The most commonly reported side effects include headache, nausea, and dizziness, all of which are generally mild and tend to resolve without treatment. If you experience a headache, staying well hydrated and taking the tablet with food may help. Serious side effects such as palpitations or signs of an allergic reaction are rare, but if they occur you should stop taking the medicine and seek medical advice immediately.
Who is eligible to take Histallay Fexofenadine 120mg?
This medicine is suitable for adults and adolescents aged 12 years and over who experience seasonal allergic rhinitis. It is not recommended for children under 12, and those who are pregnant, breastfeeding, or have significant kidney problems should seek medical advice before use. If you are unsure whether it is right for you, our pharmacists at Cured Pharmacy are available to help — you can also explore our wider allergy and hay fever collection for alternative options.
What happens if I miss a dose of fexofenadine 120mg?
If you forget to take your tablet, take it as soon as you remember — unless it is nearly time for your next scheduled dose, in which case simply skip the missed one. Never take two tablets at once to compensate for a missed dose, as this will not improve symptom control and may increase the risk of side effects. Just continue with your usual once-daily routine from the next day.
Can I take fexofenadine 120mg if I am pregnant or breastfeeding?
The safety of fexofenadine during pregnancy and breastfeeding has not been fully established, so it is not recommended without medical supervision. If you are pregnant or breastfeeding and suffering from hay fever, speak to your GP or midwife before taking any antihistamine. They can advise on the most appropriate treatment for your individual circumstances.
How does fexofenadine compare to cetirizine and loratadine?
All three are second-generation antihistamines used to treat hay fever, but fexofenadine is generally considered to have the lowest sedation risk of the group, making it particularly suitable for people who drive or need to remain fully alert. Cetirizine can occasionally cause mild drowsiness in some individuals, while loratadine is approved for younger children from age two. The best choice depends on your age, lifestyle, and any other medicines you take.
Can I drink alcohol while taking fexofenadine 120mg?
Fexofenadine is a non-sedating antihistamine, so the interaction with alcohol is less of a concern than with older antihistamines. However, alcohol can itself cause drowsiness, and combining it with any medicine is generally not advisable. If you do drink, do so in moderation and be aware of how you feel before driving or operating machinery.
Why can't I take fexofenadine with fruit juice?
Grapefruit, orange, and apple juices contain compounds that inhibit the organic anion transporting polypeptide (OATP) transporters in the gut wall, which are responsible for absorbing fexofenadine into the bloodstream. Drinking these juices alongside the tablet can reduce the amount of medicine your body absorbs by up to 36%, significantly reducing its effectiveness. Always take fexofenadine with a full glass of plain water.
How long can I take Histallay Fexofenadine 120mg for?
Fexofenadine 120mg is intended for use during the hay fever season, which in the UK typically runs from late March through to September. Most people use it for the duration of their personal pollen trigger period without issue. If your symptoms persist beyond the expected seasonal window or do not improve after a few days of treatment, speak to your GP or pharmacist for further assessment.
Is fexofenadine 120mg safe to take with other medicines?
Fexofenadine can interact with certain medicines, most notably antacids containing aluminium or magnesium hydroxide, which should be taken at least two hours apart. Erythromycin and ketoconazole can increase fexofenadine blood levels, so inform your pharmacist or GP if you are taking either of these. Always tell your healthcare provider about all medicines, supplements, and herbal remedies you are currently taking before starting fexofenadine.
What are the alternatives to Histallay Fexofenadine 120mg for hay fever?
Alternatives include other second-generation antihistamines such as cetirizine and loratadine, as well as intranasal corticosteroid sprays like beclometasone, which are particularly effective for nasal congestion. For eye symptoms, antihistamine eye drops may provide targeted relief — you can explore our eye care range for suitable options. Your pharmacist can help you decide which approach, or combination of approaches, is most appropriate for your symptom profile.
What does the latest research say about fexofenadine for hay fever?
Fexofenadine has been extensively studied since its introduction and is well established in clinical guidelines as a first-line non-sedating antihistamine for seasonal allergic rhinitis. Research consistently confirms its efficacy in reducing sneezing, rhinorrhoea, and nasal itching with a favourable safety profile compared to first-generation antihistamines. It remains one of the most widely recommended OTC antihistamines by UK pharmacists and GPs for day-to-day hay fever management.
