What Are Fexofenadine Tablets?
Fexofenadine Tablets are a non-sedating antihistamine medication used to manage allergic reactions. Specifically, hay fever (seasonal allergic rhinitis) responds well to Fexofenadine 120mg tablets, which target symptoms like nasal congestion, sneezing, itchy eyes, and runny nose. Unlike older antihistamines, this treatment allows users to maintain focus during work or daily tasks without drowsiness.
How Do Fexofenadine Tablets Work?
Fexofenadine Tablets contain the active ingredient fexofenadine hydrochloride, which blocks histamine H1-receptors in the body. When exposed to allergens like pollen, your immune system releases histamine – a compound triggering inflammation and allergy symptoms. By inhibiting these receptors, Fexofenadine prevents histamine from binding, effectively reducing symptoms within 60 minutes. For more on histamine’s role, visit the NHS antihistamine guide.
Fexofenadine Tablets Treatment for Hayfever: Key Benefits
- Rapid Symptom Relief: Alleviates sneezing, itchy eyes, and nasal congestion within 1 hour of dosing.
- 24-Hour Protection: Extended-release formula maintains effectiveness throughout the day with a single tablet.
- Zero Drowsiness: Specially formulated to avoid sedation – ideal for driving or operating machinery.
- Multi-Allergy Use: Effective against hay fever (grass/tree pollen), pet dander, and dust mite allergies.
- Clinically Validated: Backed by UK clinical trials and approved for adults/children over 12.
When Should You Use Fexofenadine Tablets for Hay Fever?
In the UK, hay fever season typically spans March to September, with pollen counts peaking on warm, windy days. Starting Fexofenadine Tablets 2-4 weeks before your usual symptom onset (Allergy UK pollen calendar) helps build preventive protection. Daily use during high-risk periods – especially when working outdoors or exercising – minimises histamine responses before symptoms escalate.
How Quickly Do Fexofenadine Tablets Take Effect?
Most users experience noticeable relief within 60 minutes of taking a 120mg dose. For optimal results during peak pollen seasons (May-July), take your tablet 1 hour before outdoor exposure. Effects persist for 24 hours, making morning dosing ideal. Those with severe allergies may combine it with nasal sprays under medical guidance.
How to Take Fexofenadine Tablets
For hayfever relief, take one 120mg Fexofenadine Tablet daily with water before food. Consistency is key – aim for the same time each day (e.g., 8 AM) to maintain 24-hour protection. Begin treatment 2-4 weeks before UK hayfever season (typically March-September) and continue until pollen levels subside. Consult our online clinicians for personalised scheduling advice.
Managing Missed Doses of Fexofenadine Tablets
If you forget a dose, skip it and resume your normal schedule. Never double-dose. Example: If you usually take Fexofenadine Tablets at 8 AM but miss Tuesday’s dose, take Wednesday’s tablet at 8 AM as usual.
Fexofenadine Tablets: Overdose Protocol
Accidental overconsumption (≥2 tablets in 24hrs) requires immediate action:
- Emergency Steps: Contact 111 or visit A&E if experiencing drowsiness, racing heartbeat, or confusion
- What to Bring: Medication packaging and remaining tablets
For non-urgent advice, consult our online doctors or review the NHS Fexofenadine guidelines.

Fexofenadine FAQs
How do Fexofenadine tablets work?
When exposed to allergens like pollen, the body releases histamine which binds to receptors causing allergy symptoms such as sneezing, runny nose and itchy eyes. Fexofenadine hydrochloride blocks histamine from attaching to these receptors, preventing allergy symptoms.
How quickly does Fexofenadine start working?
You'll typically begin feeling relief from allergy symptoms within one hour of taking a dose.
How long does Fexofenadine remain effective?
A single 120mg tablet provides relief from allergy symptoms for up to 24 hours.
What's the proper way to take Fexofenadine tablets?
Take one tablet daily at the same time, with or without food. If you miss a dose, take it when remembered unless it's nearly time for your next dose. Never double-dose to compensate. Consider setting reminders for consistency. Always follow your healthcare professional's instructions.
What should I do if Fexofenadine isn't effective?
Consult your doctor or pharmacist about potentially increasing to 180mg dose. If symptoms persist, they may recommend complementary treatments like nasal sprays (e.g. Beconase, Rhinolast or Nasonex) for enhanced relief.
What's the difference between Fexofenadine, Allegra and Telfast?
Fexofenadine is the active ingredient in both Allegra and Telfast. All three contain identical active components, making them equally effective. Generic fexofenadine tablets typically offer a more cost-effective option.
How should I store and dispose of Fexofenadine tablets?
Store in a cool, dry place away from moisture (not in bathrooms). Keep all medicines securely locked away from children and pets. Dispose of expired medication through pharmacy take-back schemes - never flush down toilets. Consult your pharmacist about local disposal programmes.
How does Fexofenadine compare to other antihistamines?
Fexofenadine is a non-drowsy antihistamine less likely to cause sleepiness compared to sedating antihistamines like Piriton (chlorphenamine).
Does Fexofenadine affect fertility?
Current research shows no evidence that fexofenadine affects fertility. However, consult your GP if you're trying to conceive.
Can I combine Fexofenadine with other hay fever treatments?
Yes, it can be safely combined with other treatments like Beconase nasal spray. Always inform your pharmacist about all medications you're using.
Is alcohol consumption safe with Fexofenadine?
While no serious interactions are known, alcohol may potentially increase the risk of side effects. Exercise caution and monitor your reaction.
Can Fexofenadine be taken long-term?
It's suitable for long-term use during allergy seasons, but should only be taken when experiencing symptoms unless otherwise directed by your doctor.
Does Fexofenadine affect driving ability?
While classified as non-drowsy, individual reactions may vary. Assess your response after first taking it before driving or operating machinery. If experiencing drowsiness, avoid driving.
Is Fexofenadine safe during pregnancy?
Not recommended during pregnancy or breastfeeding unless specifically prescribed by a doctor. The medication passes into breast milk and may affect infants.
Which is more effective: Fexofenadine or Loratadine?
Clinical studies indicate fexofenadine provides superior relief for nasal congestion compared to loratadine.
What's the maximum daily dose of Fexofenadine?
The maximum recommended daily dose is 180mg. Never exceed this without medical supervision.
Are there long-term side effects of Fexofenadine?
No significant long-term side effects are documented. However, seek immediate medical attention if you experience serious reactions like irregular heartbeat, breathing difficulties, or loss of consciousness.
