Histallay Fexofenadine 120mg Tablets for Allergy Relief

 

You can rely on Histallay tablets to provide effective relief from seasonal and perennial allergic rhinitis symptoms. Each tablet contains 120mg of fexofenadine hydrochloride, a second-generation antihistamine that works by blocking histamine H1 receptors in your body. This action helps reduce the uncomfortable symptoms associated with allergic reactions, including sneezing, runny nose, and itchy, watery eyes.

These tablets are formulated to provide 24-hour symptom control with once-daily dosing. The active ingredient fexofenadine is specifically designed to have minimal penetration across the blood-brain barrier, which means you can take it without experiencing the drowsiness commonly associated with older antihistamines. This makes it suitable for daytime use when you need to remain alert and focused.

 

How Fexofenadine Works in Your System

 

When you encounter allergens such as pollen, dust mites, or pet dander, your immune system releases histamine as part of the allergic response. Fexofenadine works by selectively blocking histamine H1 receptors, preventing histamine from binding and triggering the cascade of symptoms you experience during an allergic reaction.

The medication reaches peak plasma concentrations approximately 2.6 hours after oral administration. Its long half-life allows for once-daily dosing, providing consistent symptom relief throughout the day. Unlike first-generation antihistamines, fexofenadine does not significantly cross the blood-brain barrier, which explains its non-sedating properties.

 

Who Should Consider These Allergy Tablets

 

These tablets are suitable for adults and children over 12 years of age who suffer from allergic rhinitis symptoms. You may find them particularly helpful if you experience seasonal allergies during spring and summer months, or if you have year-round allergies to indoor allergens. For comprehensive allergy management, you might also explore our allergy and hay fever collection for additional treatment options.

The medication is appropriate for people who need to maintain normal daily activities while managing their allergy symptoms. Consider these tablets if you experience:

  • Persistent sneezing and runny nose
  • Itchy, watery eyes
  • Nasal congestion due to allergic reactions
  • Seasonal hay fever symptoms

 

Why Choose Non-Drowsy Antihistamine Treatment

 

The fexofenadine 120mg tablets offer significant advantages over sedating antihistamines, particularly for people who need to drive, operate machinery, or maintain concentration during work or study. Clinical studies have demonstrated that fexofenadine does not impair psychomotor performance or cognitive function at therapeutic doses.

This non-sedating profile makes the medication suitable for long-term use in managing chronic allergic conditions. You can take your daily dose without worrying about afternoon drowsiness or reduced alertness, allowing you to maintain your normal routine while effectively managing allergy symptoms.

 

Storage and Clinical Considerations

 

Store your tablets in their original packaging at room temperature, away from moisture and direct sunlight. Keep them out of reach of children and do not use beyond the expiry date printed on the packaging. The tablets should be swallowed whole with water and can be taken with or without food, though taking them on an empty stomach may result in faster absorption.

Before starting treatment, inform your healthcare provider about any other medications you are taking, particularly antacids containing aluminium or magnesium, as these can reduce fexofenadine absorption. The medication is generally well-tolerated, but individual responses may vary depending on your medical history and concurrent treatments.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

 

Recommended Dosage for Adults and Children Over 12

Take one tablet once daily with water. You can take your tablet with or without food, though absorption may be faster on an empty stomach. Swallow the tablet whole without crushing, chewing, or breaking it. The 120mg strength is specifically formulated to provide 24-hour symptom relief, so you should not exceed one tablet in any 24-hour period.

When and How to Take Your Tablets

For optimal results, take your tablet at the same time each day to maintain consistent levels of the medication in your system. If you are taking antacids containing aluminium or magnesium, leave at least two hours between taking the antacid and your fexofenadine tablet, as antacids can reduce absorption. If you miss a dose, take it as soon as you remember, unless it is almost time for your next dose. Do not take two tablets to make up for a missed dose.

Understanding Potential Side Effects

Like all medicines, Histallay Fexofenadine 120mg tablets can have side effects, although not everyone will experience them. Most people tolerate this medication well, and serious side effects are uncommon. If you do experience side effects, they are typically mild and may include headache, drowsiness, or nausea. For additional support with allergy-related symptoms, you may find helpful products in our eye care collection .

The most commonly reported side effects include headache, which affects approximately 7% of users, and drowsiness, though this occurs less frequently than with older antihistamines. Gastrointestinal symptoms such as nausea may also occur in some individuals.

  • Headache
  • Drowsiness or fatigue
  • Nausea
  • Dizziness
  • Dry mouth
  • Abdominal pain
  • Diarrhoea
  • Sleep disturbances
  • Nervousness
  • Back pain

If you experience these or any other side effects, speak to your doctor or pharmacist right away. For more information about reporting side effects please see the MHRA Yellow Card Scheme.
