Buy Treathay Fexofenadine 

Treathay Fexofenadine is a hay fever treatment containing 120mg of the non-drowsy antihistamine fexofenadine hydrochloride. It can relieve hay fever symptoms, such as sneezing, runny nose and itchy eyes. 


How Treathay Fexofenadine works

Fexofenadine is a non-drowsy medicine known as an antihistamine. When you come into contact with something you’re allergic to, such as pollen, your body produces a substance called histamine, which causes watery eyes and itchy skin, to name just a few symptoms. 

Fexofenadine works by blocking the effects of histamine to reduce any unpleasant symptoms.



Always take Treathay Fexofenadine exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you.  

For adults and children aged 12 years and over, take one tablet daily with water before a meal. This medicine should take effect within 1 hour and lasts for 24 hours.


Side effects

Like all medicines, Treathay Fexofenadine may cause side effects in some people, but these won’t affect everybody. Common side effects include: 


  • Headaches 
  • Drowsiness 
  • Nausea 
  • Dizziness


If you experience any side effects, including any not included in the patient information leaflet, you can report them using the MHRA Yellow Card Scheme.


Serious side effects

Seek emergency medical attention if you notice any signs of a severe allergic reaction, symptoms of which include swelling of the face and throat, skin rash, breathing difficulties and/or loss of consciousness. 



Treathay Fexofenadine may be unsuitable for certain people. Do not take these tablets if you are allergic to any of the ingredients.

Talk to your doctor or Chemist4U pharmacist before taking this medicine if: 


  • You have problems with your liver or kidneys 
  • You are elderly 
  • You have or have ever had heart problems 


Using/taking other medicines

If you are taking or have recently taken any medication, including medication obtained without a prescription, talk to your GP or pharmacist before taking this medication. 

If you are taking apalutamide to treat prostate cancer, it may decrease the effect of Treathay Fexofenadine.

Indigestion remedies containing aluminium and magnesium may lower the amount of medication absorbed by this product.

You should leave 2 hours between taking Treathay Fexofenadine and your indigestion remedy.

This product is not suitable for children under 12 years old.

Treathay Fexofenadine should not be taken during pregnancy or breastfeeding unless advised by a medical professional to do so. If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, you must ask your doctor or Chemist4U pharmacist for advice before taking any new medicine.

In some cases, Treathay Fexofenadine may cause you to feel dizzy or drowsy. If you are affected, do not drive or operate machinery until you feel safe enough to do so.
