Buy Xyzal

Xyzal is a medicine containing the active ingredient levocetirizine dihydrochloride, an antihistamine. This medicine is used to treat the symptoms of allergic rhinitis or hay fever, as well as nettle rash (urticaria). Levocetirizine is classed as a non-drowsy antihistamine, so it’s less likely to make you feel sleepy than certain other antihistamines.

How levocetirizine relieves allergy symptoms

Xyzal contains 5mg of the active ingredient levocetirizine dihydrochloride, a type of medicine called an antihistamine. Levocetirizine, and other antihistamines, work by blocking the release of histamine, a chemical that is released during an allergic reaction. Blocking this chemical helps to relieve symptoms such as a runny nose, itchy eyes and sneezing.



Xyzal is a film-coated tablet that should be swallowed whole with a glass of water. The recommended dosage for both adults and children aged 6 years and over is one tablet per day. Xyzal can be taken with or without food and you should follow your doctor or Chemist4U pharmacist’s advice regarding the duration of your treatment.

You should take caution with Xyzal and alcohol - in sensitive patients, taking Xyzal at the same time as alcohol can cause additional reductions in alertness and impairment of performance.


Side Effects

Like all medicines, there is a possibility that Xyzal may cause side effects in some people. If you experience any symptoms of an allergic reaction (swollen face, tongue or throat, trouble swallowing, hives or shortness of breath) seek medical help immediately. Other side effects include: 

  • Dry mouth
  • Headache
  • Tiredness or drowsiness
  • Exhaustion
  • Abdominal pain

For more information on other possible side effects, refer to the patient information leaflet. 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



Xyzal may not be suitable for some people with other health conditions. You shouldn’t use this medicine if: 

  • You are allergic to levocetirizine dihydrochloride, cetirizine, hydroxyzine or any of the other ingredients in this medicine
  • You have a severe impairment of kidney function (severe renal failure with creatinine clearance below 10ml/min)

Talk to your doctor or Chemist4U pharmacist before taking Xyzal if: 

  • You suffer from a condition that means you’re unable to empty your bladder, such as a spinal cord injury or an enlarged prostate
  • You suffer from epilepsy or you’re at risk of convulsions (seizures)
  • You are scheduled for allergy testing
  • You have been told by your doctor that you have an intolerance to some sugars, as Xyzal contains lactose
  • You are taking any other medicines or herbal remedies, including those obtained without a prescription 

Pregnancy and Breastfeeding

If you are pregnant, think you may be pregnant, are trying to become pregnant, or if you are breastfeeding, speak to your doctor or Chemist4U pharmacist for expert advice before taking Xyzal.

Age Restrictions

Xyzal is not recommended for children under the age of 6 years old. If your child is suffering from hayfever or other allergy symptoms, speak to a Chemist4U pharmacist for suitable alternatives or browse our wide range of allergy treatments.

Frequently Asked Questions

What is hay fever?

Hayfever is a common allergy that usually affects people in the spring and summer when plants start to release pollen, a very fine powder that is part of the plant’s reproductive system.

The proteins in pollen can cause your nose, throat, eyes and sinuses to become swollen and inflamed.

Hay fever is usually worse between late March and September in the UK, when the pollen count is at its highest.

Symptoms of hay fever include: 

  • Sneezing and coughing
  • A runny or blocked nose
  • Itchy, red or watery eyes
  • Itchy throat, mouth, nose and ears
  • Loss of smell
  • Pain around the temples and forehead
  • Headache or earache
  • Feeling tired

If you also suffer from asthma, hay fever can also cause a tight feeling in your chest, shortness of breath or wheezing and coughing.
