What is Xyzal?

Xyzal is an antihistamine, which contains the active ingredient, levocetirizine. Xyzal works by blocking the release of histamine, a chemical produced by the body in response to an allergen (such as pollen or dust). Histamine causes symptoms associated with hay fever and allergy, so by blocking histamine, symptoms can be controlled.

What is Xyzal used for?

Xyzal is used to treat symptoms of hay fever and allergy, such as:

  • Sneezing
  • Runny nose
  • Nasal congestion
  • Water or itchy eyes
  • Itchy skin

Xyzal ingredients

Active ingredient: Levocetirizine 5mg

Inactive ingredients: Lactose monohydrate, microcrystalline cellulose, magnesium stearate, colloidal anhydrous silica, titanium dioxide (E171), hypromellose (E464), and macrogol 400

  • Fexofenadine is faster acting than Xyzal
  • Levocetirizine lasts longer than fexofenadine
  • Xyzal is more sedating than fexofenadine
