Product Description

What are Piriteze allergy tablets used for?

  • Treating allergies such as hay fever, pet allergies and dust mite allergies (seasonal and perennial allergic rhinitis).
  • Treating itchy, nettle-type, allergic skin rashes (urticaria or hives).
  • Treating a chronic itchy nettle-type rash where the cause isn’t known (chronic idiopathic urticaria).

Piriteze allergy tablets contain 10mg cetirizine and are suitable for adults and children aged six years and over.

How do Piriteze allergy tablets work?

Piriteze allergy tablets contain the active ingredient cetirizine hydrochloride, which is a type of medicine called a non-sedating antihistamine.

Cetirizine works by preventing the actions of histamine – a substance produced by the body when it reacts to a foreign substance, such as pollen or pet fur (these are known as allergens). Histamine causes a chain reaction that results in allergic symptoms such as itchy eyes, sneezing and a runny nose. Cetirizine blocks histamine receptors and so stops this chain reaction.

Cetirizine can also be used to relieve the symptoms of a condition called chronic idiopathic urticaria. This is a chronic itchy rash, similar to nettle rash, but with no apparent cause. Blocking the actions of histamine relieves the itching and reduces the rash associated with this condition and other allergic skin reactions.

How do I take Piriteze allergy tablets?

  • You can take a dose of this medicine as needed to relieve occasional allergy symptoms once they’ve started. Or you can take it in anticipation of getting allergy symptoms, for instance you can take a dose before leaving the house if you know there will be a high pollen count, or if you’re visiting friends with a pet you’re allergic to. You can also take it regularly every day to prevent symptoms, for example during the pollen season.
  • The usual dose for adults and adolescents aged 12 years and over is one tablet once a day.
  • Children aged 6 to 12 years should be given half a tablet twice a day.
  • The tablets should be swallowed with a drink. They can be taken either with or without food, on a full of empty stomach.
  • If symptoms persist despite treatment, get advice from your doctor or pharmacist.

What should I know before taking Piriteze allergy tablets?

  • Although cetirizine is a non-sedating antihistamine, occasionally some people may find it makes them feel slightly sleepy. Make sure you know how this medicine affects you before doing potentially hazardous activities such as driving, riding bikes or operating machines. If you do find this medicine makes you sleepy you should avoid drinking alcohol or using other medicines that cause drowsiness with it, as this could make any sleepiness or reduced alertness worse.
  • If you’re due to have any skin prick or patch tests to diagnose allergies you should stop taking this medicine at least three days before the tests. This is because antihistamines can prevent or lessen the skin reactions that indicate an allergy, and so can make the test results unreliable.

Who shouldn’t take Piriteze allergy tablets?

  • Children under six years of age. Liquid forms of cetirizine are available for younger children – see end of page.
  • People with severe kidney failure requiring dialysis.
  • People who are allergic or intolerant to any ingredient of the medicine. Check the ingredients listed in the leaflet that comes with the medicine if you know you have specific allergies or intolerances.
