What is Xyzal?

Xyzal is an anti-allergy medication. It is used primarily to treat symptoms of allergic rhinitis. Allergic rhinitis is inflammation of the inside of the nose, caused by an allergen. Common allergens that can cause allergic rhinitis are mould, pollen or flakes of skin from animals. Xyzal can help ease the inflammation caused by allergic rhinitis.

Xyzal is a prescription only medication. You must have a valid prescription before you buy Xyzal. Alternatively, we can prescribe it to you following a brief online consultation. Contact us to find out more.

Xyzal is a brand name - the active ingredient in Xyzal is levocetirizine dihydrochloride. For more information about Xyzal, consult the patient information leaflet.

How it works

Allergic rhinitis is caused by the production of a chemical called histamine in the body. When the body is exposed to an allergen, it produces histamine, and this can make the tissues in and around the nose swell up, causing symptoms of allergic rhinitis. Symptoms of allergic rhinitis can include sneezing, nasal congestion and urticaria (a skin rash).

Levocetirizine dihydrochloride, the active ingredient in Xyzal, is an antihistamine, which will reduce or block histamine, relieving allergy symptoms.

Xyzal should begin working around one hour after taking it.

Before you take it

You should not take Xyzal if you are allergic to the active ingredient levocetirizine dihydrochloride, or any of the other ingredients in this medicine. You may find a full list of ingredients contained within the patient information leaflet. You should take particular care if you have ever had a previous allergic reaction to any other antihistamine medicines.

Xyzal may be unsuitable for patients who are suffering from severe kidney impairment or reduced liver function. If this applies to you, discuss your symptoms with your doctor, who will be able to recommend a suitable alternative medication.

If you are epileptic, or at risk of convulsions, Xyzal may cause seizure aggravation. You must consult your doctor before taking Xyzal, as they will be able to advise as to whether Xyzal is suitable for you to take.

If you are scheduled to be tested for allergies, you should stop taking Xyzal several days before the test, as it may interfere with your allergy test results. You should seek further clarification from your doctor.

Xyzal contains lactose. If you have been told by your doctor that you are lactose intolerant, or have an intolerance to some sugars, you should not take Xyzal and should seek an alternative treatment for your condition.

Antihistamines such as Xyzal can cause drowsiness. You should not drive, operate machinery or do anything that may cause harm to yourself or others before you are fully aware of how this medicine affects you. You should also avoid alcohol while taking Xyzal, as it may cause drowsiness or sleepiness.

Xyzal is not expected to harm an unborn baby during pregnancy. However, you should consult with your doctor before you take this medication if you are pregnant or planning to become pregnant, to check whether it is suitable for you to take.

Xyzal should not be used while breastfeeding, as it can pass into breast milk and may harm a nursing infant.

Xyzal may interact with some other medications. You should tell your doctor if you plan to take Xyzal alongside any of the following:

  • Antidepressants, such as Citalopram or Fluoxetine
  • Ritonavir or Efavirenz to treat HIV
  • Sleeping pills such as Zolpidem or Zopiclone
  • Theophylline to treat airflow obstruction problems
  • Any other antihistamines, such as loratadine or cetirizine

This is not a complete list of warnings and interactions. For a full list, or for advice about taking this medication, you should consult the patient information leaflet or speak with your doctor.

Dosage Instructions

You must always take Xyzal exactly as your doctor or pharmacist has told you. Never exceed the stated dose. If you are in any way unsure of how to take Xyzal, speak to your doctor or pharmacist for clarification.

The typical recommended dose of Xyzal to treat allergic rhinitis is one tablet once per day. You may need to take less than this if you are suffering from kidney impairment or reduced liver function. Your doctor will tell you if this applies to you and how much medication you need to take.

Xyzal tablets must be swallowed whole, with water. Do not suck, crush or chew your tablets. You may take them with or without food.

Store Xyzal in a cool, dry place, free from heat and moisture. Keep it out of the reach of children and pets.

Frequently Asked Questions (FAQs)

Is Xyzal suitable for children?

Xyzal can be taken by adults and children aged 12 years and over to treat symptoms of allergic rhinitis. However, we do not prescribe any medication to anyone under the age of 18.

I’m pregnant. Can I take Xyzal?

Xyzal should not cause any harm to an unborn baby. However, you should speak with your doctor if you are pregnant or planning to become pregnant before taking this medication. Your doctor may only prescribe Xyzal to you during pregnancy if they believe the benefits of taking it outweigh the risks.

What happens if I miss a dose?

If you miss your usual dose of Xyzal, take it as soon as you remember, unless it is nearly time for your next dose. In this case, skip the missed dose and take your next dose as normal.

Never double up to make up for a missed dose. This is especially important if you are on a reduced dose due to impaired kidney or liver function.

What happens if I take too much?

If you take too much Xyzal, you may experience serious side effects such as severe drowsiness or sleepiness. You should contact your doctor if you have taken an overdose of Xyzal, who will decide the appropriate action to be taken.
