What is Levocetirizine?

Levocetirizine is a non-drowsy antihistamine that provides relief from symptoms of seasonal hay fever. It can also be used to successfully treat dust mite and pet-related allergies, as well as allergy-related rashes on your skin, such as hives and urticaria.

This medicine is only available on prescription and should always be used as directed by your doctor. You can obtain this prescription after completing a free online consultation with HealthExpress.

If your symptoms persist even with treatment, consult your doctor for advice.

How does Levocetirizine work?

Levocetirizine contains levocetirizine dihydrochloride, a type of medicine known as a 'non-drowsy antihistamine'.

Our bodies produce the compound histamine in response to allergens such as pet fur or pollen, causing allergic reactions.

Levocetirizine blocks histamine receptors, preventing the compound from causing uncomfortable symptoms.

This medicine usually starts to work within an hour. However, it may take longer for full relief from symptoms.

How do I take this medication?

There is only one dosage available - 5mg. Each tablet contains 5mg of levocetirizine dihydrochloride and 64mg of lactose monohydrate.

Always follow the instructions detailed in your patient leaflet. You should always follow the advice of the doctor and any dispensing pharmacist.

Treatment duration will depend on the severity of your allergies and symptoms. If you are unsure what is appropriate for you, please consult your GP.

  • you should take 1 tablet daily
  • tablets can be taken with or without food
  • swallow tablets whole, with water
  • you should take doses around the same time daily
  • do not take a double dose; if you forget to take a dose, take the next dose at the usual time

What are the possible side effects?

All medications have the possibility of causing side effects. If you experience any that are particularly severe or distressing, you should stop treatment and inform your doctor.

The most common side effects of this medication include:

  • asthenia (fatigue)
  • drowsiness
  • dry mouth

If you experience any of these side effects, or any not listed, consult your doctor for advice. They may advise you to stop taking this medicine.

You should also stop treatment and seek medical advice if you suspect you are suffering an allergic reaction to the medication.

What precautions should I take?

You should tell your doctor if you are taking any other medicines (including herbal remedies, supplements and non-prescription drugs) as these could impact the effectiveness of Levocetirizine.

Levocetirizine can interact with ritonavir and theophylline, so you should speak to your doctor if you are taking either of these.

You should not take this treatment if you suffer from acute porphyrias.

Although it is a non-sedating antihistamine, some people do find this medication can cause mild drowsiness. You should avoid driving or operating machinery until you are sure of how this medicine affects you.

If you are pregnant, breastfeeding or planning to conceive, you should consult your doctor before taking this medication.

Can I buy Levocetirizine online?

To buy Levocetirizine online, you must first complete a consultation that will be reviewed by one of our doctors. If approved, your medical details will be saved for future use (but never shared).
