What is Levocetirizine for?

Levocetirizine is a non-drowsy (second-generation) antihistamine medication used to treat and prevent allergic conditions including hay fever (allergic rhinitis) and hives (urticaria). Antihistamines can also be used to manage the symptoms of the common cold such as runny nose and sneezing. Levocetirizine relieves symptoms of itching, runny nose, watery eyes and sneezing. It is an isomer of Cetirizine and hence it has the same pharmacological effects as Cetirizine.

How to use it?

Levocetirizine is taken by mouth as tablets, oral solution, or oral drops. The dose for children older than 12 years old and adults is 5 mg once daily. For children aged 6-11, the dose is 2.5 mg daily. Levocetirizine is usually taken in the evening.

What are the side effects of Levocetirizine?

Levocetirizine has very few side effects. In most people when taken at usual doses, it does not cause any drowsiness. However, some people may experience a small degree of drowsiness. It is best to avoid driving or operating machinery until you know how you respond to Levocetirizine.

Who should not take Levocetirizine?

  • Anyone who is allergic to Levocetirizine, Cetirizine, or any component in the preparation.
  • Anyone with end-stage renal disease.
  • Infants and children 6 months to 11 years old with impaired renal function.
