Summary

  • Levocetirizine is used to treat symptoms of allergic rhinitis, such as sneezing, runny nose, and nasal congestion. It's also used to alleviate itching and swelling associated with chronic urticaria, a type of hives.

  • Levocetirizine works by blocking histamine, a substance in your body that causes allergic reactions. By preventing histamine from binding to its receptors, it decreases inflammation and allergic responses.

  • Levocetirizine is typically taken once a day. Adults and kids 12 and up usually take 5mg once a day, younger kids 6-11 years old take 2.5mg once a day, and the smallest kids 6 months to 5 years take 1.25mg once a day.

  • Common side effects of Levocetirizine include drowsiness, dry mouth, headache, and fatigue. More serious, but rare, side effects can include allergic reactions, severe dizziness, difficulty breathing, heart rhythm disturbances or liver problems.

  • Avoid Levocetirizine if you're allergic to it, or if you have severe kidney problems. It can cause drowsiness or tiredness, so avoid driving or operating heavy machinery after taking it. Also, avoid alcohol or other drugs that make you sleepy while on this medicine.
