What is levocetirizine, and what are levocetirizine tablets used for?
Levocetirizine tablets are an antihistamine used to treat allergy symptoms. Common reasons people look for levocetirizine tablets include relief of sneezing, runny or itchy nose, itchy/watery eyes, and other symptoms of seasonal (hay fever) and other allergic conditions.
How do levocetirizine tablets work?
Levocetirizine is a second-generation antihistamine. It works by blocking histamine (H1) activity, which reduces allergy symptoms.
What strength do people typically buy (e.g., 5 mg tablets)?
Levocetirizine tablets are commonly sold in a 5 mg strength for oral use (the exact strengths and brands depend on the country and manufacturer).
How should levocetirizine tablets be taken?
Take levocetirizine tablets by mouth as directed by the label or a clinician. Dosing can vary by age and the specific allergy being treated, so follow the instructions on your prescription or package.
Can levocetirizine cause drowsiness?
Levocetirizine can cause drowsiness or fatigue in some people, though it is generally considered less sedating than older antihistamines. Avoid driving or operating machinery if you feel sleepy after taking it.
Who should be careful or ask a doctor first?
People with kidney problems may need dose adjustments because levocetirizine is cleared through the body in a way that can be affected by renal function. Anyone who is pregnant, breastfeeding, or taking other medicines should check with a clinician before starting.

Common side effects can include drowsiness, dry mouth, fatigue, headache, and dizziness. Seek medical advice if you develop more serious reactions such as swelling, rash, or breathing difficulty.
