MONTELUKE AXL

Levocetirizine tablet Levocetirizine tablet is an antihistamine that treats allergy symptoms including runny nose, sneezing, itchy/watery eyes, and hives. It blocks histamine (H1) receptors and prevents sneezing, itching, watery eyes, runny nose and skin rashes caused by allergies. Levocetirizine is the active isomer of cetirizine and provides effective allergy relief at a lower dose. It has a rapid onset of action, usually within 20-60 minutes and effects last up to 24 hours with once daily dosing. It is not a cold or flu medicine and it does not treat viral infections, but it may relieve allergy-like symptoms such as sneezing and runny nose that sometimes occur with a cold. It is generally non-sedating for most people but some people may get mild drowsiness, which is why it is often recommended to take at nite.

Product Information

What Is Levocetirizine Tablet Used For? 

Levocetirizine tablet uses are centered around allergy relief, not infection treatment—it will not cure a cold, flu, or bacterial infection, but it can reduce allergy-driven symptoms that sometimes overlap with cold-like presentations, such as sneezing and nasal congestion.

How Levocetirizine Tablet Works

Levocetirizine is the active (R)-enantiomer of cetirizine from the second-generation H1-antihistamine class. When the body encounters an allergen, immune cells release histamine, a chemical that triggers sneezing, itching, redness and swelling. Levocetirizine selectively blocks the H1 histamine receptors . When histamine cannot bind to these receptors , it cannot cause these allergic symptoms . It does not easily cross the blood brain barrier as compared to first generation antihistamines and yet provides effective long-lasting relief. It causes less sedation for most users.

4. Is levocetirizine used for sleeping?

No, levocetirizine is not intended as a sleep aid. While mild drowsiness is a possible side effect for some users, it should not be used specifically to help with sleep — a doctor should be consulted for sleep-related concerns.
