Overview

Glencet 5mg Tablet contains Levocetirizine 5mg, a second-generation antihistamine used to relieve symptoms of allergic conditions such as allergic rhinitis (hay fever) and chronic urticaria (hives). It is the active R-enantiomer of cetirizine, offering effective relief from sneezing, runny or itchy nose, itchy or watery eyes, and itchy skin or hives caused by allergic reactions, with a low tendency to cause drowsiness compared to older first-generation antihistamines.

Despite Levocetirizine being a drug class that is often available without a prescription in many markets, Glencet 5mg Tablet is specifically classified as requiring a doctor’s prescription for this brand and listing on DoctorOnCall. A doctor’s assessment helps confirm the diagnosis and ensures the medicine is appropriate for the individual. Through DoctorOnCall, customers can complete an online consultation with a registered doctor who will review their symptoms and, if appropriate, issue a prescription so the medicine can be dispensed safely.

How it Works

Levocetirizine works by selectively blocking histamine H1 receptors, preventing histamine (a chemical released during allergic reactions) from binding to these receptors and triggering symptoms such as itching, sneezing, nasal congestion, and swelling. By blocking this pathway, Levocetirizine helps reduce the intensity of allergic symptoms while causing comparatively less sedation than older antihistamines, as it crosses into the brain to a lesser extent.

Directions for Use

Glencet 5mg Tablet should be taken exactly as directed by the prescribing doctor, typically once daily, with or without food, and swallowed with a glass of water. It may be taken in the evening if drowsiness is a concern for some individuals, and the doctor’s instructions on duration of treatment should be followed, particularly for chronic conditions like ongoing urticaria.

Dosage

The standard adult dose is one 5mg tablet once daily, as prescribed by the doctor, with dose adjustment required for patients with reduced kidney function. Dosing in children and elderly patients may differ and should follow the prescribing doctor’s specific instructions rather than the standard adult dose.

Shelf Life

Glencet 5mg Tablet should be used before the expiry date printed on the blister strip and outer carton. Do not use the tablets beyond this date, as effectiveness cannot be guaranteed thereafter.

Storage Instructions
