Product Description

Levocetirizine Dihydrochloride Tablets IP 5 mg belong to a class of drugs called second-generation antihistamines (anti-allergic agents). As the active R-enantiomer of cetirizine, levocetirizine is primarily used to treat various allergic conditions. 

Allergies occur when the immune system overreacts to harmless foreign substances (allergens) like pollen, dust mites, pet dander, or certain foods, triggering symptoms such as sneezing, itching, or hives. 

It provides relief without significant sedative effects compared to first-generation antihistamines, though mild drowsiness can occur in some individuals.

Uses

Levocetirizine Dihydrochloride 5 mg Tablets are indicated for the treatment of Seasonal allergic rhinitis (hay fever: symptoms like sneezing, runny/itchy nose, watery eyes due to pollen or dust), Perennial allergic rhinitis (year-round allergies to dust mites, pet dander, or mold), Chronic idiopathic urticaria (hives: red, itchy, raised skin patches),

Allergic conjunctivitis (itchy, red eyes), Atopic dermatitis (eczema) or other skin allergies, Reactions to insect bites/stings or mild food allergies (as adjunct therapy)

How it works

Levocetirizine Dihydrochloride 5 mg Tablets block the action of histamine, a chemical messenger released during allergic reactions. By selectively antagonizing peripheral H1-receptors on cells in the nose, eyes, skin, and airways, it prevents histamine from binding and causing symptoms like itching, swelling, sneezing, and a runny nose. It has minimal penetration into the central nervous system, reducing drowsiness compared to older antihistamines, but some sedation may still occur.

Benefits

Levocetirizine 5 mg tablets effectively relieve symptoms of hay fever (seasonal allergic rhinitis), year-round allergies (perennial allergic rhinitis), and urticaria in adults and children aged ≥2 years (adjusted dosing). It quickly (within 1 hour) reduces discomfort from blocked/runny/itchy nose, red/watery eyes, sneezing, and skin rashes, improving daily functioning and sleep quality. Long-term use (up to 6 months) is safe for chronic conditions when prescribed, with once-daily dosing for convenience.
