Levocetirizine Viatris (Levocetirizine Dihydrochloride)

Levocetirizine works by selectively blocking peripheral H1 histamine receptors. This prevents histamine released during allergic reactions from binding to its receptors, thereby reducing vasodilation, increased vascular permeability, and sensory nerve activation that cause typical allergy symptoms.

The exact dose is determined by the prescribing healthcare professional based on the patient’s age, clinical condition, and renal function. In many regions, the standard adult regimen is one tablet taken once daily, but the prescriber may adjust the dose as needed.

Safety data for Levocetirizine in pregnancy and lactation are limited. It should only be used if the potential benefit justifies the potential risk to the fetus or infant. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss use with their physician.

Levocetirizine is a second‑generation antihistamine, offering effective allergy relief with a lower incidence of sedation compared with first‑generation agents like diphenhydramine. Compared with cetirizine, its enantiomer, levocetirizine may provide similar efficacy at a lower dose and slightly reduced drowsiness, though individual responses vary.

Store the tablets at ambient temperature, preferably below 25 °C. Keep them in the original container, protect from moisture and direct sunlight, and ensure the packaging remains tightly closed until use. Do not store in a refrigerator or freezer.

Levocetirizine Viatris is taken orally, usually as a tablet. It should be swallowed whole with a glass of water. The medication can be taken with or without food, but patients should follow the prescriber’s instructions regarding timing and any specific dietary considerations.

While rare, serious adverse events include angioedema, anaphylactic reactions, severe skin reactions such as Stevens‑Johnson syndrome, and significant hepatic enzyme elevations. Patients should seek immediate medical attention if they experience swelling of the face or throat, rash, or signs of liver dysfunction.

Levocetirizine should be avoided in individuals with known hypersensitivity to levocetirizine, cetirizine, or any component of the formulation. Caution is also advised for patients with severe renal impairment, as dose adjustment may be required, and for those taking interacting medications listed under major interactions.
