Letizen (Cetirizine Dihydrochloride)

Cetirizine works by selectively blocking peripheral histamine H1 receptors. By preventing histamine from binding to these receptors, it stops the cascade that leads to increased vascular permeability, nerve irritation, and smooth‑muscle contraction, thereby alleviating typical allergy symptoms.

The appropriate dose of Letizen is determined by a qualified prescriber based on the patient’s age, weight, renal function and the specific indication. Healthcare professionals tailor the regimen to achieve optimal symptom control while minimizing potential side effects.

Safety data for cetirizine in pregnancy and lactation are limited. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss the potential risks and benefits with their healthcare provider before starting Letizen.

Letizen (cetirizine) is a second‑generation antihistamine, offering effective allergy relief with a lower incidence of sedation compared with first‑generation agents such as diphenhydramine. Its once‑daily dosing and favorable safety profile make it a common choice for both seasonal and perennial allergic conditions.

Letizen should be stored at ambient temperature below 25 °C. Keep the tablets in their original packaging, protect them from moisture and direct sunlight, and ensure the container is tightly closed to maintain product stability.

Letizen is taken orally, usually with a glass of water. It can be taken with or without food, as directed by the prescribing clinician. Swallow the tablet whole; do not crush or chew unless specifically instructed.

While rare, serious adverse reactions to Letizen can include severe skin reactions such as Stevens‑Johnson syndrome, angioedema (swelling of the face, lips or tongue), and anaphylaxis. Immediate medical attention is required if any of these symptoms develop.

Individuals with known hypersensitivity to cetirizine or any component of the formulation should not use Letizen. Caution is also advised for patients with severe hepatic impairment, and it should be used only under medical supervision in pregnant or nursing women.
