Letizen S (Cetirizine Dihydrochloride)

Cetirizine works by selectively blocking peripheral histamine H1 receptors. This prevents histamine released during an allergic response from binding to its receptors, thereby reducing vasodilation, increased permeability and nerve stimulation that cause typical allergy symptoms.

The appropriate dose of Letizen S is determined by a prescriber based on the patient’s age, weight, renal function and the severity of symptoms. Healthcare professionals follow local labeling recommendations when deciding the exact amount and frequency.

Safety data for cetirizine in pregnancy are limited, so pregnant women should only use Letizen S if the potential benefit outweighs any risk and after consulting their doctor. While small amounts are excreted in breast milk, nursing mothers should seek medical advice before use.

To order Letizen S, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Letizen S (cetirizine) is a second‑generation antihistamine that generally causes less sedation than first‑generation agents such as diphenhydramine. Compared with another second‑generation option, loratadine, cetirizine may have a slightly faster onset of action but a similar safety profile.

Store Letizen S at ambient temperature, preferably below 25 °C. Keep the tablets in the original blister pack or container, protect them from moisture and direct sunlight, and keep out of reach of children.

Letizen S is taken orally, usually with a glass of water. It can be taken with or without food, depending on the prescriber’s advice, and should be swallowed whole without crushing or chewing the tablet.

The most serious risks include rare allergic reactions such as anaphylaxis, severe skin conditions like Stevens‑Johnson syndrome, and angioedema that can affect breathing. Immediate medical attention is required if any of these symptoms appear.

Individuals with known hypersensitivity to cetirizine or any component of the formulation should avoid Letizen S. Caution is also advised for patients with severe renal impairment, and it should be used only under medical supervision in pregnant or breastfeeding women.
