Letizen (Cetirizine Dihydrochloride)

Cetirizine is a selective peripheral H1‑receptor antagonist. It binds to H1 receptors on mast cells and basophils, blocking histamine from activating these receptors. This inhibition prevents the cascade that causes vasodilation, increased permeability and nerve irritation, thereby reducing typical allergy signs.

The exact dose of Letizen is determined by the prescribing healthcare professional based on the patient’s age, weight, renal function and severity of symptoms. Typical adult regimens involve a once‑daily dose, but the prescriber may adjust frequency or amount as needed.

Safety data for cetirizine in pregnancy are limited, so Letizen should only be used if the potential benefit justifies any possible risk to the fetus. Cetirizine does pass into breast milk; nursing mothers should consult their physician before using the product.

To request Letizen, 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.

Both cetirizine (Letizen) and loratadine are second‑generation antihistamines that cause less sedation than first‑generation agents. Cetirizine may have a slightly faster onset of action and can be more effective for some patients with chronic urticaria, while loratadine is often preferred when minimal drowsiness is a priority.

Letizen tablets should be stored at ambient temperature, preferably below 25 °C (77 °F). Keep the product in its original packaging, protect it from moisture and direct sunlight, and ensure the container is tightly closed to maintain tablet integrity.

Letizen is taken orally with or without food, as directed by a healthcare professional. Swallow the tablet whole with a glass of water; do not crush or chew unless specifically instructed. Consistency in timing helps maintain steady symptom control.

Although rare, serious adverse reactions can include anaphylaxis, Stevens‑Johnson syndrome and significant hepatic dysfunction. Patients should seek immediate medical attention if they experience difficulty breathing, widespread rash, blistering skin lesions or signs of liver injury such as jaundice.

Letizen should be avoided in individuals with known hypersensitivity to cetirizine or any excipients in the tablet. Caution is also advised for patients with severe renal impairment, pregnant or nursing women unless clearly indicated, and those taking medications that may cause dangerous interactions.
