Lecisyn (Levocetirizine Dihydrochloride)

Levocetirizine selectively blocks peripheral H1 histamine receptors, preventing histamine from binding and triggering the cascade that leads to vasodilation, increased vascular permeability, and nerve stimulation, thereby diminishing the typical signs of an allergic response.

The appropriate dose of Lecisyn is determined by the prescribing healthcare professional based on the patient’s age, severity of symptoms, renal function and other clinical factors. The prescriber will set the exact regimen for each individual.

Safety data for levocetirizine in pregnancy and lactation are limited. It should only be used when the potential benefit justifies any possible risk to the fetus or infant, and this decision must be made by a qualified healthcare provider.

To place an order, submit an enquiry on the Lecisyn 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.

Levocetirizine is a second‑generation antihistamine offering less sedation than first‑generation agents such as diphenhydramine. Compared with cetirizine, it provides similar efficacy with a slightly lower incidence of drowsiness, making it a preferred option for patients needing daytime symptom control.

Lecisyn tablets should be stored at temperatures below 25 °C, in their original packaging, and protected from moisture and direct sunlight. Do not store in a refrigerator or freezer unless specifically instructed by the supplier.

Lecisyn is taken orally as a tablet. The tablet should be swallowed whole with a glass of water, with or without food, according to the prescriber’s instructions.

Serious adverse reactions, although rare, include angioedema, anaphylaxis, severe skin reactions such as Stevens‑Johnson syndrome, hepatic dysfunction and hematologic abnormalities. Patients should seek immediate medical attention if they experience swelling of the face or throat, rash, or unexplained bruising.

Lecisyn should be avoided in individuals with known hypersensitivity to levocetirizine, other piperazine antihistamines, or any of the tablet’s excipients. It is also contraindicated in patients with severe renal impairment unless dose adjustment is made under medical supervision.
