Lecrolyn (Sodium Cromoglicate)

Sodium cromoglicate stabilizes the membranes of mast cells located in the conjunctiva and cornea. By preventing mast‑cell degranulation, it blocks the release of histamine, leukotrienes, prostaglandins and cytokines that trigger allergic inflammation, thereby reducing ocular redness, itching and swelling without significant systemic exposure.

The dosing regimen for Lecrolyn is determined by the prescribing clinician based on the severity of the allergic condition and patient factors. Typically, one or two drops are instilled into the affected eye(s) as directed, but the exact frequency and duration should follow the prescriber’s instructions.

Safety data for sodium cromoglicate eye drops in pregnancy and lactation are limited. Use is generally reserved for situations where the potential therapeutic benefit outweighs any possible risk to the fetus or infant. The prescriber should evaluate the individual case and discuss any concerns with the patient.

To request Lecrolyn, 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 (including any cold‑chain requirements) and the necessary import documentation.

Lecrolyn (sodium cromoglicate) is a mast‑cell stabilizer, whereas many other ocular antiallergics, such as antihistamine or mast‑cell‑blocking eye drops, act by directly antagonising histamine receptors. Lecrolyn’s mechanism prevents the release of multiple inflammatory mediators, offering a broader anti‑inflammatory effect, but it may act more slowly than fast‑acting antihistamines.

Lecrolyn should be stored at ambient temperature, preferably below 25 °C, in its original container. Keep the bottle tightly closed, protect it from direct light and moisture, and avoid freezing. Do not use the product if the solution appears discoloured or if the container is damaged.

Lecrolyn is applied as an eye drop. The patient should wash hands, tilt the head back, pull down the lower eyelid, and place the prescribed number of drops into the conjunctival sac. The eye should be closed gently for a few seconds to allow absorption, and contact lenses should be removed before instillation and re‑inserted after a short interval.

Serious but rare risks include allergic contact dermatitis around the eye and severe ocular inflammation that may present as persistent redness, pain, or visual changes. If any of these symptoms occur, the patient should discontinue use and seek immediate medical evaluation.

Lecrolyn should be avoided in individuals with known hypersensitivity to sodium cromoglicate or any excipients in the formulation. Patients with active severe ocular infection or uncontrolled ocular surface disease should not use the product until the condition is resolved, and it should be used with caution in children unless specifically prescribed.
