Lecrolyn Sine (Sodium Cromoglicate)

Sodium cromoglicate blocks calcium entry into mast cells, preventing their degranulation. This inhibition stops the release of histamine, leukotrienes and other inflammatory mediators, thereby reducing the allergic response and associated symptoms on the ocular surface.

The dosing regimen for Lecrolyn Sine is determined by the prescribing clinician based on the patient’s age, severity of symptoms and response to therapy. The prescriber will specify the number of drops, frequency and duration of treatment.

Safety data for sodium cromoglicate in pregnancy and lactation are limited. Clinicians should weigh the potential benefits against any possible risks and consider alternative therapies if safety cannot be assured. Consultation with a specialist is recommended.

Compared with antihistamine eye drops, sodium cromoglicate acts upstream by stabilizing mast cells rather than blocking histamine receptors. This can provide longer‑lasting control of inflammation, especially in chronic or seasonal allergy cases, though it may act more slowly to relieve symptoms.

Lecrolyn Sine should be stored at room temperature, below 25 °C, in its original packaging. Protect the bottle from direct sunlight, moisture and extreme temperature fluctuations to maintain product stability.

The product is applied as an ophthalmic solution. The prescriber will instruct the patient to instill the recommended number of drops into the affected eye(s) at the specified intervals, typically avoiding contact lens wear immediately after administration.

Serious but rare risks include severe allergic reactions such as angioedema, corneal ulceration, vision loss and anaphylaxis. Patients should seek immediate medical attention if they experience sudden eye pain, swelling, or visual changes after using the drops.

Individuals with a known hypersensitivity to sodium cromoglicate or any component of the formulation should avoid using Lecrolyn Sine. Additionally, patients with active corneal infections or severe ocular surface disease should be evaluated by an eye specialist before use.
