Lecrolyn (Sodium Cromoglicate)

Sodium cromoglicate works by stabilizing mast cells in the conjunctiva, preventing them from releasing histamine and other inflammatory mediators. This inhibition reduces the vascular and nerve responses that produce the typical symptoms of ocular allergy.

The dosing regimen for Lecrolyn is determined by the prescribing clinician based on the severity of the allergic condition and patient response. The prescriber will specify the number of drops and frequency appropriate for each individual.

Safety data for sodium cromoglicate in pregnancy and lactation are limited. It should only be used if the potential benefit justifies any possible risk to the fetus or infant, and the decision should be made in consultation with a healthcare professional.

Lecrolyn (sodium cromoglicate) stabilizes mast cells, whereas many alternative eye drops, such as antihistamines, block histamine receptors. Mast cell stabilizers can provide prophylactic control of symptoms, while antihistamines often act more quickly on existing symptoms. Choice depends on clinical judgment and patient needs.

Lecrolyn should be stored at room temperature below 25 °C, in its original container, protected from light and moisture. Do not freeze the solution. Keep the vial tightly closed when not in use and discard any product that appears discolored or contaminated.

Lecrolyn is applied as an eye drop. The patient should wash hands, tilt the head back, pull down the lower eyelid, and instill the prescribed number of drops into the conjunctival sac. Close the eye gently for a few seconds and avoid blinking excessively.

While rare, serious adverse events can include severe allergic reactions such as anaphylaxis, ocular edema, corneal ulceration, and sudden loss of vision. Any sudden or worsening eye symptoms should prompt immediate medical evaluation.

Lecrolyn should be avoided in individuals with known hypersensitivity to sodium cromoglicate or any component of the formulation. Patients with active ocular infections should defer use until the infection is resolved, and contact lens wearers should follow proper lens removal procedures before instillation.
