Lecrolyn (Sodium Cromoglicate)

Sodium cromoglicate stabilizes mast cells in the ocular surface, preventing calcium‑dependent degranulation. This blocks the release of histamine, leukotrienes and other inflammatory mediators, thereby reducing vascular permeability, edema and sensory nerve activation that produce allergic eye symptoms.

The dosing regimen for Lecrolyn is determined by the prescribing eye‑care professional. Typical use involves instilling the recommended number of drops per eye at the frequency indicated on the prescription, which may vary according to severity and patient response.

Safety of sodium cromoglicate ophthalmic solution in pregnancy and lactation has not been fully established. It should be used only if the potential benefit justifies any possible risk to the mother or infant, and after consultation with a healthcare provider.

Lecrolyn (sodium cromoglicate) is a mast cell stabilizer, whereas many alternatives such as olopatadine or ketotifen are antihistamines. Mast cell stabilizers act upstream by preventing mediator release, offering a prophylactic effect, while antihistamines block histamine receptors and provide rapid symptom relief. Choice depends on clinical need and physician preference.

Lecrolyn should be stored at room temperature, preferably below 25 °C, in its original container. Protect the solution from direct light and moisture. Do not freeze. Once opened, follow the manufacturer’s recommended period‑after‑opening (PAO) and discard any remaining product after that time.

Lecrolyn is administered as eye drops. 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. Avoid touching the dropper tip to the eye or any surface to maintain sterility.

Although rare, serious adverse reactions can include severe allergic responses such as anaphylaxis, and corneal ulceration. Patients should seek immediate medical attention if they experience swelling of the face or throat, difficulty breathing, or persistent eye pain and visual changes.

Lecrolyn should not be used by individuals with known hypersensitivity to sodium cromoglicate or any component of the formulation. It is also contraindicated in eyes that are infected, inflamed for reasons other than allergy, or when the solution appears discolored or contains particles.
