Lecrolyn

Sodium Cromoglicate, the active ingredient in Lecrolyn, is a mast cell stabilizer presented as an ophthalmic solution for ocular use. It is indicated for patients experiencing seasonal or perennial eye allergy symptoms and is formulated for convenient drop administration. It is employed to manage allergic conjunctivitis and related ocular itching in patients requiring topical antiallergic therapy.

Lecrolyn, a mast cell stabilizer, is used to treat ocular allergic conditions by preventing mediator release.

Allergic conjunctivitis: reduces redness, swelling and itching associated with allergic eye inflammation. Ocular itching due to allergy: provides rapid relief of itch sensation in the eyes. Seasonal allergic conjunctivitis: controls symptoms during pollen seasons by stabilizing ocular mast cells.

Topical ocular administration of Lecrolyn may be associated with the following adverse reactions.

Common Side Effects: - Burning or stinging sensation upon instillation. - Transient blurred vision or mild eye irritation. - Temporary increase in tear production.

Serious or Rare Side Effects: - Allergic contact dermatitis of the eyelid or conjunctiva. - Corneal ulcer or severe keratitis. - Sudden loss of vision or severe eye pain requiring immediate medical attention.

When using Lecrolyn, consider the following precautions to ensure safe and effective therapy.

Hypersensitivity: Do not use if known allergy to sodium cromoglicate or any excipients. Contact lenses: Remove contact lenses before instillation and wait at least 15 minutes before reinserting. Concurrent ocular infection: Avoid use in the presence of active bacterial, viral or fungal eye infection unless directed by a clinician. Pregnancy and lactation: Use only if the benefit outweighs potential risk, as safety data are limited. Store at room temperature: keep in original container, protect from light and moisture.

Lecrolyn may interact with other ophthalmic or systemic agents; the following interactions have been reported.

Major Interactions (Avoid): - Concurrent use with topical ocular anesthetics may increase corneal toxicity.

Moderate Interactions (Monitor Closely): - Use with other mast cell stabilizer eye drops may increase local irritation. - Combination with topical corticosteroids may raise risk of ocular infection. - Co‑administration with antihistamine eye drops may reduce the efficacy of either agent. - Systemic antihistamines may have additive antiallergic effect, requiring monitoring.
