Lecrolyn Sine

Sodium Cromoglicate, the active ingredient in Lecrolyn Sine, is a mast cell stabilizer presented as a sterile ophthalmic solution for ocular use. It treats allergic conjunctivitis and ocular allergy in patients who experience eye irritation due to allergens.

GNH USA supplies Lecrolyn Sine as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Sodium Cromoglicate is used to manage ocular allergic conditions by stabilising mast cells and preventing inflammatory mediator release.

Allergic conjunctivitis: reduces itching, redness and swelling of the eyes. Ocular allergy: prevents symptoms such as tearing and burning caused by allergen exposure. Seasonal allergic conjunctivitis: provides relief during pollen seasons.

Adverse reactions may occur with ocular use of sodium cromoglicate.

Common Side Effects: - Stinging or burning sensation upon instillation - Transient blurred vision - Mild eye irritation or itching - Temporary conjunctival hyperemia - Slight discharge or tearing - Mild foreign‑body sensation

Serious or Rare Side Effects: - Allergic reaction (e.g., eyelid swelling, rash) - Severe eye pain or photophobia - Vision loss or sudden visual disturbance - Corneal ulcer or keratitis - Persistent redness or inflammation - Anaphylaxis (rare)

Before using Lecrolyn Sine, consider the following precautions.

Avoid use in patients with known hypersensitivity to sodium cromoglicate or formulation excipients. Do not apply if the eye is infected or has a corneal ulcer without physician guidance. Monitor for signs of ocular irritation; discontinue if severe discomfort persists. Contact lenses should be removed before instillation and reinserted after the solution has been absorbed. Store at room temperature: keep in the original container, protect from light and moisture.

Sodium cromoglicate may interact with other ocular medications; review the following.

Major Interactions (Avoid): - Concurrent use with preservative‑containing contact lens solutions may increase ocular irritation. - Simultaneous administration of topical ocular anesthetics can mask adverse reactions.

Moderate Interactions (Monitor Closely): - Use with topical antihistamines may reduce the stabilising effect of sodium cromoglicate. - Co‑administration of corticosteroid eye drops may increase risk of infection. - Systemic antihistamines may exacerbate dry‑eye symptoms when combined with ocular therapy.
