Lecrolyn Sine is a mast cell stabilizer used to manage ocular allergic conditions.

Allergic conjunctivitis: reduces itching, redness, and tearing caused by allergen exposure. Mast cell‑mediated ocular allergy: prevents mast cell degranulation and histamine release in the eye. Seasonal allergic eye disease: alleviates symptoms during pollen or other seasonal allergen periods.

Adverse reactions are generally mild and related to local ocular tolerance.

Common Side Effects: - Transient burning or stinging sensation after instillation. - Mild eye irritation or foreign‑body feeling. - Temporary blurred vision. - Slight conjunctival redness. - Mild tearing. - Discomfort that resolves within minutes.

Serious or Rare Side Effects: - Severe ocular inflammation or keratitis. - Allergic reaction with swelling or rash. - Corneal ulceration. - Vision loss. - Anaphylactic response (extremely rare).

Use Lecrolyn Sine only under ophthalmic supervision and observe the following precautions.

Do not use if hypersensitivity: discontinue immediately if allergic reaction occurs. Avoid contact lens wear: remove lenses before and for at least 15 minutes after administration. Monitor symptom progression: seek medical advice if condition worsens. Use only as prescribed: do not exceed recommended frequency. Discontinue if severe irritation persists. Store at room temperature: keep in original container, protect from light and moisture.

Lecrolyn Sine may interact with other ocular medications; consider the following.

Major Interactions (Avoid): - Concurrent use with other mast cell stabilisers may increase local irritation. - Combination with topical corticosteroids may mask signs of infection.

Moderate Interactions (Monitor Closely): - Co‑administration with antihistamine eye drops may increase ocular dryness. - Use with preservative‑containing contact lens solutions may heighten irritation. - Systemic antihistamines may reduce overall antiallergic effect.
