Before using Lecrolyn, consider the following safety measures.

Pregnancy: safety not established; use only if clearly needed. Breastfeeding: unknown; weigh potential benefits against risks. Contact lens wearers: remove lenses before instillation and wait at least 15 minutes before reinserting. Concomitant ocular medications: administer other drops at least five minutes apart to avoid dilution. Allergy to sodium cromoglicate: contraindicated. Store at room temperature: keep in the original container, protect from light and moisture.

Lecrolyn may interact with other ophthalmic agents; monitor patients accordingly.

Major Interactions (Avoid): - Concurrent use with ophthalmic anesthetics may increase corneal toxicity. - Systemic mast cell stabilisers may produce additive effects and are not recommended. - Topical corticosteroids can mask signs of infection when used together.

Moderate Interactions (Monitor Closely): - Antihistamine eye drops may reduce the efficacy of sodium cromoglicate. - Non‑steroidal anti‑inflammatory eye drops can increase ocular irritation when combined. - Preservative‑containing solutions may exacerbate local sensitivity.
