Murine Hayfever Relief (Sodium Cromoglicate)

Sodium cromoglicate is used to treat ocular allergic conditions by stabilizing mast cells in the eye, preventing release of inflammatory mediators.

• Allergic conjunctivitis: reduces ocular itching, redness, tearing and swelling, improving visual comfort during seasonal allergen exposure.
• Seasonal allergic conjunctivitis: provides relief of eye irritation caused by pollen, grass and weed allergens, helping maintain daily activities.
• Hay‑fever ocular symptoms: alleviates eye itching, burning and watery discharge associated with hay‑fever, supporting overall allergy management.

• Sodium cromoglicate binds to calcium channels on mast cells in the conjunctival tissue, inhibiting calcium influx that triggers degranulation. By stabilizing these cells, it prevents the release of histamine, leukotrienes and other inflammatory mediators, thereby reducing ocular allergic inflammation and symptom generation.

Adverse reactions are generally mild and localized to the eye, but rare serious events have been reported.

Common Side Effects

• Transient eye irritation or stinging after instillation.
• Mild burning sensation.
• Temporary blurred vision.
• Mild conjunctival hyperemia.
• Slight headache.
• Mild eyelid swelling.

Serious or Rare Side Effects

• Severe allergic reaction including anaphylaxis.
• Corneal ulceration or epithelial defect.
• Persistent eye pain or photophobia.
• Vision loss.
• Severe eyelid edema.
• Secondary ocular infection.

Before using Murine Hayfever Relief, consider the following safety measures.

• Pregnancy: safety not established; use only if clearly needed.
• Breastfeeding: unknown; weigh benefits against potential risks.
• Contact lens wearers: remove lenses before instillation and wait before reinserting.
• Known hypersensitivity: avoid if allergic to sodium cromoglicate or any formulation component.
• Ocular infection: defer use until infection has resolved.
• Store at room temperature: keep in original container, protect from light and moisture.

Sodium cromoglicate may interact with other ocular or systemic agents; monitor patients accordingly.

Major Interactions (Avoid)

• Concurrent use of topical ocular anesthetics: may increase irritation.
• Use with other mast cell stabilizers: no additional benefit and may increase exposure.

Moderate Interactions (Monitor Closely)

• Co‑administration with antihistamine eye drops: monitor for additive effect on symptom control.
• Use with topical corticosteroids: watch for increased risk of intra‑ocular pressure changes.
• Systemic antihistamines: may reduce overall allergy burden; adjust ocular therapy as needed.
