Neomycinum (Neomycin Sulfate)

Neomycin Sulfate, the active ingredient in Neomycinum, is an aminoglycoside antibiotic presented as a sterile ophthalmic solution for ocular use. It treats bacterial conjunctivitis, keratitis and other superficial ocular bacterial infections in patients requiring topical therapy.

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

Neomycinum is an aminoglycoside antibiotic used to manage bacterial infections of the eye surface.

- Bacterial conjunctivitis: reduces bacterial load and alleviates redness, discharge and irritation. - Keratitis: helps eradicate pathogenic bacteria and promotes corneal healing. - Superficial ocular bacterial infections: treats other bacterial involvement of the conjunctiva or cornea, preventing spread and complications.

Neomycinum may cause local ocular reactions and, rarely, systemic toxicity.

Common Side Effects: - Stinging or burning sensation upon instillation. - Redness of the conjunctiva. - Tearing or increased lacrimation. - Transient blurred vision. - Mild ocular irritation. - Temporary eyelid swelling.

Serious or Rare Side Effects: - Allergic contact dermatitis of the eyelid or peri‑ocular skin. - Corneal ulceration or epithelial defect. - Severe eye pain or vision loss. - Systemic absorption leading to nephrotoxicity (very rare). - Ototoxicity in patients with extensive systemic exposure.

Before using Neomycinum, consider the following safety measures.

- Allergy assessment: avoid in patients with known hypersensitivity to neomycin or other aminoglycosides. - Ocular infection monitoring: discontinue if signs of worsening infection or severe irritation appear. - Pregnancy and lactation: use only if the prescriber determines potential benefit outweighs risk. - Contact lens wearers: remove lenses before application and wait before reinserting. - Storage: keep at room temperature: store in original container, protect from light and moisture.

Neomycinum can interact with other medications, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Systemic aminoglycosides: additive risk of nephrotoxicity and ototoxicity. - Loop diuretics: may increase ototoxic potential. - Neuromuscular blocking agents: potential potentiation of neuromuscular blockade.

Moderate Interactions (Monitor Closely): - Topical corticosteroids: may mask signs of infection. - Non‑steroidal anti‑inflammatory eye drops: could increase ocular irritation. - Other topical antibiotics: risk of antagonistic effects or resistance development.
