Mybracin (Dexamethasone, Tobramycin)

Dexamethasone/Tobramycin, the active ingredient in Mybracin, is a corticosteroid/aminoglycoside antibiotic presented as an ophthalmic preparation for ocular use. It combines anti‑inflammatory and antibacterial actions to treat bacterial conjunctivitis, post‑operative ocular inflammation, blepharitis and keratitis in patients as prescribed by an ophthalmologist.

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

Mybracin is used to manage ocular infections and inflammation.

- Bacterial conjunctivitis: reduces bacterial load and associated inflammation. - Post‑operative ocular inflammation: controls swelling and discomfort after eye surgery. - Blepharitis: alleviates eyelid margin inflammation caused by bacterial overgrowth. - Keratitis: treats corneal infection and related inflammatory response.

Adverse reactions may occur with ocular use of Mybracin.

Common Side Effects: - Burning or stinging sensation at the application site. - Transient blurred vision. - Foreign body sensation. - Mild conjunctival hyperemia. - Increased intra‑ocular pressure (monitoring advised). - Temporary tearing.

Serious or Rare Side Effects: - Allergic reactions such as angio‑edema or anaphylaxis. - Severe ocular irritation or corneal ulceration. - Secondary glaucoma due to prolonged steroid exposure. - Systemic aminoglycoside toxicity (rare with topical use). - Development of resistant bacterial strains. - Persistent or worsening infection.

Before using Mybracin, consider the following precautions.

- Pregnancy: consult an ophthalmologist; safety not established. - Breastfeeding: limited data; weigh benefits against potential risks. - Contact lens wear: avoid during treatment to prevent contamination. - Pre‑existing ocular hypertension: monitor intra‑ocular pressure closely. - Concurrent systemic aminoglycosides: avoid to reduce risk of nephro‑ or ototoxicity. - Store at room temperature: keep in the original container, protect from light and moisture.

Mybracin may interact with other medicines.

Major Interactions (Avoid): - Systemic aminoglycosides: additive nephro‑ and ototoxicity. - Topical non‑steroidal anti‑inflammatory drugs (NSAIDs): increased risk of corneal melting. - Live vaccines: immunosuppression may reduce vaccine efficacy.

Moderate Interactions (Monitor Closely): - Cycloplegic agents: may enhance intra‑ocular pressure changes. - Anticholinergic eye drops: possible reduced therapeutic effect. - Systemic corticosteroids: additive systemic steroid effects may occur.
