Xinoxy Eye Ointment 3g – Dual Antibiotic Treatment for Bacterial Eye Infections

Drug Class: Dual Antibiotic Combination | Form: Sterile Ophthalmic Ointment | Prescription Status: Prescription Only (Rx)

What Is Xinoxy Eye Ointment?

Xinoxy Eye Ointment (3g) is a prescription sterile ophthalmic ointment combining two antibiotics — Oxytetracycline Hydrochloride and Polymyxin B Sulfate — to treat superficial bacterial eye infections. Each ingredient works through a completely different antibacterial mechanism, together providing broader coverage against the bacteria most commonly responsible for eye infections than either antibiotic could achieve alone.

Oxytetracycline blocks bacterial protein synthesis while Polymyxin B destroys the outer membrane of gram-negative bacteria — a dual approach that targets both gram-positive and gram-negative organisms simultaneously. As an ointment, Xinoxy maintains prolonged contact with the eye surface, delivering sustained antibacterial action and making it particularly effective for overnight use or when extended coverage is required.

Xinoxy is a prescription-only medicine and must only be used under medical supervision with a confirmed bacterial diagnosis.

What Is Xinoxy Eye Ointment Used For?

Xinoxy Eye Ointment is prescribed for superficial bacterial eye infections caused by susceptible organisms, including:

• Bacterial conjunctivitis (آنکھ آنا) — bacterial infection of the conjunctiva causing redness, discharge, and eye irritation
• Blepharitis — bacterial infection and inflammation of the eyelid margins causing crusting, soreness, and redness
• Styes (انجنی) — infected eyelid glands caused by Staphylococcus aureus bacteria
• Superficial corneal infections — early or mild bacterial involvement of the corneal surface
• Infected corneal abrasions — prevention and treatment of bacterial infection in minor corneal wounds or scratches
• Trachoma — chronic bacterial eye infection caused by Chlamydia trachomatis, for which Oxytetracycline has established clinical activity

Xinoxy treats superficial bacterial infections only. It will not treat viral conjunctivitis, fungal eye infections, or allergic eye conditions. Correct diagnosis is essential before starting treatment.

How Does Xinoxy Eye Ointment Work?

Oxytetracycline Hydrochloride — Protein Synthesis Inhibitor: Oxytetracycline is a broad-spectrum tetracycline antibiotic that enters bacterial cells and binds to the 30S ribosomal subunit — the component bacteria use to manufacture proteins essential for their growth and survival. By blocking this process, Oxytetracycline halts bacterial reproduction and prevents the infection from spreading further. Its broad spectrum covers gram-positive organisms such as Staphylococcus aureus and Streptococcus, gram-negative bacteria, and atypical organisms including Chlamydia trachomatis — the cause of trachoma — making it one of the more versatile antibiotics in ophthalmic use.

Polymyxin B Sulfate — Cell Membrane Disruptor: Polymyxin B is a polypeptide antibiotic that targets the outer cell membrane of gram-negative bacteria. It binds directly to the membrane's phospholipid layer, disrupting its structural integrity and causing the bacterial cell to leak and rapidly die. Polymyxin B provides potent and specific activity against gram-negative organisms including Pseudomonas aeruginosa and Haemophilus influenzae — bacteria that can cause particularly aggressive eye infections and are often resistant to other antibiotic classes.

Combined Effect: Oxytetracycline's broad-spectrum protein synthesis inhibition combined with Polymyxin B's gram-negative membrane destruction creates a complementary dual mechanism — covering the full range of bacteria most commonly responsible for superficial eye infections through two independent pathways, reducing the likelihood of treatment failure due to single-antibiotic resistance.

Dosage and Administration

⚠️ Use exactly as prescribed. Complete the full course even if symptoms improve early. Never touch the tube tip to the eye or any surface. Ointment causes temporary blurring after application — do not drive immediately after use.

How to Apply:

1. Wash hands thoroughly before every application
2. Tilt head back and look upward
3. Gently pull the lower eyelid down to form a small pocket
4. Squeeze approximately 1cm ribbon of ointment into the pocket without allowing the tube tip to touch the eye, eyelid, or any surface
5. Close the eye gently and roll it around to distribute the ointment evenly across the eye surface
6. Blot away any excess ointment from around the eye with a clean tissue
7. Replace the cap firmly immediately after use
8. Temporary blurring for a few minutes after application is normal — wait until vision clears before driving

Active Ingredients

Who Should NOT Use Xinoxy Eye Ointment?

Do not use Xinoxy if you:

• Are allergic to Oxytetracycline, any other tetracycline antibiotic, Polymyxin B, or any ingredient in this product
• Have a viral eye infection — including Herpes simplex keratitis — Xinoxy has no antiviral activity and will not treat viral infections
• Have a fungal eye infection — antibiotics do not treat fungal infections
• Are wearing soft contact lenses — remove before application and do not wear during treatment
• Are pregnant — tetracyclines are generally avoided during pregnancy due to effects on developing fetal bone and teeth

Always consult your doctor before use if you:

• Are breastfeeding — tetracyclines pass into breast milk
• Are using any other eye medications — allow at least 5 minutes between products and apply Xinoxy ointment last
• Have a history of tetracycline hypersensitivity
• Are treating a child under 8 years — systemic tetracyclines are avoided in young children; confirm suitability of topical use with your doctor

Side Effects

Common (mild and temporary):

• Temporary blurring of vision immediately after application — normal with eye ointments, clears within minutes
• Mild stinging or burning sensation on application
• Mild temporary redness or watering of the eye

Serious — Stop Use and Seek Medical Attention Immediately:

• Worsening symptoms despite 48 hours of treatment — increasing redness, pain, or discharge may indicate a resistant organism, incorrect diagnosis, or secondary infection requiring reassessment
• Signs of tetracycline hypersensitivity — increasing irritation, swelling, or rash around the eye after starting treatment
• Severe allergic reaction — swelling of eyelids or face, widespread rash, difficulty breathing (یہ طبی ہنگامی صورتحال ہے)
• Vision changes beyond expected temporary post-application blurring — seek urgent specialist review

If symptoms do not begin to improve within 48 hours of starting Xinoxy, return to your doctor for reassessment without delay.

Frequently Asked Questions

How is Xinoxy different from other antibiotic eye ointments like Polyfax or Cortisporin?

Xinoxy's key distinction is its Oxytetracycline component — a tetracycline antibiotic with activity against a broader range of organisms than many other topical antibiotics, including Chlamydia trachomatis, the cause of trachoma. Polyfax contains Polymyxin B paired with Bacitracin — effective for gram-positive and gram-negative coverage but without tetracycline activity. Cortisporin adds a corticosteroid (Hydrocortisone) for combined antibiotic-steroid treatment. Xinoxy is the appropriate choice when tetracycline-spectrum coverage is required without a steroid — as determined by your prescribing doctor based on your specific diagnosis.

Why must I complete the full course even when my eye looks better?

Symptom improvement — reduced redness, less discharge, less discomfort — occurs when the bacterial population has been significantly reduced but not yet fully eliminated. Stopping antibiotic treatment at this point leaves surviving bacteria in the eye that can regrow, cause a relapse of infection, and potentially develop resistance to Oxytetracycline or Polymyxin B. Completing the full prescribed course ensures the infection is fully cleared and reduces the risk of recurrence and antibiotic resistance development.

Can Xinoxy be used for trachoma?

Yes — Oxytetracycline has well-established clinical activity against Chlamydia trachomatis, the bacterium responsible for trachoma, and tetracycline eye ointments have historically been a standard treatment for this condition. However, trachoma treatment often requires systemic antibiotic therapy alongside topical treatment — particularly in active infection — and must be managed by a doctor. Never self-treat suspected trachoma without proper medical assessment and guidance.

Is Xinoxy safe for use in children?

Topical ophthalmic use of tetracycline-based ointments in children is generally considered lower risk than systemic tetracycline use, as absorption from eye ointment is minimal. However, systemic tetracyclines are avoided in children under 8 years due to effects on bone and tooth development. For any child requiring Xinoxy, always confirm suitability and correct dosing with your prescribing doctor rather than assuming topical use is automatically safe in young children.

Why should I apply Xinoxy ointment last when using multiple eye medications?

 Ointments create a physical barrier on the eye surface that significantly slows the absorption of any subsequently applied drops. If eye drops are applied after the ointment, they sit on top of the ointment layer and cannot properly penetrate to the eye surface where they need to work. Always apply all eye drops first, wait at least 5 to 10 minutes, and apply Xinoxy ointment as the final step to ensure all medications are properly absorbed and effective.
