Optrex Bacterial Conjunctivitis Ointment for Eye Infections

 

You can treat bacterial conjunctivitis effectively with this chloramphenicol-based eye ointment. This medicine contains 1% w/w chloramphenicol, an antibiotic that targets the bacteria causing your eye infection. The ointment format provides longer contact time with the infected area compared to eye drops, making it particularly suitable for overnight treatment.

Each 4g tube delivers targeted treatment directly to your affected eye. The ointment works by stopping bacterial growth and eliminating the infection that causes redness, discharge, and discomfort. You'll find this treatment especially helpful when your symptoms are more severe or when you need sustained medication delivery.

 

How Chloramphenicol Ointment Works Against Bacterial Infections

 

Chloramphenicol belongs to a group of medicines called antibiotics. It works by preventing bacteria from producing proteins they need to survive and multiply. When you apply the ointment to your infected eye, the active ingredient penetrates the affected tissues and begins targeting the bacterial infection at its source.

The ointment base helps the medicine stay in contact with your eye for extended periods. This sustained release means the antibiotic can work continuously, even while you sleep. Most people notice improvement in their symptoms within 48 hours of starting treatment, though you should complete the full course as directed.

 

Who Should Use This Eye Infection Treatment

 

This bacterial conjunctivitis ointment is suitable for adults and children over 2 years old who have confirmed bacterial eye infections. You should only use this medicine when you have symptoms specifically caused by bacteria, not viral or allergic conjunctivitis. Your pharmacist can help you identify whether your symptoms suggest a bacterial infection.

The treatment is particularly appropriate if you experience:

  • Thick, yellow or green discharge from your eye
  • Eyes that are stuck together, especially in the morning
  • Persistent redness and irritation
  • Discomfort that doesn't improve with simple eye washes

You can find additional eye care products to support your overall eye health alongside this targeted antibiotic treatment.

 

Why Choose Ointment Over Eye Drops

 

The ointment formulation offers several advantages for treating bacterial conjunctivitis. Unlike eye drops that can wash away quickly, the ointment stays in place longer, providing sustained antibiotic action. This extended contact time means you typically need fewer applications throughout the day.

You'll find the ointment particularly beneficial for nighttime use, as it won't run out of your eye while you sleep. The thicker consistency also makes it easier to apply accurately, ensuring the medicine reaches the infected area effectively. Many people prefer ointments when dealing with more stubborn infections or when eye drops haven't provided sufficient relief.

 

Storage and Shelf Life Considerations

 

You should store this medicine below 25°C and keep it away from direct sunlight. Once opened, you must use the ointment within 28 days and then dispose of any remaining product safely. Always check the expiry date before use and never share your eye medicine with others, even if they have similar symptoms.

Keep the tube tightly closed when not in use to prevent contamination. The 4g size provides sufficient treatment for a typical course of bacterial conjunctivitis while ensuring you have fresh, effective medicine for each application.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

 

How to Apply Chloramphenicol Eye Ointment

You should wash your hands thoroughly before applying the ointment. Gently pull down your lower eyelid to create a small pocket, then squeeze approximately 1cm of ointment into this space. Close your eye gently and blink a few times to distribute the medicine evenly across the eye surface.

Apply the ointment to the affected eye every 3-4 hours during the day. You can reduce the frequency to twice daily once your symptoms begin to improve, but continue treatment for 48 hours after your eye appears normal. Avoid touching the tube tip to your eye or any other surface to prevent contamination.

Treatment Duration and Frequency Guidelines

You should use this medicine for 5 days, or for 48 hours after your eye returns to normal, whichever is longer. Most bacterial conjunctivitis infections respond within 2-3 days of starting treatment. If your symptoms haven't improved after 2 days, or if they worsen at any time, you should consult your pharmacist or doctor.

Never stop treatment early, even if your eye looks better, as this can lead to the infection returning. If you're treating both eyes, use separate applications to prevent spreading infection from one eye to the other. Always complete the full course of treatment as recommended.
