3. HOW TO USE CHLORAMPHENICOL 1% W/W EYE OINTMENT

Always use this medicine exactly as your doctor, pharmacist or nurse has told you. Check with your doctor, pharmacist or nurse if you are not sure.

Do not wear contact lenses whilst using Chloramphenicol 1% w/w Eye Ointment. Do not use the product if the seal is broken.

The recommended dose for adults, children and infants of all age groups is as follows:

About 1 cm of ointment to be applied into the affected eye (every three hours or more frequently if required), as directed by your doctor, pharmacist or nurse. You should continue using this ointment for at least 48 hours after your eye has got better.

Dosage adjustment may be necessary in newborn infants because of reduced systemic elimination due to their immature metabolism and the risk of dose-related adverse effects. The maximum duration of treatment is 10-14 days.

Apply your ointment in the following way: 1. Always wash your hands before applying the eye ointment

  1. 2. Remove the cap
  2. 3. Take special care that the nozzle of the tube does not touch your eye, the skin around your eye or your fingers 4. You may use the mirror to help you to see what you are doing
  3. 5. Place the nozzle of the tube close to your eye and gently pull the lower eyelid downwards and look up 6. Squeeze the tube gently and apply about 1 cm of ointment to the space between the lower lid and the eye 7. Blink a few times to ensure the ointment is evenly spread into your eye and close your eye for a moment 8. Where both eyes are to be treated, repeat steps from 3 to 6

If you accidentally use too much or swallow your ointment, contact your doctor although it is unlikely to cause you any harm.

If eye irritation, soreness, swelling, watering or sensitivity to light occur after accidental use in the eye, you should wash out your eye for 15 minutes. If symptoms still persist you should see a doctor, pharmacist or nurse.

If you forget to use Chloramphenicol 1% w/w Eye Ointment

If you stop using Chloramphenicol 1% w/w Eye Ointment

Do not stop using this ointment without talking to your doctor, pharmacist or nurse first.

If your symptoms are not getting better you should tell your doctor immediately. Chloramphenicol may not work against certain types of infections and other types of bacteria or fungi, which are not killed, may take over from the original infection. This may seem as if the original infection has not cleared up or has got worse.
