Tobramycin + dexamethasone - ophthalmic

Patient Medicine Information
Why do I need this medicine?
Tobramycin and Dexamethasone are combined in this medicine.

This medicine is used to treat and prevent inflammation and infections of the eyes.
How do I use this medicine?
Instil Tobramycin + Dexamethasone exactly as directed by your doctor or according to the instructions on the label. Do not use more or less than instructed by your doctor.

This medicine is available as an eye drop suspension or eye ointment.

To use the eye drop suspension:
  1. Wash your hands thoroughly with soap and water before using the eye drops.
  2. Shake the bottle well before using.
  3. Tilt your head slightly backwards. With the index finger, pull the lower eyelid away from the eye to form a pouch. Look upward and instil the required number of drops inside the lower eyelid.
  4. Close your eyes. Using your index finger, apply gentle pressure against the corner of your eye (by the nose) for at least 1 minute. This will help keep the medicine in your eye.
  5. Wipe any excess liquid from your face with a clean tissue.
  6. Replace and tighten the cap of the bottle.
To use the eye ointment:
  1. Wash and dry your hands before applying the ointment.
  2. With your index finger, pull the lower eyelid down the eye to form a pouch.
  3. Hold the tube with your other hand and place it as near to your eyelid as possible without touching it. Squeeze a thin strip of ointment (about 1/2 inch) into the pouch.
  4. Gently close your eyes and keep them closed for 1 to 2 minutes.
  5. Wipe any excess ointment from the eyelids and lashes with a clean tissue. With another clean tissue, wipe the tip of the tube clean.
  6. Replace and tighten the cap of the tube.
  7. Wash your hands to remove any medication.
Do not allow the tip of the dropper of this medicine to touch your eyes, eyelids or any other surface. Recap the eye drop immediately after use. If the eye drop becomes contaminated, it could cause an infection in your eyes.

If you have been given any other eye drops or medicines to be used together with this medicine, wait for at least 5 minutes before using the other medicine. Eye ointments should be used last.

Do not share your eye drop or eye ointment with anyone else.

Do not wear contact lenses during treatment with Tobramycin + Dexamethasone.

If your doctor allowed you to wear contact lenses while being treated with the eye drops or eye ointment, remove your contact lenses before using this medicine and wait for at least 15 minutes before reinserting your lenses since some brands of this medicine contain benzalkonium chloride as preservative which may discolour soft contact lenses and cause eye irritation.

The dose of this medicine will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on the type and severity of your infection.

You must complete the entire course of this medicine. If you don't, the infection will not be properly controlled.
What should I do if I have forgotten to use this medicine?
Instil the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.

DO NOT double a dose under any circumstances.

If you often forget to use this medicine, let your doctor and pharmacist know.
