Using other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including other eye drops or ointments, and any other medicines that you get without a prescription from a pharmacy, supermarket or health food shop.
Some medicines and TOBREX® Eye Drops may interfere with each other. These include:
- topical beta lactam type antibiotics
These medicines may be affected by TOBREX® Eye Drops, or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor or pharmacist has more information on medicines to be careful with or avoid while using this medicine.
How to use TOBREX® Eye Drops
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you are being changed from one medicine to another, follow your doctor’s instructions carefully as to when to stop the medicine and when to start the new eye drops.
If you do not understand the instructions on the carton / bottle, ask your doctor or pharmacist for help.
How much to use
Use TOBREX® Eye Drops only when prescribed by your doctor.
Theusual dose for adults will depend on the type and severity of the infection that is being treated. For very severe infections your doctor may recommend that you apply 2 drops in the affected eye(s) every hour; in mild to moderate infections this will usually be reduced to a 1 - 2 drops in the affected eye(s) every four hours.
Your doctor will tell you how much you need to use each day. These dosing instructions will be printed on the label your pharmacist puts on the bottle or carton.
How to use it
It is important to use TOBREX® Eye Drops exactly as your doctor or pharmacist has told you. If you use it less often than you should, it may not work as well and the eye problem may not improve. Using it more often than you should may not improve the eye problem any faster and may cause increased side effects.
Follow these steps to use the eye drops:
- Wash your hands thoroughly with soap and water.
- Immediately before using a bottle for the first time, break the safety seal around the neck area and throw the loose plastic ring away.
- Remove the cap from the bottle.
- Hold the bottle upside down in one hand between your thumb and middle finger (see Diagram 1).
- While tilting your head back, gently pull down the lower eyelid of your eye to form a pouch / pocket.
- Place the tip of the bottle close to your eye. Do not let it touch your eye.
- Release one drop into the pouch / pocket formed between your eye and eyelid by gently tapping or pressing the base of the bottle with your forefinger (see Diagrams 2 and 3).
- Close your eye. Do not blink or rub your eye.
- While your eye is closed, place your index finger against the inside corner of your eye and press against your nose for about two minutes. This will help to stop the medicine from draining through the tear duct to the nose and throat, from where it can be absorbed into other parts of your body. This will also reduce the unpleasant taste sensation that some people experience when using these drops.
- If necessary, repeat the above steps for the other eye.
- Your eyelids can only hold less than one drop at a time, so it is normal for a small amount of the eye drop to spill onto your cheek. You should wipe away any spillage with a tissue.
- Replace the cap on the bottle, closing it tightly.
- Wash your hands again with soap and water to remove any residue.
You may feel a slight burning sensation in the eye shortly after using TOBREX® Eye Drops. If this persists, or is very uncomfortable, contact your doctor or pharmacist.
Be careful not to touch the tip of the bottle against your fingers or the eye, or anything else. This will help prevent the eye drops becoming dirty or contaminated.
If you have trouble knowing whether you have placed your drops correctly, you may want to store them in the fridge. Some people find it easier to feel the drops if they are cold.
After using TOBREX® Eye Drops, wait at least 5 minutes before putting any other eye drops in your eye(s).
Wait 15 minutes before replacing your contact lenses.
When to use it
Use TOBREX® Eye Drops, at about the same time every day unless your doctor tells you otherwise. Using your eye drops at the same time each day will have the best effect on your eye infection. It will also help you remember when to use it.
How long to use it
Keep using TOBREX® Eye Drops for the full time of treatment, even if you begin to feel better after a few days. If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.
If you are unsure about when or how to stop using TOBREX® Eye Drops you should talk to your doctor or pharmacist.
If you forget to use it
If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to.
Otherwise, use the eye drops as soon as you remember, and then go back to using them as you would normally.
Do not use a double dose to make up for the eye drops that you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to use your medicine, ask your pharmacist for some hints.
If you use too much (overdose)
If you accidentally put too many eye drops in your eye(s) immediately rinse your eye(s) with lukewarm water.
If you think that you or someone else has swallowed any or all of the contents of TOBREX® Eye Drops, or used too many eye drops, immediately telephone your doctor or the Poisons Information Centre.
In Australia call 13 11 26; in New Zealand call 0800 POISON or 0800 764 766 for advice or go to Accident & Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning.
While you are using TOBREX®Eye Drops
Things you must do
If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.
If you are about to start taking any new medicine, tell your doctor and pharmacist that you are taking TOBREX® Eye Drops.
Tell all the doctors, dentists and pharmacists who are treating you that you are using TOBREX® Eye Drops.
Tell your doctor if, for any reason, you have not used TOBREX ® Eye Drops exactly as prescribed . Otherwise your doctor may think that it was not effective and change the treatment unnecessarily.
If you become pregnant while using TOBREX® Eye Drops, tell your doctor.
Things you must not do
Do not let children handle TOBREX® Eye Drops
Do not use TOBREX® Eye Drops to treat any other complaints unless your doctor tells you to.
Do not give TOBREX® Eye Drops to anyone else, even if they have the same condition as you.
Do not stop using TOBREX® Eye Drops or lower the dosage because you are feeling better, unless advised by your doctor. If you do not complete the full course prescribed by your doctor, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or it may return.
Things to be careful of
Be careful driving or operating machinery until you know how TOBREX® Eye Drops affect you and your vision. As with any eye medicine, temporary blurred vision or other visual disturbances may affect the ability to drive or use machines. If blurred vision occurs at instillation, wait until your vision is clear before driving or using machinery.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using TOBREX ®Eye Drops.
This medicine helps most people with eye infections, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Do not be alarmed by the following list of possible side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
- Eye irritation or feeling of having something in the eye
- Inflammation of the cornea (clear front portion of your eye) (punctate keratitis)
- swollen/itchy eyelids
- eye redness

- skin rash
- swelling of the face, hands or feet
- wheezing, difficulty in breathing
- severe and sudden onset of pinkish, itchy swellings on the skin, also called hives or nettlerash

Tell your doctor or pharmacist if you notice anything that is making you feel unwell. Other side effects not listed above may also occur in some people.
After using TOBREX® Eye Drops
Store TOBREX® Eye Drops in a cool dry place where the temperature stays below 25°C. It is not necessary to store TOBREX® Eye Drops in the refrigerator but it is acceptable if you prefer to instill cold drops. Do not freeze.
Do not store TOBREX® Eye Drops or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.
Do not leave the cap off the bottle for any length of time to avoid contaminating the eye drops.
Keep it where children can not reach it. A locked cupboard at least one-and a half meters above the ground is a good place to store medicines.
Write the date on the bottle when you open the eye drops and throw out any remaining drops after four weeks. TOBREX® Eye Drops contains a preservative which helps prevent germs growing in the solution for the first four weeks after opening the bottle. After this time there is a greater risk that the solution may become contaminated and cause an eye infection. A new bottle should be opened.
If your doctor tells you to stop using TOBREX® Eye Drops or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.
