What Ciloquin is used for

Ciloquin is used to treat certain types of ear infections caused by bacteria. Your doctor will usually prescribe this medicine because you have a middle ear infection.

Ciloquin contains ciprofloxacin hydrochloride and is an antibiotic that belongs to a group of medicines called fluoroquinolones. This antibiotic works by killing the bacteria that are causing your infection.

Ciloquin will not work against infections caused by viruses, such as colds or the flu, or infections caused by fungus.

Before prescribing Ciloquin, the doctor will have examined your ear(s) and decided that Ciloquin is the right medicine for you.

Your doctor may have prescribed Ciloquin for another reason.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Ciloquin Ear Drops are only available on a doctor’s prescription.

Use in children

Do not use Ciloquin Ear Drops in children under 12 months of age. The safety and effectiveness of Ciloquin Ear Drops in this age group has not been established.

If you are not sure whether you should start using Ciloquin, talk to your doctor.

Before you start to use it

Tell your doctor if you have had an allergy to any other medicines or any other substances, such as foods, preservatives or dyes.

Tell your doctor if you have or have had any medical conditions.

Tell your doctor if you are pregnant or plan to become pregnant. Your doctor will discuss the possible risks and benefits of using Ciloquin during pregnancy.

Tell your doctor if you are breastfeeding. Your doctor will discuss the possible risks and benefits of using Ciloquin when you are breastfeeding.

If you have not told your doctor about any of the above, tell him/ her before you use Ciloquin.

Using or taking other medicines

Tell your doctor or pharmacist if you are using or taking any other medicines, including other ear drops and any other medicines that you get without a prescription from a pharmacy, supermarket or health food shop. Some medicines and ciprofloxacin may interfere with each other.

Tell your doctor if you are taking any of the following:

  • medicines to thin your blood e.g. warfarin
  • medicines to prevent tissue rejection e.g. cyclosporin
  • theophylline for asthma or breathing problems
  • caffeine for the treatment of migraines.

Your doctor and pharmacist will have more information on medicines to be careful with or avoid while using this medicine.

How to use Ciloquin

Carefully follow all directions given to you by your doctor and pharmacist. 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 this medicine and when to start the new ear drops.

If you do not understand the instructions on the carton / bottle, ask your doctor or pharmacist for help.

How much to use

The usual dose in adults and children (1 month and older) is five drops of Ciloquin in the affected ear(s), twice each day for nine days.

Your doctor will tell you how many drops 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 Ciloquin exactly as your doctor or pharmacist has told you. If you use the drops less often than your doctor has advised, your medicine may not work as well and your ear infection may not improve. If you use the drops more often than your doctor has advised, your ear infection may not improve any faster and this may lead to increased side effects.

Before opening the bottle for the first time, make sure the safety seal joining the cap to the bottle is not broken. If it is, do not use the bottle and return it to your pharmacist.

To open a new bottle of Ciloquin, break the safety seal by removing the cap from the bottle. Remove the lower portion of the safety seal and discard.

Follow these steps to use the ear drops:

  1. Wash your hands thoroughly with soap and water.
  2. Shake the bottle.
  3. Remove the cap from the bottle.
  4. Hold the bottle upside down in one hand between your thumb and middle finger (see Diagram 1).

  1. Tilt your head to one side so that the affected ear is facing up. This may be easier in the sitting or lying down position (see Diagram 2).

  1. Place the dropper tip close to, but not touching, your ear and gently tap or press the base of the bottle with your forefinger to release drops (see Diagram 3).

  1. Hold the head in the same position for about one minute. This will help the drops to reach deeper into the ear.
  2. Repeat the above steps for the other ear if necessary.
  3. Place the cap on the bottle and close it tightly.
  4. Wash your hands again with soap and water to remove any residue.

There might be a slightly unpleasant feeling as the drops flow all the way into the ear. If this persists, or is very uncomfortable, contact your doctor or pharmacist.

Be careful not to touch the dropper tip against your fingers or the ear, or anything else. This will help prevent the ear drops becoming dirty or contaminated.

When to use it

Use Ciloquin, at about the same time every day unless your doctor tells you otherwise. Using your ear drops at the same time each day will have the best effect on your ear infection. It will also help you remember when to use it.

How long to use it

Continue using your medicine for as long as your doctor tells you.

As Ciloquin Ear Drops start to kill the bacteria that are causing the infection in your ear(s) you will start to feel better. However, it is very important that you continue to use Ciloquin Ear Drops for the full treatment period advised by your doctor to ensure that the infection does not return.

If you are unsure about when to stop using Ciloquin Ear Drops you should talk to your doctor or pharmacist.

If you forget to use it

If it is almost time for your next drop(s), skip the drop(s) you missed and use your next drop(s) when you are meant to.

Otherwise, use the drop(s) 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 drop(s) 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 Ciloquin drops in your ear(s) immediately rinse your ear(s) with warm water.

If you think that you or someone else has swallowed any, or all, of the contents of Ciloquin, or used too many drops, immediately telephone your doctor or the Poisons Information Centre on 13 11 26 for advice or go to Accident and Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning.

While you are using Ciloquin

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.

Tell your doctor if, for any reason, you have not used Ciloquin Ear Drops exactly as prescribed. Otherwise your doctor may think that the ear drops were not effective and change the treatment unnecessarily.

If you become pregnant while you are using this medicine, tell your doctor immediately,

If you are about to be started on any new medicine, remind your doctor or pharmacist that you are using Ciloquin Ear Drops.

Tell all the doctors, dentists and pharmacists who are treating you that you are using Ciloquin.

Things you must not do

Do not use Ciloquin Ear Drops to treat other complaints unless your doctor tells you to.

Do not give this medicine to anyone else, even if they appear to have the same condition as you.

Do not stop using Ciloquin Ear Drops or lower the dose without first asking your doctor.

Do not let children handle Ciloquin Ear Drops.

Things to be careful of

Be careful driving or operating machinery until you know how Ciloquin affects you and your hearing. This medicine may cause dizziness or light-headedness in some people. Make sure you know how you react to the ear drops before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed. If you drink alcohol, dizziness or light-headedness may by worse.

Be careful of sun exposure. These medicines cause some people to sunburn more readily.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using Ciloquin.

This medicine helps most people with middle ear infection, 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:

  • bad taste in the mouth following the use of Ciloquin
  • ear stinging or discomfort following use of Ciloquin
  • headache
  • ear pain
  • vertigo and transient dizziness
  • ear itching (pruritus)
  • inflammation, itching and scaling of the outer ear (fungus infection of the ear; otomycosis)
  • fever
  • weeping ear
  • ear congestion.

These are the more common side effects of your medicine. They are usually mild and short-lived.

If any of the following happen, stop using Ciloquin and tell your doctor immediately or go to Accident and Emergency at your nearest hospital:

  • 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 nettle rash

These hypersensitivity reactions can be very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.

If you are over 65 years of age and taking inflammatory inhibiting medicines similar to cortisone, you have a higher risk of getting tendon problems during treatment with Ciloquin Ear Drops. If this occurs, stop treatment and immediately consult your doctor.

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 Ciloquin


Keep Ciloquin Ear Drops in a cool dry place, where the temperature stays below 25°C. Do not refrigerate or freeze. Cold ear drops may hurt your ear(s) or cause temporary dizziness.

Protect from light.

Do not store Ciloquin Ear Drops or any other medicine in the car, the bathroom or any other warm, damp place. Heat and dampness can destroy some medicines.

Do not carry the ear drops in the pockets of your clothes.

Do not leave the top off the bottle for any length of time, to avoid contaminating the ear drops.

Do not use the ear drops if the solution is discoloured brown.

Keep it out of the sight and reach of children.


Write the date on the bottle when you open the ear drops and throw out any remaining solution after four weeks. Ciloquin 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 drops may become contaminated and cause an ear infection. A new bottle should be opened.

If your doctor tells you to stop using Ciloquin or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.
