What TOBRAMYCIN SUN is used for

TOBRAMYCIN SUN contains an antibacterial agent, tobramycin, which is active against a common lung infection that occurs in patients with cystic fibrosis (CF).

Tobramycin belongs to a class of antibiotics called aminoglycosides. It works by killing or stopping the growth of the bacteria that cause the infection.

Pseudomonas aeruginosa is the bacterium that commonly infects the lung of most cystic fibrosis patients at some stage of their lives. It is one of the most damaging bacteria for people with CF.

Some people do not get this infection until later on in their lives, while others get it very young. If the infection is not properly fought, it will continue to damage your lungs, causing further problems with your breathing.

TOBRAMYCIN SUN solution has been specially formulated for administration by inhalation via a nebuliser and compressor. When you inhale TOBRAMYCIN SUN, the antibiotic can get straight into your lungs to fight against the infection and to improve your breathing.

For best results, please use TOBRAMYCIN SUN as directed by this leaflet.

Although TOBRAMYCIN SUN does not cure your condition, it does help control it.

TOBRAMYCIN SUN is not recommended for use in children younger than 6 years of age, as there have been no studies of its effects in this age group.

Ask your doctor if you have any questions about why TOBRAMYCIN SUN has been prescribed for you. Your doctor may have prescribed TOBRAMYCIN SUN for another reason.

TOBRAMYCIN SUN is only available with a doctor's prescription. It is not addictive.

    If the packaging is damaged or it is past the expiry date, return it to your pharmacist for disposal.

TOBRAMYCIN SUN is not recommended for use in children under 6 years.

Do not give TOBRAMYCIN SUN to a child under 6 years old, unless directed to by the child's doctor or pharmacist.

If you are not sure whether you or your child should start using TOBRAMYCIN SUN, talk to your doctor or pharmacist.

Before you start to use it

Tell your doctor if you are pregnant or intend to become pregnant. TOBRAMYCIN SUN may affect your developing baby if used during pregnancy. Your doctor or pharmacist will discuss the possible risks and benefits of using TOBRAMYCIN SUN during pregnancy.

Tell your doctor if you are breastfeeding or plan to breast-feed. Your baby may absorb this medicine from breast milk and therefore there is a possibility of harm to the baby. Your doctor or pharmacist will discuss the risks and benefits of using TOBRAMYCIN SUN during breast-feeding.

Tell your doctor if you have or have had any medical conditions, especially the following:

  • kidney problems
  • hearing problems, including noises in the ears and dizziness
  • unusual difficulty in breathing with wheezing or coughing, chest tightness
  • trouble with your balance
  • dizzy spells
  • problems with nerve or muscle function
  • muscle weakness that lasts, or becomes worse in time, a symptom mostly related to conditions such as Parkinson’s disease (a condition of the brain affecting movement) or myasthenia (a condition in which the muscles become weak and tire easily).

Tell your doctor if you have allergies to any other medicines or any other substances, such as foods, preservatives or dyes. Your doctor will want to know if you are prone to allergies.

If you are aged 65 years or older, your doctor may perform additional tests to decide if TOBRAMYCIN SUN is right for you.

If you have not told your doctor about any of the above, tell them before you start using TOBRAMYCIN SUN.

Taking other medicines

Tell your doctor if you are using or have recently taken any other medicines, including any vitamin supplements, herbal preparations or any other medicines that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with TOBRAMYCIN SUN or vice versa. These include:

  • diuretics (fluid tablets), especially those that contain frusemide, or ethacrynic acid
  • urea
  • intravenous mannitol
  • tobramycin or another aminoglycoside antibiotic by injection (e.g. amikacin, gentamicin, neomycin, streptomycin).

These medicines may be affected by TOBRAMYCIN SUN, or may affect how well it works. Your doctor or pharmacist will advise you in case you need different amounts of your medicine, or if you need to take different medicines.

Your doctor and pharmacist may have more information on medicines to be careful with or avoid while using TOBRAMYCIN SUN.


How much to use

Inhale TOBRAMYCIN SUN only when prescribed by your doctor.

Do not exceed the recommended dose.

The recommended dose of TOBRAMYCIN SUN is one 300 mg/5 mL ampoule twice daily (every 12 hours) for 28 days.

This is followed by 28 days of not using TOBRAMYCIN SUN. Repeat the 28 day on drug/28 day off drug cycle.

Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.

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

How to use it

TOBRAMYCIN SUN solution is contained in a ready-to-use ampoule and is specifically formulated for inhalation therapy using a PARI LC PLUS reusable nebuliser and a De Vilbiss Pulmo-Aide®air compressor or PARI Pro-Neb System reusable nebuliser.

It is important that your nebuliser and compressor function properly before you start your TOBRAMYCIN SUN therapy.

Breathe normally through the mouthpiece of the nebuliser until all of the TOBRAMYCIN SUN solution is gone and there is no longer any mist being produced. This usually takes approximately 15 minutes. You may sit or stand upright while inhaling TOBRAMYCIN SUN.

If you are not sure how to use a nebuliser, ask your doctor or pharmacist.

Children should only use a nebuliser on medical advice and with the help of an adult.

When to use it

Please check the order of medications with your doctor. If you are taking several different inhaled treatments and performing therapies for cystic fibrosis, you should use TOBRAMYCIN SUN last.

Use TOBRAMYCIN SUN at about the same time every day. Using your medicine at the same time each day will help you remember when to take it.

Inhale TOBRAMYCIN SUN twice daily. Doses should be administered as close to 12 hours apart as possible and not less than 6 hours apart.

How to inhale TOBRAMYCIN SUN

  1. Wash your hands thoroughly with soap and water and fully dry hands.
  2. Just before use, cut or tear open the foil pouch and remove one TOBRAMYCIN SUN ampoule by gently pulling apart one of the attached ampoules at the bottom tabs.
  3. Put the other ampoule(s) back in the foil pouch and keep it in the refrigerator.
  4. Lay out all the pieces of your nebuliser on a clean, dry paper or cloth towel:

a. nebuliser top
b. nebuliser cup
c. inspiratory valve cap
d. mouthpiece with valve
e. tubing

  1. Check that you have the suitable compressor, and tubing to connect the nebuliser and compressor.
  2. Follow the appropriate instructions for use for your type of nebuliser. You must read the leaflet provided with the nebuliser by the manufacturer.
  3. Check that your nebuliser and compressor are working properly according to the manufacturer's instructions before you start to take your medicine.
  4. Remove the nebuliser top from the nebuliser cup by twisting the top anticlockwise and then lifting it.
  5. Place the nebuliser top on the towel and stand the nebuliser cup upright on the towel.
  6. Connect one end of the tubing to the compressor air outlet. Make sure that the tubing fits snugly. Plug the compressor into the electrical outlet.
  7. Open the TOBRAMYCIN SUN ampoule by holding the bottom tab with one hand and twisting off the top with your other hand.
  8. Squeeze all the contents of the ampoule into the nebuliser cup.
  9. Replace the nebuliser top (a), put the mouthpiece (d) and the inspiratory valve cap (c) in place on the nebuliser, and then connect the compressor as indicated in your nebuliser leaflet.
  10. Turn on the compressor. Check that there is a steady mist coming from the mouthpiece. If there is no mist, check all tubing connections and that the compressor is working properly.
  11. Sit or stand in an upright position so that you can breathe normally.
  12. Place the mouthpiece between your teeth and on top of your tongue. Breathe normally, but only through your mouth (you may use a nose clip if your doctor agrees). Try not to block the airflow with your tongue.
  13. Continue until all of the TOBRAMYCIN SUN solution is gone and there is no longer any mist being produced.

It should take about 10-15 minutes to inhale all of the treatment. You may hear a spluttering sound when the nebuliser cup is empty.

How long to use it

Use TOBRAMYCIN SUN twice daily every day for 28 days, followed by a 28 day period without using TOBRAMYCIN SUN. Continue using TOBRAMYCIN SUN in these 28 day on/28 day off cycles for as long as your doctor or pharmacist tells you.

If you have any questions about how long to use TOBRAMYCIN SUN, ask your doctor or pharmacist.

If you forget to use it

If there are at least 6 hours to your next dose, use TOBRAMYCIN SUN and then go back to using your medicine as you would normally. If it is almost time for your next dose, skip the dose you missed and have your next TOBRAMYCIN SUN dose when you are meant to.

Do not have a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure whether to skip the dose, talk to 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)

Immediately telephone your doctor or the Poisons Information Centre for advice (telephone Australia – 13 11 26; New Zealand 0800 POISON / 0800 764 766) or go to the Accident and Emergency Centre at your nearest hospital if you think that you or anyone else may have used too much TOBRAMYCIN SUN.

Do this even if there are no signs of discomfort or poisoning.

Signs of an overdose may include:

  • dizziness
  • ringing in the ears
  • loss of balance
  • hearing problems
  • breathing problems
  • kidney problems
  • difficulty with nerve and muscle function.
