What DBL Tobramycin Injection BP is used for
Tobramycin is an antibiotic that belongs to a group of medicines called aminoglycosides (pronounced a-my-noe-GLY-koe-sides).
Tobramycin works by preventing bacteria from growing and thereby killing them. Tobramycin is used for the treatment of serious infections caused by bacteria, including:
•meningitis (infection of the brain)
•septicaemia (infection of the blood)
•respiratory tract infections
•gastrointestinal tract infections
•skin and skin structure infections, including infected burns
•urinary tract infections.
Your doctor may have prescribed tobramycin for another reason.
Ask your doctor if you have any questions about why tobramycin has been prescribed for you.
This medicine is available only with a doctor’s prescription.

Symptoms of an allergic reaction may include:
•shortness of breath, wheezing or difficulty breathing

Tell your doctor if you are breast-feeding or plan to breast-feed.
Tobramycin passes into breast milk and is not recommended for use during breast-feeding. If there is a need for you to be given tobramycin, your doctor will discuss the possible risks and benefits of being given it during breast-feeding.
Tell your doctor or pharmacist if you have or have had any medical conditions, especially the following:
•kidney disease or kidney problems
•muscular disorders (e.g. myasthenia gravis, Parkinson’s disease)
•hearing problems, or if you or your family have a mitochondrial mutation disease, or loss of hearing due to antibiotic medicines; certain mitochondrial mutations may increase your risk of hearing loss with this product.
If you have not told your doctor or pharmacist about any of the above, tell them before you are given tobramycin.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.

These medicines may be affected by tobramycin, or may affect how well it works. You may need different amounts of your medicine, or you may need to take/use different medicines. Your doctor or pharmacist will advise you.
Your doctor and pharmacist may have more information on medicines to be careful with or avoid while receiving tobramycin.
How DBL Tobramycin Injection BP is given
How much is given

How it is given
Tobramycin is given as an injection into a muscle or as a slow injection into a vein (intravenously).
Tobramycin should only be given by a doctor or nurse.
If you are given too much (overdose)
As DBL Tobramycin Injection BP is usually given to you in hospital under the supervision of your doctor, it is very unlikely that you will receive an overdose.
However, if you experience severe side effects tell your doctor or nurse immediately or if you are not already in hospital, immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Emergency at the nearest hospital.
You may need urgent medical attention.
Symptoms of a tobramycin overdose may include the side effects listed below in the ‘Side Effects’ section, but are usually of a more severe nature.
While you are being given DBL Tobramycin Injection BP
Things your doctor should do
Your doctor or nurse should take regular blood and urine samples while you are receiving Tobramycin Injection. This is to ensure that you are receiving the correct dose of tobramycin.
Things you must do
If you are about to be started on any new medicine, remind your doctor, dentist or pharmacist that you are being given this medicine.
Tell any other doctors, dentists, and pharmacists who are treating you that you are being given this medicine.
If you are going to have surgery tell the surgeon or anaesthetist that you are being given this medicine.
It may affect other medicines used during surgery.

Things to be careful of
Be careful driving or operating machinery until you know how DBL Tobramycin Injection BP affects you.
As with other aminoglycoside medicines, DBL Tobramycin Injection BP may cause tiredness, dizziness, or drowsiness in some people.
