The name of your medicine is Genticin Injectable.

Genticin Injectable is used in adults and children to treat bacterial infections such as severe chest infections, urinary tract infections and septicaemia.

  • if you are allergic to a similar medicine containing an aminoglycoside antibiotic
  • if you suffer from myasthenia gravis, a disease causing muscle weakness.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before you are given Genticin Injectable:

  • if you have any problems with your kidneys, liver or hearing
  • if you have, or have a maternal history of mitochondrial mutation disease (a genetic condition) or loss of hearing due to antibiotic medicines, you are advised to inform your doctor or pharmacist before you take an aminoglycoside; certain mitochondrial mutations may increase your risk of hearing loss with this product. Your doctor may recommend genetic testing before administration of Genticin Injectable

  • if you are considered to be significantly overweight

If any of these apply to you or if you are not sure, tell your doctor.

Monitoring during treatment

Your doctor may want to send you for blood tests from time to time to check the levels of gentamicin in your blood. This is because your doctor may need to keep a careful eye on you during your treatment to prevent damage to your ears. If you are over 65 years of age or the patient is under 1 year of age, they may also monitor your hearing, your balance and how your kidneys and liver are working.
