The name of this medicine is Gentamicin Paediatric 20mg/2ml Solution for Injection (called gentamicin in this leaflet). It contains a medicine called gentamicin sulphate. This belongs to a group of antibiotics called ‘aminoglycosides’.

  • Your urinary tract (including your kidneys or bladder)
  • Your chest (including your lungs)
  • Your abdomen (including your gut)
  • Your brain and spinal cord
  • Your blood – this is sometimes called ‘bacteraemia’ or ‘septicaemia’
  • Newborn babies

2. What you need to know before you have gentamicin

Do not have gentamicin if you:

  • are allergic (hypersensitive) to gentamicin, any other antibiotics or to any of the other ingredients of this medicine (see section 6).
    Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat and tongue.
  • have myasthenia gravis. This is a disease that causes muscle weakness.

  • are breast-feeding or are planning to breast-feed.
  • have any muscle weakness problems.
  • are extremely overweight.
  • have kidney problems, are over 65 years of age or the patient is less than 1 year old.

He may check your hearing, your balance, how your kidneys are working and the amount of gentamicin in your blood.
  • know (or think) you have a mitochondrial disease (mutations in the parts of your cells which help make energy); certain mitochondrial diseases may increase your risk of hearing loss with this product.

Other medicines and gentamicin

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription, including herbal medicines.

In particular tell your doctor if you are taking any of the following:

  • Medicines used to thin the blood such as warfarin.
  • Water tablets or injections (diuretics) such as furosemide or etacrynic acid.
  • Amphotericin B (used to treat fungal infections).
  • Cephalosporin antibiotics such as cephaloridine.
  • Ciclosporin (used in organ transplants or for severe skin problems).
  • Neostigmine or pyridostigmine (used to treat myasthenia gravis).
  • Muscle relaxants - sometimes used during operations which need an anaesthetic.
  • Indometacin (used to treat pain or swelling).
  • Bisphosphonates (used to treat osteoporosis).
  • Cisplatin (used to treat some cancers).
  • Botulinum toxin – used to lower the activity of overactive muscles. This is also sometimes used in cosmetic procedures.

These medicines may increase the chances of getting certain side effects. If you are unsure about any of the above, consult your doctor or nurse.
