Do not have this medicine if any of the above applies to you. If you are not sure, talk to your doctor or nurse before having gentamicin.

Talk to your doctor or nurse before having gentamicin if you:

• are pregnant, think you may be pregnant or are planning to have a baby.
• are breast-feeding or are planning to breast-feed.
• have any muscle weakness problems.
• are extremely overweight (obese).

• 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, pharmacist or nurse before you take or are given an aminoglycoside; certain mitochondrial mutations may increase your risk of hearing loss with this product. Your doctor may recommend genetic testing before administration of gentamicin.

Your doctor will need to monitor you before, during and shortly after your treatment. Your doctor may check your hearing, balance, how your kidneys are working and the amount of gentamicin in your blood. This is to prevent damage to your ears and/or kidneys and is particularly important if you have kidney problems, are obese, suffer from cystic fibrosis or are over 65 years of age, or the patient is less than 1 year old.

If you are not sure if any of the above applies to you, talk to your doctor or nurse before having gentamicin.

Talk to your doctor or nurse if you experience severe diarrhoea.

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. This is because gentamicin can affect the way some other medicines work. Also, some medicines can affect the way gentamicin works. 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.

Ask your doctor or nurse for advice before having this medicine if you are:

• pregnant, think you may be pregnant or are planning to have a baby. Gentamicin should not normally be used during pregnancy.
• breast-feeding or are planning to breast-feed.

You should not receive gentamicin if these blood tests cannot be performed.

You may also need tests to check your hearing and balance.
