6. Further information
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’.
Gentamicin is used to treat infections caused by bacteria. This includes infections in:
• Your urinary tract (including your kidneys or bladder)
• Your chest (including your lungs)
• Your blood – this is sometimes called ‘bacteraemia’ or ‘septicaemia’
• Newborn babies
Do not have this medicine if:
• You have Myasthenia Gravis. This is a disease that causes muscle weakness.
• You are allergic (hypersensitive) to gentamicin or to any of the other ingredients of
this medicine (see Section 6: Further Information).
Signs of an allergic reaction include: a rash, swallowing or breathing problems,
swelling of your lips, face, throat and tongue.
Do not have this medicine if any of the above applies to you. If you are not sure, talk
to your doctor or pharmacist before having gentamicin.
Take special care with gentamicin and check with your doctor or pharmacist
before having your medicine if:
• You are pregnant, might become pregnant, or think you may be pregnant.
• You are breast-feeding (see ‘Pregnancy and breast-feeding’ section below)
• You have any muscle weakness problems
• You are extremely overweight
• You have kidney problems, are over 65 years of age or the patient is less than
1 year old. This is because your doctor will need to keep a careful eye on you
during your treatment, to prevent damage to your ears. He may check your
hearing, your balance, how your kidneys are working and the amount of
gentamicin in your blood.
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist
before having gentamicin.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken 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 (see
Section 4: Possible side effects). If you are unsure about any of the above, consult
your doctor
Pregnancy and breast-feeding
Talk to your doctor before having this medicine if:
• You are pregnant, think you may be pregnant or plan to get pregnant. Gentamicin
should not normally be used during pregnancy.
• You are breast-feeding or planning to breast-feed
Gentamicin contains sodium. It contains 17.30mg sodium per vial.
Gentamicin is always given to you by a doctor or nurse. This is because it needs to
be given as an injection.
Having this medicine
Your doctor will decide how much to give you, depending on your weight. The correct
dose also depends on the type of infection and any other illnesses you may have.
Blood samples will be taken by your doctor or nurse to check the dose is right for you.

How much gentamicin is given
• The usual daily dose in adults is 3-5mg for each kg of body weight
• This is split into doses given every 6-8 hours
• This dose may be increased or decreased by your doctor depending on your illness
• If you have kidney problems your doctor may give you a lower dose
• Elderly people should be closely monitored when having this medicine
Children (aged 1 year and above) and adolescents
• The usual daily dose is 3-6mg for each kg of body weight
• This is given either as 1 single dose (preferred) or split into 2 separate doses
Babies (aged 4 weeks to 1 year)
• The usual daily dose is 4.5 to 7.5mg for each kg of body weight
• This is given either as 1 single dose (preferred) or split into 2 separate doses
New born babies (up to 4 weeks):
• The usual daily dose is 4 to 7mg for each kg of body weight
• This is given in 1 single dose
If you have more gentamicin than you should
It is most unlikely that you will be given too much medicine by the doctor or nurse.
Your doctor or nurse will be checking your progress and checking the medicine that
you are given. Ask if you are not sure why you are getting a dose of medicine.
If you miss a dose of gentamicin
Gentamicin will be given to you by a doctor or nurse. It is most unlikely that you will
not be given the medicine as it has been prescribed. If you think that you may have
missed a dose then talk to your nurse or doctor.
If you stop having gentamicin
It is important that the course of treatment your doctor has prescribed is finished.
You may start to feel better but it is important to continue your treatment until the
doctor advises. If you stop, your infection may get worse again.
Like all medicines, gentamicin can cause side effects, although not everybody gets them.
Tell your doctor or nurse as soon as possible if any of the following side
effects happen:
• It becomes difficult keeping your balance, you feel dizzy or your hearing becomes
poor. Gentamicin can sometimes damage the ear. This is more likely to happen if
your kidneys do not work very well.
• If you notice anything unusual when you pass water, such as any sign of blood in
your water (urine) or you find you are passing less water than is normal for you.
This may mean you have kidney problems.
• If you have unusual difficulty in moving which has not happened before, feel weak
or unusually tired or have any breathing difficulties that have not happened before.
This may mean you have nerve or muscle problems.
• You get swelling of the hands, feet, ankles, face, lips or throat which may cause
difficulty in swallowing or breathing. You could also notice an itchy, lumpy rash
(hives) or nettle rash (urticaria).
This may mean you are having an allergic reaction to gentamicin
If you notice any of the above, talk to your doctor or nurse as soon as possible.
