1. What Amoxicillin is and what it is used for

The name of your medicine is Amoxicillin Powder for Solution for Injection. The vials contain a medicine called amoxicillin sodium. This belongs to a group of medicines called ‘penicillin’.

What Amoxicillin is used for

Amoxicillin is used to treat infections caused by bacteria in different parts of the body.

Amoxicillin Powder for Solution for Injection is usually used for urgent treatment of severe infection or if patients cannot take Amoxicillin by mouth.

2. What you need to know before you are given Amoxicillin Injection
You should not be given Amoxicillin
  • if you are allergic to amoxicillin or penicillin. There are no other ingredients in this medicine (see section 6)
  • if you have had an allergic reaction to any antibiotic. This can include a skin rash or swelling of the face or throat
  • if you have previously been told that your infection cannot be treated with amoxicillin or ampicillin
  • Methotrexate (used to treat cancer and severe psoriasis), penicillins may reduce the excretion of methotrexate causing a potential increase in side effects
  • Probenecid (used to treat gout), concomitant use of probenecid may reduce the excretion of amoxicillin and is not recommended.

You should not be given Amoxicillin if any of the above applies to you.

If you are not sure speak to your doctor, nurse or pharmacist.

Warnings and precautions

Talk to you doctor, pharmacist or nurse before you are given Amoxicillin if you:

  • have glandular fever (fever, sore throat, swollen glands and extreme tiredness)
  • have kidney problems
  • are not urinating regularly
  • have a problem with your heart
  • have undiagnosed sore throat (pharyngitis) or a type of cancer known as lymphatic lymphoma, which affects white blood cells
  • have HIV.

If you are not sure if any of the above apply to you, talk to your doctor, pharmacist or nurse before taking Amoxicillin.

Blood and urine tests

If you are having:

  • Urine tests (glucose) or blood tests for liver function
  • Oestriol tests (used during pregnancy to check the baby is developing normally).

Tell your doctor, pharmacist or nurse that you are taking Amoxicillin. This is because Amoxicillin can affect the results of these tests.

Children

Care should be taken in newborns and young infants as there is the chance of higher levels of amoxicillin in the blood.

Other medicines and Amoxicillin

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

  • If you are taking allopurinol (used for gout) with Amoxicillin, it may be more likely that you will have an allergic skin reaction
  • If you are taking probenecid (used for gout), your doctor may decide to adjust your dose of Amoxicillin
  • If you are taking medicines to help stop blood clots (such as warfarin), you may need extra blood tests
  • If you are taking other antibiotics (such as tetracycline) Amoxicillin may be less effective
  • If you are taking methotrexate (used for the treatment of cancer and severe psoriasis) Amoxicillin may cause an increase in side effects.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before you are given this medicine.

Driving and using machines

Amoxicillin can have side effects and the symptoms (such as allergic reactions, dizziness and convulsions) may make you unfit to drive.

Do not drive or operate machinery unless you are feeling well.

Important information about some of the ingredients of Amoxicillin

Amoxicillin 250mg powder for solution for injection contains 14.9mg of sodium.

Amoxicillin 500mg powder for solution for injection contains 29.7mg of sodium.

3. How Amoxicillin is given

You will never give yourself this medicine. A qualified person, like a doctor or a nurse, will give you this medicine.

  • Your medicine will be given to you by injection into a muscle (intramuscularly) or into a vein (intravenously) or as an infusion into a vein
  • Your doctor will decide how much you need each day and how often the injections should be given
  • Make sure you drink plenty of fluids while having Amoxicillin.

To treat infections the usual doses are as follows:

Children up to 40kg

  • Most infections: 20mg to 200mg for every kilogram of body weight in divided doses throughout the day
  • Lyme disease (an infection spread by parasites called ticks): isolated erythema migrans (early stage – red or pink circular rash) 25mg to 50mg for every kilogram of body weight in divided doses throughout the day; systemic manifestations (late stage – for more serious symptoms or when the disease spreads around your body) 100mg for every kilogram of body weight in divided doses throughout the day
  • Intravenous maximum single dose: 50mg for every kilogram of body weight
  • Intramuscular maximum daily dose: 120mg for every kilogram of body weight as 2 to 6 equally divided doses.

Adults, elderly patients and children weighing 40kg or more

  • Usual daily dosage: 750mg to 6g administered in divided doses
  • Intravenous maximum daily dose: 12g per day
  • Intravenous maximum single dose: 2g by infusion or 1 g by bolus injection
  • Intramuscular maximum daily dose: 4g per day
  • Intramuscular maximum single dose: 1g
  • Lyme disease (an infection spread by parasites called ticks): isolated erythema migrans (early stage – red or pink circular rash) 4 g per day; systemic manifestations (late stage - for more serious symptoms or when the disease spreads around your body) 6g per day.

Patients with kidney problems

If you have kidney problems the dose might be lower than the usual dose. Amoxicillin is removed by dialysis (artificial filtration and purification of the blood). Therefore, patients receiving dialysis may require another dose of Amoxicillin at the end of their dialysis session.

If you are given more Amoxicillin than you should

This medicine is given to you by a doctor or a nurse. It is unlikely that you will be given too much, but if you think you have been given too much Amoxicillin, tell your doctor or nurse immediately. Signs might be an upset stomach (feeling sick, being sick or diarrhoea) or crystals in the urine, which may be seen as cloudy urine or problems urinating.

The doctor will assess your condition and decide how to treat an overdose.

If you think you have missed a dose of Amoxicillin

If you think that a dose of Amoxicillin has been missed, speak to your doctor or nurse.

How long will you need to take Amoxicillin for?

You will not normally be given Amoxicillin for more than 2 weeks without the doctor reviewing your treatment.

Thrush (a yeast infection of moist areas of the body which can cause soreness, itching and white discharge) may develop if Amoxicillin is used for a long time. If this occurs, tell your doctor, pharmacist or nurse.

If you are given Amoxicillin for a long time, your doctor may perform additional tests to check your kidneys, liver and blood are working normally.

If you have any further questions about how this product is given, ask your doctor, pharmacist or nurse.

  • fever, chills, a sore throat or other signs of an infection, or if you bruise easily. These may be signs of a problem with your blood cells
  • the Jarisch-Herxheimer reaction which occurs during treatment with Amoxicillin for Lyme disease and causes fever, chills, headache, muscle pain and skin rash
  • inflammation of the large bowel (colon) with diarrhoea (sometimes containing blood), pain and fever
  • serious liver side effects may occur which are often reversible. They are mainly associated with people having treatment over a long period, males and the elderly. You must tell your doctor or nurse urgently if you get:
    • severe diarrhoea with bleeding
    • blisters, redness or bruising of the skin
    • darker urine or paler stools

    DIES has been reported mainly in children receiving amoxicillin.
    It is a certain kind of allergic reaction with the leading symptom of repetitive vomiting (1-4 hours after drug <intake> <administration> <use>). Further symptoms could comprise abdominal pain, lethargy, diarrhoea, and low blood pressure
  • crystals in urine leading to acute renal injury
  • rash with blisters arranged in a circle with central crusting or like a string of pearls (linear IgA disease)

  • kidney problems
  • fits (convulsions), seen in patients on high doses or with kidney problems
  • dizziness
  • hyperactivity
  • crystals in the urine, which may be seen as cloudy urine, or difficulty or discomfort in passing urine. Make sure you drink plenty of fluids to reduce the chance of these symptoms
  • an excessive breakdown of red blood cells causing a form of anaemia. Signs include: tiredness, headaches, shortness of breath, dizziness, looking pale and yellowing of the skin and the whites of the eyes
  • low number of white blood cells
  • low number of cells involved with blood clotting
