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.

• 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.

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.

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.

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

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.

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.

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.

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

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

Amoxicillin 1000mg powder for solution for injection contains 59.4mg of sodium.

This should be considered if you are on a controlled sodium diet.

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.

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

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.

The following are very rare (may affect up to 1 in 10,000 people)

• allergic reactions, the signs may include: skin itching or rash, swelling of the face, lips, tongue, body or breathing difficulties. These can be serious and occasionally deaths have occurred
• rash or pinpoint flat red round spots under the skin surface or bruising of the skin. This is due to inflammation of blood vessel walls due to an allergic reaction. It can be associated with joint pain (arthritis) and kidney problems
• a delayed allergic reaction can occur usually 7 to 12 days after having amoxicillin, some signs include: rashes, high temperature (fever), joint pain, and enlargement of the lymph nodes especially under the arms
• a skin reaction known as ‘erythema multiforme’ where you may develop: itchy reddish purple patches on the skin, especially on the palms of the hands or soles of the feet, ‘hive-like’ raised swollen areas on the skin, tender areas on the surfaces of the mouth, eyes and genitals. You may have a fever and be very tired

• 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
  • yellowing of the skin or the whites of the eyes (jaundice). See also anaemia below which might result in jaundice.
• chest pain in the context of allergic reactions, which may be a symptom of allergy triggered cardiac infarction (Kounis syndrome)
• Drug-induced enterocolitis syndrome (DIES):
  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)
• inflammation of the membranes that surround the brain and spinal cord (aseptic meningitis).

These can happen when having the medicine or for up to several weeks after.

If any of the above occurs talk to your doctor or nurse straight away.

• a mildly itchy rash (round, pink-red patches), ‘hive-like’ swollen areas on forearms, legs, palms, hands or feet. This is uncommon (may affect up to 1 in 100 people).

If you have any of these talk to your doctor or nurse as Amoxicillin will need to be stopped.

• 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
