What Floxapen capsules are and what they are used for
Flucloxacillin is an antibiotic used to treat infections by killing the bacteria that can cause
them. It belongs to a group of antibiotics called “penicillins”.
Floxapen capsules are used to treat:
• chest infections
• throat or nose infections
• ear infections
• skin and soft tissue infections
• heart infections
• bones and joints infections
• meningitis
• digestive system infections
• blood infections
• kidney, bladder or urethra (the tube which carries urine from the bladder) infections.
Floxapen capsules can also be used to prevent infections during major surgery, particularly
heart or orthopaedic surgery.

Before you take
Do not take Floxapen capsules and tell your doctor if you:
• are allergic (hypersensitive) to flucloxacillin, penicillin, any other antibiotic or any of the
other ingredients (see section 6)
• have ever had liver problems after taking flucloxacillin.
Check with your doctor or pharmacist before taking Floxapen capsules if you:
• have liver or kidney problems
• have any serious illness, other than this infection
• are on a low sodium diet




are 50 years old or over.
are taking or will be taking paracetamol.
There is a risk of blood and fluid abnormality (high anion gap metabolic acidosis) which occurs
when there is an increase in plasma acidity, when flucloxacillin is used concomitantly with
paracetamol, particularly in certain groups of patients at risk, e.g. patients with severe renal
impairment, sepsis or malnutrition, especially if the maximum daily doses of paracetamol are used.
High anion gap metabolic acidosis is a serious disease that must have urgent treatment.

Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other
medicines, including medicines obtained without a prescription. Especially:
• probenecid (to treat gout)
• other antibiotics (used to treat infections)
Pregnancy and breast feeding
If you are pregnant, planning to become pregnant or are breast feeding ask your doctor or
pharmacist for advice before taking this medicine.
Tests
Regular monitoring of liver and kidney function should be performed whilst taking Floxapen
capsules.
Tell your doctor that you are taking Floxapen if you are having urine tests or blood tests
because Floxapen may affect the results.

How to take
Always take Floxapen capsules exactly as your doctor has told you. If you are not sure, check
with your doctor or pharmacist.

Never take more than the recommended dose each day.
Doses:
• Adults - one 250mg capsule four times a day, your doctor may prescribe a different dose
for severe infections.
• Joint infections (osteomyelitis) or heart infections (endocarditis) - up to 8g daily in divided
doses, six to eight hourly.
• To prevent infection due to surgery - 1 to 2g by injection into a vein, at the same time as
the anaesthetic, followed by 500mg six hourly either by mouth or injection into a vein or
muscle for up to 72 hours.
• Children aged 2-10 years - half the adult dose.
• Children under 2 years - quarter the adult dose.
• Premature or babies less than 4 weeks old – Not recommended.
• Severe kidney disease - your doctor may reduce your dose.

If you still feel unwell after finishing the treatment, speak to your doctor.
If you take more than you should
If you (or someone else) swallow a lot of capsules at the same time, or you think a child may
have swallowed any contact your nearest hospital casualty department or tell your doctor
immediately. Symptoms of an overdose include feeling or being sick and diarrhoea.
If you forget to take the capsules
Do not take a double dose to make up for a forgotten dose. If you forget to take a dose take it
as soon as you remember it and carry on as before, try to wait about four hours before taking
the next dose.
If you stop taking the capsules
Do not stop treatment early because some bacteria may survive and cause the infection to
come back.
