This leaflet is about the use of the antibiotic flucloxacillin for the treatment of bacterial infections.
This leaflet has been written specifically about the use of this medicine in children. The information may differ from that provided by the manufacturer. Please read this leaflet carefully. Keep it somewhere safe so that you can read it again.
If your child has ever had a reaction to any medicine, check with your doctor that your child can have flucloxacillin before giving it.
Common brands: Floxapen®, Fluclomix®, Ladropen®
It is important that your child takes this medicine in the way that your doctor has told you to so that it kills the harmful bacteria and gets rid of their infection.
Flucloxacillin is usually given four times a day. This is usually first thing in the morning (before breakfast), at about midday (before lunch), late in the afternoon (before tea) and at bedtime. Ideally, these times should be at least 3 hours apart.
Your doctor will work out the amount of flucloxacillin (the dose) that is right for your child. The dose will be shown on the medicine label.
It is important that you follow your doctor’s instructions about how much to give.
Flucloxacillin can be taken with or without food.
Capsules should be swallowed whole with a glass of water, milk or juice. Your child should not chew the capsules.
Liquid medicine: Shake the medicine well. Measure out the right amount using a medicine spoon or oral syringe. You can get these from your pharmacist. Do not use a kitchen teaspoon as it will not give the right amount. You can also dilute the right amount of medicine (measured with a spoon) in a small amount of water or milk. Make sure your child takes it all straight away.
It is important that you give your child the whole dose each time.
Your child should start to get better after taking the medicine for 2 days. It is important that they take the whole course of medicine that has been prescribed. Do not stop early.
If your child is sick again, seek advice from your GP, pharmacist or hospital. They will decide what to do based on your child’s condition and the specific medicine involved.
Never give a double dose of flucloxacillin.
Flucloxacillin is normally a safe drug. It is unlikely to cause any problems if you give an extra dose by mistake.
If you think your child may have had too much flucloxacillin, contact your doctor or local NHS Dservices (111 in parts of England; 0845 4647 in parts of England and Wales; 08454 24 24 24 in Scotland). Have the medicine or packaging with you if you telephone for advice.
We use medicines to make our children better, but sometimes they have other effects that we don’t want (side-effects).
Side-effects are rare with flucloxacillin and do not usually last for long. They will get better after a day or two as your child’s body gets used to the medicine, and should go away when the treatment course is finished.
If your child gets a skin rash or itching, has problems breathing or seems short of breath or is wheezing, or if their face, throat, lips or tongue start to swell, they may be allergic to flucloxacillin. Take them to hospital or call an ambulance straight away.
There may, sometimes, be other side-effects that are not listed above. If you notice anything unusual and are concerned, contact your doctor. You can report any suspected side-effects to a UK safety scheme at http://yellowcard.mhra.gov.uk.
If you think someone else may have taken the medicine by accident, contact your doctor straight away.
Your child should not have flucloxacillin if they are allergic to penicillin antibiotics. You must tell your doctor if your child has ever had an allergic reaction or other reaction to any medicine. If you have forgotten to tell your doctor, check with the doctor or pharmacist before giving flucloxacillin to your child.
Your child should not have flucloxacillin if they have ever had liver problems or jaundice (yellowing of the skin or whites of the eyes), other than jaundice in the few weeks after birth (which is normal).
Your child’s doctor, pharmacist or nurse will be able to give you more information about flucloxacillin and about other medicines used to treat infections.
