Flucloxacillin

Flucloxacillin is an antibiotic that is part of the penicillin group of antibiotics. Therefore, if you are allergic to penicillin you will also be allergic to flucloxacillin.

Flucloxacillin is used to treat common bacterial infections such as skin, bone, ear, heart and chest infections. It is not used treat viral infections such as the common cold.

It is normally given 4 times per day and the dose that is given will be determined by your doctor as drug doses in children are calculated on the weight or age of the child.

If your child vomits less than 30 minutes after being given a dose of amoxicillin you should repeat the dose. If more than 30 minutes has passed you can assume that the medicine has been absorbed.

Side effects

If your child gets a skin rash or itching, is short of breath, wheezing, or their face, lips or tongue start to swell, they may be allergic to flucloxacillin. Take your child to hospital or call an ambulance straight away.

Other side effects may include stomach upset which usually settles after 24 hours. If it doesn’t you should arrange to see your GP.

Drug interactions

Although generally well tolerated, it is important to let your GP or pharmacist know of any other medications (including herbal) that you might be taking.
