The antibiotic Flucloxacillin can be used to treat an infected toenail if you are not allergic to penicillins. Before you start treatment, always read the manufacturers leaflet contained with the medication. This contains more information and lists all the potential side effects.
The dose is to be taken four times a day, it is important that you space out the doses evenly during the day. Swallow the capsule with water, and take it on an empty stomach. This means an hour before food or 2 hours after food.
Do not take Flucloxacillin if you are allergic to Penicillin.
Keep taking Flucloxacillin until the full course is finished (unless a doctor tells you to stop), even if you feel that the infection has cleared up. This is to stop the infection from coming back. If you forget to take a dose, take one as soon as you remember unless it's nearly time for your next dose. In this case, just leave out the missed dose and take your next dose as normal.
Never give your medication to other people even if their condition appears to be the same as yours.
