- liver disease - flucloxacillin treatment is very rarely associated with
an increased risk of hepatic disorders, namely, hepatitis and cholestatic
jaundice. In some patients, almost always those with serious underlying disease,
these adverse reactions have been fatal (1)
- onset of hepatic reactions may be delayed for several weeks (up to 2 months) after treatment with flucloxacillin has stopped
- these reactions are related neither to the dose nor to the route of administration of flucloxacillin
- risk factors include treatment for more than 2 weeks and increasing age
Routes of administration:
- slow i.v. injection
- i.v. infusion
