Fusidic acid is indicated in the treatment of all staphylococcal infections due to susceptible organisms such as:

• osteomyelitis
• pneumonia
• septicemia
• wound infections
• endocarditis
• superinfected cystic fibrosis

• eye infection
• bacterial conjunctivitis

Osteomyelitis	Pneumonia	Septicemia	Endocarditis
Skin Infection	Eye Infection	Conjunctivitis	Keratitis

Fusidic acid is available as cream, suspension and ophthalmic drops.

• Systemic Fucidin and statins (HMG-CoA reductase inhibitors) should not be taken together. Rhabdomyolysis (including fatalities) has been reported in people receiving this combination.
• With systemic Fucidin, significant cutaneous responses placing lives at risk have been documented, including Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome, toxic epidermal necrolysis (Lyell's syndrome), and Stevens-Johnson syndrome.
• The liver metabolizes fusidic acid, which is then expelled in the bile. Elevated liver enzymes and jaundice have been reported with systemic Fucidin therapy, however these side effects are usually reversible once the medicine is stopped.
• The usage of fusidic acid has been linked to the development of bacterial resistance. Extensive or recurrent use of antibiotics, like with all drugs, increases the chance of acquiring antibiotic resistance.
