How does fusidic acid work?
Fusidic acid prevents bacteria from making essential proteins, stopping their growth and allowing the immune system to clear the infection.
What is fusidic acid used to treat?
Fusidic acid is commonly prescribed for:
- Impetigo (a contagious bacterial skin infection)
- Infected eczema or dermatitis
- Infected cuts, wounds, or burns
- Boils and folliculitis
Who can use fusidic acid?
Fusidic acid is suitable for most adults and children, including infants, depending on the severity of the infection.
Who might not be able to use fusidic acid?
Fusidic acid may not be suitable if you:
- Have a history of allergic reactions to fusidic acid or similar antibiotics
- Have severe or widespread skin infections that need oral antibiotics
Can I use fusidic acid if I’m pregnant or breastfeeding?
Fusidic acid is generally considered safe during pregnancy and breastfeeding, but speak to your doctor before using it on large areas of skin.
What if I miss a dose?
If you forget a dose, apply it as soon as you remember. If it’s close to your next dose, skip the missed one—do not apply extra to make up for it.
How effective is fusidic acid?
Fusidic acid is highly effective at treating bacterial skin infections when used consistently as prescribed.
What should I do if I use too much?
Using too much fusidic acid is unlikely to cause harm, but excessive use may lead to skin irritation or antibiotic resistance. If irritation occurs, speak to your doctor or pharmacist.

- For skin infections: Apply a thin layer to the affected area 2 to 3 times daily for 7 to 10 days
- For eye infections (as an eye drop): One drop every 12 hours for up to 7 days
Your doctor will determine the correct duration based on your infection.
