Overview

Fusidic acid is a powerful topical antibiotic that targets bacterial skin infections at their source. Containing fusidic acid 2%, it works by stopping bacteria from multiplying, helping your skin heal while easing redness, soreness, and irritation.

Available as a cream (light, quick-absorbing) or ointment (richer, protective), Fusidic acid is often prescribed for infected eczema, dermatitis, or impetigo, giving your skin the chance to recover without further damage.

This treatment requires a secure online consultation with a UK-registered prescriber, and will only be supplied if clinically appropriate.


What is Fusidic acid


Fusidic acid is a topical antibiotic medicine that’s highly effective against Staphylococcus aureus — the bacteria most commonly linked with infected eczema and other skin conditions.

It’s usually prescribed for short courses (7–10 days) to treat:

  • Infected eczema or dermatitis patches
  • Impetigo (crusty, yellowish skin infection)
  • Infected cuts, grazes, or wounds
  • Other superficial bacterial skin infections


Unlike steroid creams, Fucidin does not reduce inflammation directly — instead, it clears infection, which then allows the skin to calm and heal naturally.

Directions

  • Apply a thin layer to the affected area three times daily, unless instructed otherwise.
  • Use sparingly — only enough to cover infected skin.
  • Wash hands before and after application.
  • Do not cover with airtight dressings unless advised by your prescriber.
  • Complete the full course, even if skin looks better sooner.

Side Effects

Like all medicines, Fusidic acid can cause side effects, although not everyone will experience them. Side effects are usually mild and temporary.

Common (may affect up to 1 in 10 people)

  • Temporary stinging or burning
  • Itching or mild irritation


Rare (may affect up to 1 in 1,000 people):

  • Rash or worsening of eczema
  • Signs of allergy such as redness, swelling, or blistering


Most people tolerate Fusidic acid well, and side effects (if they do occur) are usually mild. If you are concerned about any symptoms, or they do not improve, speak to your doctor, pharmacist, or prescriber.

Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet provided with your medicine for full details. If you experience severe or worrying symptoms, seek medical advice straight away. In an emergency, call 999 or go to A&E.

Warnings

  • Do not use if allergic to fusidic acid or any ingredient in the cream/ointment.
  • Not suitable for viral or fungal skin infections (e.g. cold sores, athlete’s foot).
  • Avoid prolonged use — overuse may lead to antibiotic resistance.
  • Only use during pregnancy or breastfeeding if recommended by a prescriber.

FAQ's

Is Fusidic acid an antibiotic or steroid?
Fusidic acid is a topical antibiotic, not a steroid. It’s designed to clear bacterial skin infections.

Can Fusidic acid be used for eczema?
Yes — but only when eczema patches are infected. For non-infected eczema, a steroid cream like Hydrocortisone or Eumovate is usually prescribed.

How long should I use Fusidic acid for?
Typically 7–10 days, or as advised by your prescriber. Longer use increases the risk of resistance.

What’s the difference between Fusidic acid Cream and Ointment?
Cream is lighter and more suitable for moist or weeping infections, while ointment is thicker and better for dry or scaly areas.

Does Fusidic acid work immediately?
Many people notice improvement within a few days, but it’s important to complete the full course.
