Treating Eczema Flare-Ups: Using Steroid Creams Safely
Key Information
- Regaining Control: During an eczema flare-up (red, inflamed, itchy skin), moisturisers alone are often not enough. Steroid creams or ointments are used to calm the inflammation.
- Safety Assurance: When used correctly for short periods, steroid creams are safe and the most effective treatment for flare-ups.
- The Goal: To settle the inflammation so you can return to regular emollient use alone.
The “Fingertip Unit”: Getting the Dosage Right
The key to safe use is applying the correct amount.
- The Measurement: One Fingertip Unit (FTU) is the amount of cream squeezed from the tube along your index finger (from the tip to the first crease).
- The Coverage: This amount treats an area of skin roughly twice the size of your palm.
Using this guide helps ensure you apply the right amount — not too little, and not too much.
How to Apply
- Target the Inflammation: Apply only to red, inflamed, itchy areas — not to normal skin.
- Thin Layer: Smooth a thin layer gently into the skin (usually once daily).
- The 30-Minute Gap: Continue using your emollient, but wait about 30 minutes after applying the steroid before applying moisturiser.
- Know When to Stop: Use daily until the skin is no longer red, itchy, or inflamed. Then stop and continue with emollients alone.
When to Seek Help
- If the flare-up is not improving after one week.
- If the skin becomes weepy, crusted, or shows signs of infection.
