Preventing Another Eczema Flare

Use the medication which your doctor recommends on a regular basis.
Use a soap substitute, to keep the skin supple and to prevent drying.
Avoid scratching when you itch. If you can not stop yourself, then gently rubbing, with the flat of your hand, is less likely to do damage.
Avoid exposure to chemicals and strong detergents. It is usually better to avoid using biological agents altogether.
Use protective gloves when you use such things in the house or at work.
If you have been found to be allergic to a specific substance, avoid contact with it, if this is feasible.
Use your treatments according to the instructions from your doctor and the pharmacist.
