Steroids are also produced synthetically in preparations to be taken by mouth, by injection and onto the skin in creams.
The creams are mainly used in the treatment of eczema.
Creams are available in very weak forms such as 1% hydrocortisone, or in much stronger formulations.
It is important to take medical advice about how strong your steroid creams are and in what quantities you should be applying them onto the skin. Strong steroids (either internally or onto the skin surface can have side effects after prolonged use).
