Autoimmune Disease
Steroid Therapy

Psoriasis is primarily a skin condition caused by an autoimmune process. Sometimes the disease is treated with powerful drugs and/or ultraviolet radiation to suppress the underlying autoimmune process. This may be with treatment with PUVA, methotrexate, ciclosporin, hydroxycarbamide etc. and this may alter the body's defence mechanisms to infection.
 

Etretinate (Tigason^®) and acitretin (Neotigason^®) can cause birth defects in babies exposed to them while inside the womb. It is important to allow time for the drug to be cleared from the blood of a donor. It takes longer to clear some drugs than others.

A discretion to accept donors on oral medication has been added and the text has been updated to ensure consistency with other DSG references to immunosuppression.
