Sometimes infection can cause auto-antibodies to be produced and this may be one of the causes of Lupus. The antibodies circulate in the blood, but some of the body's cells have walls permeable enough to let some antibodies in. These can then attack the DNA in the cell's nucleus. That's why some organs can be attacked during a flare while others aren't. Drug-induced lupus may develop after taking certain prescription medications.
Symptoms generally disappear after the drug is discontinued.
Some people will have only a few symptoms, others may have them all. Discoid Lupus is confined to the skin, whereas systemic lupus may involve any organ system in the body, as well as the skin. However, this can't be predicted or prevented from happening. Systemic lupus is irreversible, whereas drug-induced lupus generally is reversible. There are other drugs which might possibly be associated with drug-induced lupus, but as yet there is no definite proof.
