The difference is... Drug induced lupus means that the disease (systemic lupus erythematous) was caused by a certain drug. Systemic refers to ability to affect different systems. With drug induced, symptoms will resolve after stopping medications.
See answer. Dil is caused by a drug and usually resolves without treatment once the drug is stopped. Systemic lupus erythematosus is not caused by a drug, does not typically resolve on its own and usually does require treatment. Dil is not likely to cause kidney damage while systemic lupus erythematosus usually does.
