The most striking of these is the drug-induced lupus erythematosus.

The processes that lead to drug-induced lupus erythematosus are not entirely understood.

Symptoms of drug-induced lupus erythematosus generally disappear days to weeks after medication use is discontinued.

Signs and symptoms of drug-induced lupus erythematosus include:

An example is hydralazine, a blood pressure-lowering drug that occasionally can produce drug-induced lupus erythematosus in certain individuals.

Drug-induced lupus erythematosus is a (generally) reversible condition that usually occurs in people being treated for a long-term illness.

However, they can mimic a wide range of other conditions, thus delaying diagnosis (for example, in drug-induced lupus erythematosus, or the acne-like rash caused by erlotinib).

There are at least three forms of lupus: the classic form, systemic lupus erythematosus; a form that only affects the skin, discoid lupus erythematosus; and drug-induced lupus erythematosus.

Anti-histone antibodies are autoantibodies that are found in 50%-70% of patients with systemic lupus erythematosus (SLE) and in more than 95% of patients with drug-induced lupus erythematosus.

Drug-induced lupus erythematosus (DIL or DILE) is an autoimmune disorder (similar to systemic lupus erythematosus [SLE]) caused by chronic use of certain drugs.
