What medicaton can cause a positive ana?

Certain medications can induce a positive antinuclear antibody (ANA) test, including hydralazine, procainamide, isoniazid, and certain anticonvulsants like phenytoin. These drugs can trigger drug-induced lupus erythematosus, which is characterized by the presence of ANA. It's important for healthcare providers to consider medication history when interpreting ANA test results.
