Warnings

In a few patients hydralazine may produce a clinical picture simulating systemic lupus erythematosus including glomerulonephritis.

In such patients hydralazine should be discontinued unless the benefit-to-risk determination requires continued antihypertensive therapy with this drug.

Symptoms and signs usually regress when the drug is discontinued but residua have been detected many years later.

Long-term treatment with steroids may be necessary.
