Hydralazine can cause interstitial lung disease, pauci-immune
glomerulonephritis and hypocomplementemia. Hydralazine- induced ANCA-
associated vasculitis and hydralazine-induced lupus are rare. We
describe a case of hydralazine-associated vasculitis with rapidly
progressive glomerulonephritis and highlight the importance of early
diagnosis and treatment as it can be rapidly progressive and fatal.
