The worst side effects of hydralazine include severe hypotension (dangerously low blood pressure), lupus-like syndrome (with symptoms such as joint pain, fever, and rash), and heart-related issues like tachycardia (rapid heartbeat) or heart failure. Rarely, it can also cause blood disorders such as agranulocytosis. If you experience chest pain, difficulty breathing, or signs of an allergic reaction, seek medical attention immediately.
