Special instructions

  • Store the tablets at room temperature in a dry place.
  • Take hydralazine with food. Food increases the amount of drug that gets in your body. If you cannot take this with food every time, then always take it without food. It is important to take this medicine the same way and at the same time each day, so your blood pressure is controlled with the same amount of medicine each day.
  • This medicine may cause you to feel dizzy and lightheaded. Do not operate heavy equipment or drive a motor vehicle until you see how this medicine will affect you. To avoid feeling dizzy or having fainting spells do not sit up or stand up too quickly.
  • You or your nurse should check your blood pressure and heart rate regularly while you are taking hydralazine. Your doctor will tell you what to do if your blood pressure level is low or high. Your dose of hydralazine may change based on your blood pressure level. If your blood pressure is above _____________ or below__________, call your doctor right away. If your heart rate is _____________, call your doctor right away.
  • Hydralazine may affect the way some medicines work. Some medicines may also affect the way hydralazine works. These medicines include:
    • Other blood pressure medicines
    • Medicines for colds and coughs
    • Ibuprofen and other anti-inflammatory medicines
    • Medicines for depression
    • Female hormones (including birth control medicines)
    • Diuretics
    • Alcohol
  • Always tell your doctor if you are taking any of these medicines, or if you start taking any new medicine while you are taking hydralazine.
  • If you have a sudden onset of severe diarrhea or vomiting or if you sweat a lot, tell your doctor right away. This loss of body fluid may decrease your blood pressure.
