Discharge Instructions for Malignant Hypertension (Hypertensive Emergency or Urgency)

Malignant hypertension is very high blood pressure that causes harm to your organs. It is a medical emergency. There are 2 types of hypertensive crisis:

Hypertensive emergency. This means you have dangerously high blood pressure that is harming organs in your body. For this, the top number of a blood pressure reading is usually higher than 180 and/or a bottom number is higher than 120. You will also have symptoms that mean organs in your body are being harmed. This severe high blood pressure can cause damage to your heart, kidneys, brain, eyes, blood vessels, and other organs. See list of symptoms at the end of the page.

Hypertensive urgency. This is when your blood pressure is 180/120 but you aren't having any symptoms that mean your organs are being affected. This should still be addressed. You will need to take steps to lower your blood pressure. This is done by taking blood pressure medicine as well as changing your diet and exercise habits.

Below are instructions for how to manage your high blood pressure.

Taking your blood pressure

  • Learn to take your own blood pressure. Be sure you know how to take a blood pressure right. Your healthcare provider can give you detailed instructions. This is most often done by using an at home blood pressure machine. Your provider can help you with choosing a reliable home blood pressure monitor. You must be sitting and resting for 5 minutes before taking your blood pressure.

  • Keep a record of your blood pressure results. Ask your provider which readings mean that you need medical attention.

  • Have your blood pressure checked by your provider regularly.

  • Hypertensive emergency. If you have a blood pressure measure at home that is higher than 180/120 and you have any symptoms shown at the end of this page, don't wait to see if it comes back down. Get emergency medical care right away.

  • Hypertensive urgency. If you have a blood pressure measure at home that is higher than  180/120 wait 5 minutes and take it again. If the second reading shows either number at or above the first reading and you are not having any symptoms listed at the end of the page, this is a hypertensive urgency. Contact your provider right way. You may need to change your medicines.

Taking medicines

  • Take your blood pressure medicine exactly as your provider directed. 

  • Learn the possible side effects of any prescribed medicines.

  • Tell your provider about any medicine you are taking. Some medicines can cause malignant hypertension.

  • Don't take medicines that contain heart stimulants. This includes some over-the-counter medicines. Check for warnings about high blood pressure on the label.

  • Check with your provider before taking a decongestant. Some can make high blood pressure worse.

Lifestyle changes

  • Limit your activity until your blood pressure is controlled.

  • Cut back on salt.

    • Limit canned, dried, packaged, and fast foods.

    • Don’t add salt to your food at the table.

    • Season foods with herbs instead of salt when you cook.

    • Request foods at restaurants with no added salt.
