What should I do now?

Call 911

Call 911 for chest pressure, severe trouble breathing, or sudden weakness, trouble speaking, or vision changes. Do not wait for a BP reading. Very high BP with these symptoms is an emergency.

Contact your care team

If the top number is above 180 or the bottom number above 120 without concerning symptoms, repeat after at least 1 minute. If still this high, contact your clinician immediately. Do not take extra medicine without instructions.

Keep your care plan

Keep your treatment and follow-up plan. Bring questions, readings, and your medication list.

SECTION 5

Living well with high blood pressure

High blood pressure usually needs ongoing management. A normal reading while taking medication often means your treatment is working.

Take medications consistently

Take your medication as prescribed, even when you feel well. Do not stop it because your readings improve.

Tell your care team about side effects, cost, or difficulty remembering doses. They can help adjust your plan.

Keep a home blood pressure record

Measure using the technique described in Section 3 and follow your care team’s schedule. Record your readings and bring them to appointments.

Look at the pattern over time. Do not change your medication based on a single reading unless your clinician has given you specific instructions.

Make healthy habits sustainable

Choose changes you can maintain: cook more meals at home, read sodium labels, walk regularly, and establish a consistent sleep routine.

Keep follow-up visits and lab appointments

Visits help your care team review your readings and adjust treatment. Some medications require blood tests to monitor kidney function and electrolytes, including potassium.

Know when to get help

Contact your care team if readings repeatedly remain above your goal or you develop dizziness, weakness, or unusually low readings.

For chest pain, severe shortness of breath, or signs of a stroke, call 911.

If your top number is above 180 or your bottom number is above 120 without symptoms, repeat the measurement after at least one minute. If it remains this high, contact your healthcare professional immediately.
