Patients with hypertension must use effective medications to keep their blood pressure within the normal range to prevent damage to the cardiovascular and cerebrovascular systems. During medication use, patients should not arbitrarily stop taking their medication or switch to different types. It is necessary to regularly monitor blood pressure and adjust the medication dosage or switch types under the guidance of a doctor as blood pressure fluctuates. Randomly stopping medication and discontinuing antihypertensive drugs can cause blood pressure fluctuations and pose greater risks to the body, especially causing ischemia in the heart and brain.
