Patients with hypertension should not reduce their medication at will after their blood pressure has been controlled normally with antihypertensive drugs, and they should not stop taking the drugs suddenly because hypertension is a chronic disease that requires long-term antihypertensive treatment. If blood pressure is well controlled after taking medication, reducing the dose of antihypertensive medication at this time may cause fluctuations in blood pressure, which may be detrimental to patients with hypertension. As long as the blood pressure can be controlled in the target range through antihypertensive drugs, it is necessary to take antihypertensive drugs for a long time, and if there are no other abnormalities, such as blood pressure falling too low, the dosage should not be reduced at will, and the antihypertensive drugs should not be stopped at will.
