Patients with hypertension must not stop taking their medication without permission, because it may lead to a sudden rebound in blood pressure, which is very detrimental to the condition. In particular, patients taking bisoprolol or metoprolol drugs should not suddenly stop the drug, because the sudden discontinuation of the drug may lead to a sudden increase in heart rate and blood pressure, and in serious cases, may induce angina pectoris, myocardial infarction. Patients with hypertension must take their medication on time, and should monitor their blood pressure every day, and if they find signs of low blood pressure, they can reduce the dosage appropriately. If you find that your blood pressure is not well controlled, you should increase your antihypertensive medication appropriately, and stopping it without permission is not advocated. High blood pressure requires year-round treatment, and taking antihypertensive drugs only relieves the symptoms of elevated blood pressure, but does not cure it.
