Whether or not you can stop taking antihypertensive drugs when your systolic blood pressure is 110mmHg and diastolic blood pressure is 80mmHg depends on the situation. Patients with primary hypertension need to continue to take antihypertensive drugs when their blood pressure drops to normal, while patients with secondary hypertension can stop taking antihypertensive drugs after their blood pressure drops to normal after treatment of the primary disease. 1. Hypertension is a chronic disease, patients with primary hypertension need to take long-term medication to lower blood pressure. Patients with hypertension should continue to use antihypertensive drugs or change them after their blood pressure has been reduced to normal by medication. If you stop taking the medication privately, the blood pressure will rise again, and the long-term elevation of blood pressure will cause damage to target organs such as the heart, brain, kidney, eyes, etc., which will easily increase the risk of coronary atherosclerotic heart disease, acute myocardial infarction, cerebral infarction, cerebral hemorrhage, renal arteriosclerosis and other diseases, and will seriously jeopardize the life and health of the patient. 2. Secondary hypertension can stop using antihypertensive drugs if the primary disease is cured and the blood pressure returns to normal. Whether to stop using drugs after the blood pressure returns to normal or not, it needs professional doctor’s judgment, not to stop using drugs privately, to avoid the mistake of the condition.
