Whether a hypertensive patient can stop taking medication after his blood pressure is normalized needs to be judged in the light of his condition. If it is primary hypertension, after taking antihypertensive drugs in regular compliance with the doctor’s instructions, the blood pressure drops to the normal range; at this time, the drug cannot be stopped to avoid causing the blood pressure to rise again, which will lead to dizziness, headache discomfort, and in severe cases, acute heart, brain and kidney related organ damage. If secondary hypertension is diagnosed, such as pheochromocytoma, cortisolism, primary aldosteronism and other diseases; usually after surgical resection and treatment, together with the anti-hypertensive drugs such as Elapril and Valsartan, the blood pressure will be controlled within the ideal range, and then the drug can be stopped after the doctor combined with the comprehensive assessment of the condition. When the above symptoms occur, it is recommended to go to the hospital in a timely manner, and remember not to stop the medication privately to avoid adverse reactions.
