A doctor’s decision is needed to decide whether the medication can be stopped. Primary hypertension usually cannot be stopped, while secondary hypertension can be stopped when the cause is treated. Hypertension is divided into primary hypertension and secondary hypertension. Primary hypertension has no clear cause and, once diagnosed, requires lifelong medication. Blood pressure returns to normal after taking medication because after taking antihypertensive medication, the medication, through its various effects in the body, allows the blood pressure to reach a normal level. Once the medication is stopped, the blood pressure will rise again as the medication is gradually metabolized in the body. Secondary hypertension is commonly caused by renal hypertension, renal vascular hypertension, primary aldosteronism, pheochromocytoma, cortisolism, aortic constriction and other diseases. The key is to treat the primary disease. After the primary disease is treated and the blood pressure returns to normal, antihypertensive drugs can be discontinued. After taking high blood pressure medication, blood pressure is normalized, whether the drug can be discontinued, must strictly comply with the doctor’s instructions to implement, privately stopping the drug, can cause adverse effects.
