You still need to take blood pressure lowering medication even if your blood pressure is normal in the morning, because hypertension is a chronic disease and there is no cure for it. The purpose of lowering blood pressure is to keep it within the target range for a long time, so taking blood pressure-lowering medication to normalize blood pressure does not indicate that high blood pressure has been cured, and should still be taken for a long time. If blood pressure lowering medication is discontinued, the majority of patients will soon have their blood pressure rise again. For patients with hypertension, they must be prepared to take blood pressure-lowering drugs for a long time or even for life. Only when patients with hypertension achieve long-term blood pressure standards can they effectively reduce the damage to the target organs of the heart, brain and kidneys and prevent the occurrence of various comorbidities of hypertension, thus improving their prognosis.
