If the systolic blood pressure is between 60 and 90 mmHg after taking antihypertensive drugs, hypertensive patients need to consult a doctor in time and take reasonable measures to raise the blood pressure. If the diastolic pressure is 60~90mmHg, it is in the normal range. After taking antihypertensive drugs, systolic blood pressure is between 60 and 90mmHg, which means that the blood pressure is too low at this time, and there will be insufficient blood supply, shock or even sudden death, etc. It is necessary to go to the hospital in time to seek medical treatment, and to use reasonable means to raise blood pressure, such as stopping antihypertensive drugs in time, and using pressure-boosting drugs, such as dopa-phenol-butylamine, etc. appropriately. If the diastolic blood pressure is at 60~90mmHg, it means that the hypertensive patients are taking drugs with good blood pressure control. At this time, you can maintain the dose for a long time, if the diastolic blood pressure is unstable, you need to consult a doctor in time to adjust the type and dose of drugs. In summary, when the systolic blood pressure is 60~90mmHg after taking the drug, it is necessary to consult a doctor in time to prevent the occurrence of life-threatening situations, and if the diastolic blood pressure is 60~90mmHg, it is necessary to review it regularly to keep the blood pressure stable. Antihypertensive drugs are prescription drugs and should be used under the guidance of a doctor to avoid self-medication.
