If the antihypertensive drug lowers the low pressure too low, it is recommended to stop the antihypertensive drug temporarily. If accompanied by obvious symptoms of low blood pressure, such as dizziness, lightheadedness, fatigue, poor vision, etc., it is recommended to drink some saline water and some Chinese medicines with blood pressure-boosting effect, such as pulse-boosting drink, Astragalus essence, and Yiqi rejuvenation granules. If the antihypertensive effect is not obvious and there are still clinical symptoms, it is recommended to apply intravenous antihypertensive drugs, commonly used drugs include dopamine, dobutamine, m-hydroxylamine, etc., to raise the blood pressure to normal, so as not to cause insufficient perfusion of the heart, brain, and kidneys due to the prolonged low blood pressure, which may cause myocardial ischemia, angina pectoris, cerebral infarction, and renal hypoplasia, etc. In addition, it is recommended to take some oral antihypertensive drugs, which can help to reduce the blood pressure. During the period of oral antihypertensive drugs, blood pressure must be measured twice a day, so as not to lower the blood pressure too low to affect the heart, brain, kidney and other functions.
