If you take too many antihypertensive drugs, you should do this: First, monitor your blood pressure frequently, measure it every 1-2 hours, or even every 0.5 hours, and record it. If the blood pressure drops significantly, below 90/60mmHg, there will be uncomfortable manifestations, such as dizziness, weakness, chest tightness, breath-holding, panic, etc., you need to go to a regular hospital immediately and get timely and standardized treatment. Second, if the blood pressure is above 90/60mmHg and there are no uncomfortable manifestations, you can observe temporarily, but you still need to measure the blood pressure every 0.5-1 hour and record it to understand the fluctuation of blood pressure. Third, most of the drugs can be metabolized completely in the body after 1 day or even 0.5 days. By measuring blood pressure several times, if there is no tendency for blood pressure to drop, it can be considered safe and effective. Fourth, we should avoid taking too many antihypertensive drugs in the future. As long as the drugs are prescribed, they should be taken under the guidance of a doctor or pharmacist in a regulated manner, and should not be taken haphazardly.
