Can I take antihypertensive medication to control blood pressure before a physical examination?

Before the physical examination, antihypertensive medication can usually be taken to control blood pressure, but the medication time needs to be adjusted according to the specific type of medication and physical examination items. Routine physical examinations such as blood and urine tests are generally not affected by antihypertensive drugs, but some antihypertensive drugs may interfere with specific test results. Short acting antihypertensive drugs such as nifedipine tablets may need to be taken 4-6 hours before the physical examination to avoid affecting the accuracy of blood pressure measurement. Long acting antihypertensive drugs such as amlodipine tablets are recommended to maintain the original medication regimen due to their long duration of action. Hypotension drugs containing diuretic components, such as hydrochlorothiazide tablets, may affect electrolyte testing, and it is necessary to communicate with a doctor in advance to determine whether to adjust. Beta blocker antihypertensive drugs such as metoprolol extended release tablets may interfere with the interpretation of electrocardiogram results, and medication may be delayed if necessary. Sudden discontinuation of medication in hypertensive patients may lead to a rebound increase in blood pressure, increasing the risk of cardiovascular and cerebrovascular diseases. Before physical examination, self adjustment of dosage should be avoided, especially for patients with diabetes or renal insufficiency. If special examinations such as dynamic blood pressure monitoring or exercise stress testing are required, it is recommended to confirm the medication plan with the attending physician 3 days in advance. When taking angiotensin converting enzyme inhibitor antihypertensive drugs such as perindopril tablets, attention should be paid to the possibility of temporarily increasing blood creatinine levels.

Before the physical examination, one should maintain a normal diet and daily routine, avoid vigorous exercise and emotional fluctuations. Wear loose clothing for easy blood pressure measurement, and sit quietly for 5 minutes before the measurement. Truthfully inform the doctor of medication history and past medical history, and bring daily medication records for reference. If the physical examination includes fasting items, a small amount of water can be used to administer antihypertensive medication. After the physical examination, if abnormal fluctuations in blood pressure are found, timely follow-up visits should be made, and a specialist doctor should evaluate whether the treatment plan needs to be adjusted.
