Can I take medicine the day before a physical examination?

With the continuous improvement of daily living standards, people pay more and more attention to their physical health. Most people usually have the habit of physical examinations. Physical examinations are usually to find some hidden diseases in the body in time. Many diseases can be found and treated early. However, there are some precautions when people usually have physical examinations. If you take medicine the day before, can you still have a physical examination?

Can I take medicine the day before the physical examination?

1. Do not take antibiotics before urine or blood tests

Because antibiotics may increase the concentration of uric acid in the blood, and after taking sulfonamides, the urine urobilinogen test will appear turbid, affecting the judgment of the test results. Therefore, if the patient undergoes urine or blood tests, do not take these medications 48 hours before the examination. These drugs will be diluted in the body after 48 hours and will not affect the test results.

2. Stop taking analgesics and anti-inflammatory drugs 72 hours before the physical examination

These drugs can easily lead to increased amylase levels in the blood and urine, and their effects will reach their peak 3 to 4 hours after taking the drugs.

3. Stop taking diuretics 24 hours before blood test

They can lower the potassium level in the blood, leading to changes in blood electrolyte results.

However, it should be noted that even if you want to stop taking the above medications, you must obtain the doctor's consent. Especially for patients with diabetes and hypertension, blood sugar and blood pressure lowering drugs cannot be stopped at will, otherwise unexpected situations may easily occur. Detailed consultation is required before the physical examination.

Things to note before the physical examination

First: Get enough rest before the physical examination: If you don’t get enough rest a few days before the physical examination, it will affect your blood sugar, blood lipids and blood pressure values. Avoid strenuous exercise and emotional excitement, and ensure adequate sleep to avoid affecting the results of the physical examination. It would be best to take a shower. When preparing for a medical examination, it is recommended to avoid eating and strenuous exercise after 8 pm before the examination. This is the most important thing to note before a physical examination, and it is also an issue that many people ignore.

Second: In the few days before the physical examination, you should pay attention to your diet, not eat too much greasy or indigestible food, not drink alcohol, and not take medicines that are harmful to liver and kidney function.

Third: Women should avoid the menstrual period before physical examination.

Fourth: Do not take any medications 3 days before the physical examination, because the effects of various medications in the body may affect the accuracy of the physical examination.

Fifth: When middle-aged people have their annual health check-up, they should pay attention to testing the uric acid concentration in the blood. Since purine foods have an impact on uric acid testing, they should not eat foods containing purine, such as animal offal and seafood.
