Will taking Levofloxacin Hydrochloride Capsules the night before a medical examination affect the examination results?

Generally, taking levofloxacin hydrochloride capsules the night before a physical examination does not affect routine examination items. However, it may influence the results of tests related to liver and kidney function or specific drug concentration measurements. If any abnormalities occur, timely medical consultation is recommended. Detailed analysis is as follows:

Routine examination items such as complete blood count, electrocardiogram (ECG), and chest X-ray are generally not significantly affected by levofloxacin hydrochloride capsules in a short period. The test results can reflect the body's basic condition and are usually not influenced. In such cases, the drug is metabolized quickly and has minimal impact on baseline test values.

If the examination includes liver and kidney function tests or drug concentration measurements, levofloxacin hydrochloride is metabolized by the liver and excreted by the kidneys. This may cause slight fluctuations in liver function indicators such as transaminase or kidney function indicators such as creatinine. Drug concentration testing will directly detect the presence of the drug, thereby affecting the accuracy of the results.

Before the examination, inform the doctor about recent medication use and adjust the examination items or timing as advised by the doctor to ensure reliable results.
