Introduction
If routine blood tests such as complete blood count or lipid profile are performed, the impact of medications on these indicators is generally minimal. After taking medication for 1–2 weeks, the body has usually adapted to the drug to some extent, and testing at this time can better reflect the body's baseline health status. This helps avoid potential minor short-term fluctuations caused by initial medication use that might interfere with test results, while also preventing the need to deliberately discontinue medication, which could negatively affect disease control.

Under normal circumstances, if blood tests for routine physical examinations are needed after taking flupentixol-melitracen tablets, they can be conducted 1–2 weeks after starting the medication. However, if the purpose is to monitor the drug's impact on organ functions such as liver and kidney function, the first blood test should be performed approximately one month after starting treatment, as directed by a physician. If there are any concerns, it is recommended to consult a doctor in advance. Detailed explanations are as follows:

If undergoing routine blood tests, such as complete blood count or lipid profile, the medication has minimal influence on these indicators. After 1–2 weeks of taking the drug, the body has generally begun to adapt to it. Testing at this point reflects the individual's baseline health status more accurately, avoiding potential minor short-term fluctuations caused by initial drug intake, while also ensuring continuous disease control without the need to interrupt medication.

If monitoring the drug’s effects on specific parameters such as liver and kidney function or electrolyte levels, the first blood test should be scheduled around one month after starting treatment. It takes time for the drug to be metabolized and potentially affect organ function; conducting tests too early may not provide an accurate assessment of the drug's impact. Testing after about one month allows physicians to better evaluate how the medication affects internal physiological indicators, enabling informed adjustments to the treatment plan based on results.

Prior to blood testing, patients should inform their doctor that they are taking flupentixol-melitracen tablets so that the physician can interpret test results in context with the ongoing medication. If abnormal test results occur, do not discontinue the medication on your own; instead, promptly communicate with the doctor to determine appropriate follow-up actions.
