Why This Test Might Be Ordered

Your healthcare provider may order this test if you’re taking metoclopramide to check if the medication is working as intended. It’s also used to adjust your dose if needed or to detect potential side effects, such as unusual movements or drowsiness, which can occur at higher levels.

What to Expect Before the Test

No special preparation is needed. You may have a small needle inserted into a vein in your arm, and blood will be drawn into a tube. This process usually takes a few minutes.

What the Results Mean

Results help your doctor determine if your dose is appropriate. Very high or very low levels may indicate issues like poor absorption, liver problems, or incorrect dosing.

Common Reasons for Monitoring

This test is often used in patients who take metoclopramide long-term, especially those with conditions like gastroparesis or nausea. It helps prevent excessive side effects and ensures the drug stays within safe ranges.
