Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Tramadol overdose is a serious medical emergency that occurs when someone takes too much of this prescription pain medication. An overdose can cause life-threatening complications including severe respiratory depression, cardiovascular collapse, and potentially death. Prompt diagnosis through laboratory testing is crucial for appropriate emergency treatment.
Recommended Test
Tramadol and Metabolite, Serum/Plasma
This test measures both tramadol and its active metabolite o-desmethyl tramadol in the blood. High levels of either compound can confirm a tramadol overdose. The test is essential for diagnosing overdose situations that may present with severe symptoms including respiratory depression, cardiovascular instability, severe drowsiness, cold and clammy skin, muscle weakness, fainting, or coma. Measuring both the parent drug and its metabolite provides comprehensive assessment of tramadol toxicity.
