Methadone Detection Window: How Long Until It's Gone from Your System?

The elimination half-life of methadone is approximately 15-60 hours, meaning it takes about 15-60 hours for half of the drug to be eliminated from the body. After 5 months of taking methadone daily, it is likely that the drug will still be detectable in your urine for several days after you stop taking it. The exact amount of time it will take for methadone to be undetectable in your urine can vary depending on several factors, such as your metabolism, hydration level, and urine pH. In general, it may take up to 10-14 days after your last dose of methadone for the drug to be undetectable in your urine. However, this timeframe is an approximation, and it is possible that methadone may still be detectable in your urine even after 10-14 days. If you are concerned about methadone being detected in your urine, it is best to consult with a medical professional or drug testing expert for personalized advice.
