Does imodium show positive drug test?

Imodium is an opiod anti-diarrheal med, the active opiate is loperamide. It can certainly cause a positive result for opiates on a drug screen. However, with any drug screen, you should list all medications taken in the previous month. When a drug screen is positive, it is then sujected to a much more sophisticated test called a mass spectroscopy-gas chromatograpy test, or an immunoassay test, both of which identify the specific molecule, ie,they clearly identify the exact drug. These tests would not confuse loperamide with, say, heroin. It is like fingerprints- it gives an exact identification of the drug. If loperamide is specificallyfound in the drug test and you listed this med, the test would be reported as negative. Since loperamide is available over the counter (no Rx needed) in the U.S., and assuming there is not a large quantity in the drug test, is islikely that the test would be reported as negative anyway, but this is not a given.
