Ambien (zolpidem) typically stays in your system for 1-3 days, depending on factors like metabolism, dosage, and frequency of use. In a drug test, Ambien is usually detectable in urine for up to 48 hours, but this can vary. It may be detectable in blood for up to 24 hours and in hair for up to 90 days. Ambien is not commonly tested in standard drug screens unless specifically requested, as it is not part of typical drug panels. However, chronic use or higher doses may lead to longer detection times. Always consult a doctor for concerns about testing.
