My neice took approximately 2mg of a vicoprofen (hydrocodone and ibuprofen). she is on probation. how long will this stay in her system to be detected on a urine drug test.

Not medical: This site is not for answering such questions. If she took these without prescription, then I recommend that she get help for this problem as priority.

Caution: Be careful about your own enabling behavior, eg, asking this question for your niece. She needs to face consequences for her behavior through a treatment program and comply with probation. Most enablers are well-intended and think they're helping a loved one, when they may be perpetuating a problem by doing too much. Try to step back and let your niece cope. She must pick herself up. Take care.
