Question: HOW LONG DOES IT TAKE TO STOP AMBIEN SO THAT IT DOES NOT SHOW IN A URINE TEST. I HAVE BEEN TAKING 40 MG DAILY

Answered by Dr. Nsah Bernard (1 hour later)

Brief Answer: From 48 hours upward Detailed Answer: Hello, Thanks for posting your query, Ambien (generic name: zolpidem) has a half-life os 2.5 hours (with a normal liver function) and about 48-67% eliminated through urine where as 29-42% through feces. You should expect that in the next 48 hours, you should not be able to excrete any significant amounts of zolpidem in your urine (that can be detectable). If you increase intake of water and fluids, it might even take lesser time for it to clear off. If you do not wish for any traces to be detectable, it will be wise to wait for at least 1 week before the test can be conducted. Hope this helps and wish you the best. Dr. Nsah
