how long does ambien stay in your system
@Gin â¦.Ambien stay in your blood for up to 48 hours. if you take it every night, it will show up in your blood for maybe 72 hours. âââ. @dhruv, strange question, high dosage is like more than 20 mg, which is the maximum. Normal dosage is 10 mg.eak levels and half life of Ambien. Ambien is absorbed through the GI tract rapidly and completely. The peak level of Ambien, 200 ng/mL, is reached about 30 minutes after taking a normal dose of 20 mg. Ambien peak time for effects, is between 1.5-2 hours, and up to 4 hours for Ambien CR.
