My daughter has been taking Ambien for a couple of years and it quit working and Medicaid no longer pays for it. She quit taking it 6 days ago. We think she is having classic withdrawal symptoms from it. How long will this last?

The half life of Ambien is 2 hours.
This means that every 2 hours, half of the previous amount of Ambien in the body disappears.
For example, if you took 10mg of Ambien at 10pm, at 12PM 5mg of Ambien will be left in your body. At 2am, 2.5mg will be left, and so forth until there is 0mg left in your body.
Most drugs are cleared from the body within 5 or 6 half-lives. In the case of Ambien this is 10 to 12 hours.
This is only an estimate however. Each individual person will metabolize drugs differently depending on things such as weight, health, age, metabolism etc.

I have been on Ambien for years. I noticed that sometimes it was not working. I went to my doctor and he put me on 20mg, which is not very common. I also noticed that generic Ambien's are so different. I picked my generic ambien from different pharmacy and I actually was falling asleep standing up. I believe that pharmaceutical companies differ dramatically on Generic's. I don't think that the main ingredent has to me matched up but to 70%. When Ambien first came out there were not generics and it worked. Now i have found a generic that works.I am on medicaid and it coveres mine, but only 30. 30 is all i need with this generic.
