There are many factors that can affect the length and severity of Xanax withdrawal. An individual’s unique chemistry, environment, and how much and how often Xanax was used all affect a withdrawal timeline.  It is important to note that most symptoms of Xanax withdrawal can be lessened tremendously with the help of medication, in a treatment facility staffed with trained addiction professionals. A typical Xanax withdrawal timeline may look something like this:
Initial Withdrawal: 6-12 hours after the last dose was taken, symptoms of anxiety, headache, and insomnia will set in.
Peak Withdrawal: During the first few days after the last does, these symptoms will intensify along with the onset of nausea, vomiting and diarrhea. There is also a high risk of seizures during this time.
Subsiding Withdrawal: Around 1 week after the last dose, these symptoms will start to decrease, although anxiety, insomnia and depression may still be an issue.
Ending Withdrawal: After a few weeks, normal functionality may return depending on the individual. Some of the symptoms can last much longer in certain cases, which is why it is best to be treated by a trained addiction professional who can adjust treatment plans accordingly.
Withdrawal can be very dangerous, particularly the peak period.  It is important to go through this under the supervision of a trained professional in a safe environment with the appropriate medications on hand.
