How long will a klonopin show up on a drug test? I'm 5 9" 150. I have a very fast metabolism and I'm in excellent shape

Not Medical Advice: Klonopin (Clonazepam) has a half life of approximately six hours, which is the amount of time it will take for your body to metabolize and excrete the medication. The body is considered to be "clean" after five half lives. So, based on the average person, it will take about 30 hours for the drug to be out of your system.There are many factors such as metabolism, body weight, etc. that ultimately determine the amount of time it will take to rid your body of the drug.

Klonopin is a prescription medication that is used to treat seizure disorders, panic attacks, and short term relief for anxiety. This medication can cause withdrawals, especially if used regularly for a long time or high doses. Withdrawal symptoms include seizures, mental/mood changes, shaking and/or stomach/muscle cramps.

A new study recently released findings that people who begin taking an anti-anxiety medication such as Klonopin, Valium, Xanax or Ativan after the age of 65 have a 50 percent greater risk of developing dementia within 15 years than people who have never taken this class of drug before.
