Absolutely. : Adipex is phentermine, a form of amphetamine. While the clinical effect of amphetamines may last no more than a few hours, the elimination half-life, the time it takes the body to rid itself of half of the total amount, can be 10 to 13 hours. It would take up to five half-lives to eliminate all the drug from your system.
