I am woundering if the mediacation leaves your system buy 3 days ? Thank you...
Thank you for your question and welcome to ADHDCentral.com.
Because everyone metabolizes medication at a different rate, there is no exact answer to your question. Usually, this medication is no longer effective after approximately 4-6 hours (or longer for the extended release). Normally, it is out of your system somewhere between 2 and 4 days, but again, this is just an approximation. Each person will be different and this may be longer if you have been taking this medication for an extended period of time.
If you have questions, you should speak with your pharmacist, he or she would be better able to answer these types of questions.
