Hi,
Adderall (amphetamine and
dextroamphetamine) can stay in your system for a varying amount of time, depending on several factors such as your
metabolism, dosage, frequency of use, and individual body composition. In general, it takes approximately 3 to 4 days for Adderall to be eliminated from your body, but in some cases, it can take up to a week or longer. After one week, the drug should be completely out of your system.
However, if you have been taking Adderall for over a year at the prescribed dose of 20mg 2x/day, it may still be detectable in your urine after two weeks of discontinuing the medication. Depending on the type of urine test being used, it may be detectable for up to a month after the last dose.
It's essential to be honest with your doctor about the loss of your prescription, as withholding information can impact your healthcare and treatment plan. If you are concerned about the drug's detection in your urine test, it's best to discuss this with your doctor, as they can provide you with more accurate information and guidance.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
