I am prescribed 10mg Adderall 2x a day, I take mostly on weekdays to help me with my job, sometimes i may take an extra one but i do not take on weekends/holiday/time off. I just got a new dream job and they will be doing hair test. I do have a prescription so that would not be an issue, and it would not be considered a safety risk since it is sales, my question would be: I know it will come as positive for Amphetamine, will they see that sometimes i may take more than the prescribed? Does the hair test shows that difference? I do not want them to say that i am abusing since i am not, my doctor is aware as i just dont want to go to a higher dose as my current dosage works well and lasts for the month. I am not sure how the hair test comes up and would appreciate any help!

    No, they won't be able to see that unless you're taking way more than prescribed. Nov 17, 2019 at 1:54

    I don't understand. Adderall is a controlled substance. You can't take more than what your doctor prescribes (unless you buy it from a dealer who doesn't check the prescription from your doctor). Nov 17, 2019 at 12:01

    They can only detect presence or absence. Trying to determine the exact amount you’ve taken based on hair follicle would be impossible. Nov 17, 2019 at 22:09

    Professional advice: please take your medication as prescribed, especially psychotropics. They are there to help your brain regulate neurotransmitter levels and balance brain function. Taking extra one day and not taking any for a few days can seriously screw up the effectiveness of the medication and increase risk of side effects. Nov 18, 2019 at 10:45

1 Answer 1


Ask your doctor. They may be able to change the words on the prescription. They should have an idea about what the testing will show and not-show. You will be required to bring the bottle, so make sure you get a bottle with the updated label to reflect the change in prescription if it is changed.

While you are asking your doctor also ask what will happen If they give you a urine test. You never know they could give both, or the next company might give a urine test.

  • This is the correct course of action. If you are worried about the fact you are actually taking 30 mg instead of 20 mg, you need to tell the doctor who prescribed you Adderall, that the prescribed dosage isn't enough.

    I would also add to ask generally about taking more than prescribed. I'm sure for the doctor knowing you feel necessary and helpful to have 30mg instead of 20mg in some situations will be helpful.
