Re: Adderall half life

Just switched to Adderall IR today. My Dr said the half life of IR was 6 hours. I am not sure how long the effects should last though. And as far as getting the drug completely out of your system it depends on so many things, 1-3 days is what I have found online.

Re: Adderall half life

the d-amphetamine isomer has a half-life in the 10-11 hour range and the l-amphetamine isomer has a half-life of about 13 hours.

After several days of continuous use you will reach steady-state levels in your body (you will have a continuous, round-the-clock level of amphetamine).

Re: Adderall half life

Half-life is different than the duration of the effects. The average half life for d-l-amphetamine is 10-13 hours. Most doctors agree than an average dose will be effective for about 4-6 hours.

It takes about 10-12 half-lives for a drug to be completely out of your system. So in about 4 days it should be gone completely.

It won't show up on drug tests usually after only about 2 days of last use, since even though it's still in your system it is at such a low level it is under the cut-off for the drug testing.
