I take 25 milligrams of adderall (dextroamphetamine and racemic amphetamine) xr daily for my adhd and have been for 4 years, i want to take a break for a week how to i stop corectly.

Just stop: You can just take some days off. Adderall (dextroamphetamine and racemic amphetamine) works for a few hours after you take it, and then stops. There is no long term effect when taken as prescribed. Be sure to tell your doctor.

Taper the dose: I would strongly recommend against stopping cold turkey. Work with your doctor to gradually reduce your dose.

Wait...: ..You should ask your prescribing physician's office tomorrow if it's safe to stop or take a break, and, if so, how to go about it. It's not prudent to do so otherwise. Good luck.
