A member asked:

Could adderall (dextroamphetamine and racemic amphetamine) xr lose potency over time?

A doctor has provided 1 answer

Not usually: Once an appropriate dose is reached to control symptoms a patient can stay at that dose for years. If the environment becomes more stressful, demanding or chaotic, an increase in dosage may be necessary, however.
