Does dose affect how long Adderall lasts?
For most medications, a higher dose raises peak blood level rather than per-dose duration. Dosing frequency is calibrated to maintain therapeutic blood levels — not extended by taking more at once.
What to do when Adderall wears off early
If Adderall appears to wear off before your next dose, talk to your prescriber. Options include dose adjustment, schedule change, or switching to an extended-release form — never adjust your own schedule.
Factors that change how long Adderall lasts
- Age — older patients often clear medications more slowly.
- Kidney function — many medications are renally cleared.
- Liver function — many medications are hepatically metabolised.
- Drug interactions — CYP enzyme inducers/inhibitors can speed or slow clearance.
- Genetic metabolism variants (slow vs fast metabolisers).
- Hydration, diet, body composition.
