Atomoxetine duration timeline
Why Atomoxetine (Non-Stimulant ADHD Medications) is timed this way
Atomoxetine comes in immediate-release (IR) and extended-release (XR / ER) forms. IR gives a faster, shorter window — useful for late-afternoon "top-ups". XR / ER gives one-dose all-day coverage but with a slower onset.
Does dose affect how long Atomoxetine lasts?
Higher doses do not dramatically extend duration in most patients — they raise peak effect. If coverage runs out mid-afternoon, your prescriber may add a small IR booster rather than raise the XR dose.
What to do when Atomoxetine wears off early
If Atomoxetine wears off too early (focus crash by 2-3 pm on an XR), this is common and fixable — most often by adding a short IR top-up, not by escalating the XR dose. Don't self-adjust; ask your prescriber.
Factors that change how long Atomoxetine 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.
