Calculadora de niveles de Adderall en orina

Estima cómo cambia la concentración de Adderall en tu orina con el tiempo según la dosis y la vida media de eliminación

How to Use This Calculator

Enter your prescribed Adderall dose in milligrams (mg)
Input body weight for the illustrative model
Adjust the hours since your last dose
Select your metabolism rate if known (affects elimination speed)
Explore the illustrative decay curve and reference levels

This is a simplified educational model. It does not measure your urine or predict a drug-test outcome. Actual results depend on the sample, test method, timing, and individual factors.

Calculator Inputs

Dose (mg)

Common: 5-60mg

Body Weight (kg)

1 kg = 2.2 lbs

Hours Since Last Dose

Enter time elapsed since taking medication

Metabolism Rate

Affects elimination half-life: 12.0 hours

Illustrative model results

A simplified decay model, not a measured urine level or test prediction

This model is not validated to predict an individual urine concentration. Its reference lines are not universal laboratory cutoffs. It cannot tell you whether you will pass a test or infer a dose from a report. About drug-test interpretation

Model concentration

1428.6 ng/mL

Model reference band

Model ≥ 250 ng/mL

Model time to reference lines:

Reference: 250 ng/mL42.2 hours

Reference: 100 ng/mL58.0 hours

Your urine test, explained.

Understand the terms on a urine report and prepare questions for the person reviewing it.

Here for a drug test?

Pages 21–22 cover screening and confirmation, reporting cutoffs, prescription review, and why a urine concentration cannot reliably tell you the dose taken.

Most of the book covers general urinalysis: protein and uACR, blood, UTI markers, glucose, ketones, units, and comparing results. It is not an Adderall-specific guide or a way to predict passing a drug test.

Learn why a screening result and a confirmed result answer different questions.
Keep test names, units, collection details, and cutoffs in context.
Use the glossary and question prompts to prepare for a follow-up conversation.

About Adderall Metabolism

Adderall (amphetamine/dextroamphetamine) is a prescription stimulant medication used to treat ADHD and narcolepsy. Understanding its elimination from the body is important for medication management and testing purposes.

Key Facts:

Average half-life: 10-14 hours (varies by individual)
After 4–5 half-lives, a decay model retains about 3–6% of its starting amount
Urine levels depend on collection timing and sample concentration
Detection varies with the test, timing, and individual factors

Preguntas frecuentes

¿Qué se considera un nivel alto de Adderall en la orina?: Adderall es una mezcla 3:1 de enantiómeros d y l de sales de anfetamina. Se han reportado concentraciones máximas en orina de alrededor de 2,645–5,948 ng/mL tras una dosis terapéutica única. Se han observado muestras en o por encima de 500 ng/mL de anfetamina (un punto de corte confirmatorio común en GC-MS) hasta cerca de 47 horas después de la dosis. Los resultados varían según la dosis, el metabolismo, la hidratación y el pH urinario.
