Medication math should be transparent and double-checked. Adderall Dosage Calculator shows the reference calculation built into this plugin, while leaving the prescribing decision where it belongs—with the clinician and current product guidance.

What this calculator does

Adderall Dosage Calculator uses Age, Indication, and Tablet strength to calculate published Adderall starting-dose reference. Where supported, it also shows Weekly dose increase, Schedule, and Selected tablet strength so the primary result is easier to check. It follows the exact field flow and engine behavior in this plugin rather than describing a different calculator with the same name. Medication calculations are reference math, not prescriptions. Indication, formulation, route, kidney/liver function, interacting medicines, allergies, maximum doses, and clinician-selected regimens can change the correct dose.

How to use it

Enter or select Age, Indication, and Tablet strength. Confirm weight units, formulation/strength, route, and dose units before reading the result. If an entry is unknown, do not substitute a guess simply to obtain a number.

How the calculation works

The tool uses the selected indication and age to choose the published immediate-release starting dose and weekly increment stored in the calculator. ADHD starts at 2.5 mg/day for ages 3–5 or 5 mg once/twice daily from age 6; narcolepsy starts at 5 mg/day for ages 6–11 or 10 mg/day from age 12. Tablet strength is used only to show a tablet-equivalent starting amount.

Example

Using the sample values prefilled in this calculator, the primary result is 5 mg/day (Published starting dose), Weekly dose increase is 5 mg, and Schedule is Once or twice daily; subsequent doses 4–6 h apart. This example demonstrates the plugin’s own calculation path; replace the sample inputs with verified values before interpreting a real result.

How to interpret the result

The result is the stored label-based starting-dose reference, not the dose a person should take. Prescription titration depends on response and adverse effects under clinician supervision.

Limitations and notes

Adderall is a controlled prescription stimulant. The label requires individualized dosing and clinical screening; the calculator shows starting-dose reference information only. It does not assess contraindications, cardiovascular/psychiatric risk, interactions, response, or whether treatment is appropriate.
