Adderall Dosage Calculator
The Adderall dosage calculator computes the proper dose of Adderall (amphetamine) for both narcolepsy and ADHD.

What Adderall Dosage Calculator does
The Adderall Dosage Calculator on Omni Calculator estimates appropriate amphetamine doses for ADHD and narcolepsy based on patient weight, age, and indication. Users receive a suggested daily amount in milligrams, with options to select tablet strengths of 5 mg through 30 mg. The result is presented as a starting point for discussion with a healthcare provider, not as a prescription. The site frames the tool as a systematic way to explore pharmacological guidelines, supporting initial conversations about medication amounts while emphasizing that the output cannot replace professional medical advice.
