Adderall Dosage Calculator

Adderall is a prescription stimulant containing mixed amphetamine salts. Clinicians may prescribe an immediate-release formulation, often abbreviated IR, or an extended-release capsule, commonly called XR, for attention-deficit hyperactivity disorder and selected other conditions. Dose selection is individualized because response, side effects, other medicines, cardiovascular history, sleep, appetite, and coexisting conditions all matter. This calculator summarizes commonly published age- and formulation-based starting points. It is not a prescription and cannot determine whether this medicine is appropriate for any person. Unlike many pediatric medicines, Adderall is not routinely dosed by multiplying body weight by a fixed milligram-per-kilogram factor. Age and formulation establish typical starting guidance, while a prescriber gradually titrates according to benefit and tolerability. For immediate-release treatment, published labeling commonly starts children ages three through five at 2.5 mg daily and people age six or older at 5 mg once or twice daily. Extended-release guidance commonly starts children ages six through twelve at 10 mg each morning, adolescents at 10 mg each morning, and adults at 20 mg each morning. Lower starts may be chosen when clinically appropriate. The displayed maximum is a guideline boundary, not a target. A patient may respond well far below it, and some clinical circumstances require a different plan. Immediate-release doses are usually separated by several hours, while extended-release capsules are generally taken once in the morning. Taking stimulants late can worsen insomnia. Tablets and capsules are not interchangeable milligram for milligram without professional direction because their release profiles differ. Weight is collected because it is useful context for growth and monitoring, especially in children, but the calculator deliberately does not invent a weight-based dose. Prescribers monitor blood pressure, pulse, appetite, weight, sleep, mood, and symptom control. They also review interactions and the risk of misuse or dependence. Seek urgent medical care for chest pain, fainting, severe agitation, hallucinations, or other alarming symptoms. Store controlled medication securely and never share it. Use the result to understand terminology and prepare questions for a licensed prescriber or pharmacist. Confirm the exact product, schedule, and instructions on the prescription label. If a dose is missed or side effects occur, contact the care team rather than doubling or changing the next dose independently.
