About this guide
This page explains ADHD medicines in general terms to support understanding and informed conversations with a prescriber. It does not give doses or recommend specific medicines. ADHD medication requires proper assessment, prescribing and monitoring by a qualified clinician, and the stimulant medicines in particular are controlled medicines that must never be obtained informally or taken without assessment.
What they are
ADHD medicines help with the core difficulties of ADHD: trouble sustaining attention, impulsivity and restlessness. They work on the brain systems involved in attention and self-regulation. For many people with ADHD, well-chosen medication produces a substantial improvement, turning a daily struggle to focus, finish tasks and control impulses into something far more manageable, which can transform school, work, relationships and self-esteem.
They are not a substitute for the other parts of ADHD support, such as structure, strategies and, for children, parent and school approaches, but they are often a powerful part of the whole.
The main types, in general terms
There are two broad groups. Stimulant medicines are the best studied and, for most people, the most effective; despite the name, they help people with ADHD focus and feel calmer rather than more wired. Non-stimulant medicines are an alternative for those who cannot take stimulants, do not respond to them, or prefer them, though they generally work less quickly. Which is suitable depends on the person, and is a decision for the prescriber. This guide names the groups for understanding only.
What to expect
Stimulant medicines often work quickly, with effects noticeable within hours and lasting part of the day depending on the preparation, so the benefit and any side effects can be seen and adjusted relatively fast. Non-stimulants build up over weeks. The prescriber will monitor effect, side effects and, in children, growth and other measures, adjusting as needed. Finding the right medicine and approach can take some trial under guidance. Medication works best as part of broader ADHD support.
Important things to know
Medication is one part of ADHD treatment, valuable but not the whole, and the decision to use it is shared between the person (or family) and the prescriber. Stimulant medicines are controlled and must be prescribed, monitored and stored responsibly, never shared, sold or obtained informally. Tell the prescriber about other medicines and any heart or other health conditions. For children, the prescriber monitors growth and wellbeing over time.
When to seek help
If you or your child has ADHD, or you suspect it, speak with a qualified professional about assessment and the full range of support, including whether medication might help. Our ADHD guide explains the condition, and our Get Support page can help you find services.
