This is general information about the categories of treatment, not advice about what you should take. Doses, choices and suitability are individual, depend on your history and other conditions, and are decisions for a clinician who knows you.
What is useful to have beforehand is the map: what the categories are, what each is for, and what "working" is supposed to look like. People frequently start treatment without a clear idea of what they are watching for, which makes it very hard to tell whether it is working.
Medication, in two broad families
Stimulants. The longest-established and, for most people, the most effective category. Two main molecular families, several formulations each, differing mainly in how quickly they take effect and how long they last. Effects are typically noticeable the same day, which is unusual in psychiatry and has a practical consequence: dose-finding is a relatively fast, iterative process rather than a six-week wait.
They are controlled substances. That has real implications for access — prescription rules, supply shortages in recent years, and rules around remote prescribing that have changed repeatedly and continue to change. Worth asking about early.
Non-stimulants. A smaller group working through different mechanisms. Generally slower to take effect — weeks rather than hours — and for many people less dramatic in effect, but they matter for specific situations: where stimulants are not tolerated, where there is a reason to avoid a controlled medication, where anxiety or blood pressure complicate the picture, or where cover is needed across the whole day.
Some medications used are licensed for other conditions and prescribed for ADHD on the basis of evidence and clinical judgement. Your clinician should tell you when that is the case.
What medication is realistically for
This is where expectations most often go wrong.
What it can do: reduce the cost of starting, make sustained attention on uninteresting things possible, reduce impulsive action, and — frequently the most valued effect — quiet the constant internal noise enough to think in one direction.
What it does not do: decide what to work on. Supply a system. Repair the accumulated consequences of years of missed things. Make you want to do your tax return.
The usual description from people for whom it works is not "I became a different person". It is closer to: the thing everybody else seemed to be able to do — sit down and begin — became available.
What "working" looks like is worth defining in advance with your clinician, in observable terms. Not "feeling better" but something you could notice: can start work in the morning without forty minutes of stalling; can read a page and retain it; got through a week without an unopened-letter crisis.
Side effects, in the honest version
Common and usually manageable: reduced appetite, difficulty getting to sleep if taken late, dry mouth, headache, an increase in heart rate and blood pressure that should be monitored. Some people report feeling flat or over-focused, which usually means the dose or the formulation is wrong rather than that medication is wrong.
The rebound as a dose wears off is worth knowing about in advance, because it is often mistaken for the medication not working. A few hours of feeling worse than baseline in the late afternoon is a known pattern with known adjustments.
Report side effects early rather than deciding alone whether to continue. Most are addressable by changing timing, formulation or dose, and the most common reason a workable treatment gets abandoned is a side effect nobody was told about.
Non-medication treatment, which is not the consolation prize
Structured coaching or ADHD-specific therapy. Not general talking therapy. The specific versions address the mechanics — externalising memory, making tasks enterable, building the systems that are not going to arise spontaneously. This has decent evidence behind it and works better alongside medication than either does alone, because medication makes it possible to implement a system and the system is what the medication is for.
CBT for what has accumulated. Years of near-misses reliably produce a set of beliefs about your own competence, and those beliefs do not lift when attention improves. This is often the most valuable piece for people diagnosed late.
Environmental change. Unglamorous, high-yield: making things visible, reducing choices, putting the timer outside your head, arranging work so an external edge exists. The best interventions are frequently structural rather than internal.
Treating what else is going on. Sleep, particularly. Untreated sleep apnoea or chronic insufficient sleep will undercut any ADHD treatment, and the reverse is also true. Depression, anxiety and substance use all interact. A plan that treats attention in isolation from these is incomplete.
What a reasonable plan looks like
- A specific, observable target, so it is possible to tell whether the plan is working.
- A dose-finding process, with contact built in at a few weeks rather than at three months.
- An agreement about what to report and when.
- Something non-pharmacological alongside it.
- A named answer to "what would make us change this".
The part that is yours
Whatever is started, the useful thing to have at the next appointment is a short written record from the weeks themselves: whether you took it, what changed, what did not, when the effect arrived and when it left, and anything new.
Dose-finding is a search, and a search goes much faster with data than with impressions. Six one-line notes are the difference between "I think it helped a bit" and a specific adjustment.
