ADHD Medication in Australia: Types, How They Work and Side Effects

In short: ADHD medications in Australia fall into two groups — stimulants (the first-line, most effective option for most adults) and non-stimulants (used when stimulants aren’t suitable or tolerated). They work by increasing dopamine and noradrenaline activity in the brain, which improves focus, impulse control and follow-through. Most are subsidised through the PBS once prescribed. Here’s how each works.

How ADHD medication works

ADHD is linked to differences in how the brain uses two chemical messengers — dopamine and noradrenaline — in the regions that govern attention, motivation and self-control. ADHD medications increase the availability of these chemicals, which is why people often describe medication as “turning down the noise” or finally being able to start and finish tasks. Medication doesn’t cure ADHD; it manages symptoms while it’s active in your system.

Stimulant medications (first-line)

Stimulants are the most effective and most commonly prescribed ADHD medications, helping roughly 70–80% of people who take them.¹² In Australia they fall into two families:

• Methylphenidate — brand names include Ritalin, Concerta, and Foquest. Available in short- and long-acting forms.
• Dexamfetamine and lisdexamfetamine — dexamfetamine (short-acting) and lisdexamfetamine (Vyvanse, long-acting). Lisdexamfetamine is a “prodrug,” converted by the body into its active form for a smoother, longer effect.

Stimulants are Schedule 8 (controlled) medicines in Australia, which is why prescribing is tightly regulated.³ Long-acting formulations are usually preferred for adults because they give steady cover through the day without frequent dosing.

Non-stimulant medications

Non-stimulants are used when stimulants cause side effects, don’t work well, aren’t suitable (for example, alongside certain heart conditions or a history of substance misuse), or as an add-on. They take longer to reach full effect — often several weeks — but provide 24-hour cover. Common options include:

• Atomoxetine (Strattera) — a noradrenaline reuptake inhibitor, taken daily.
• Guanfacine (Intuniv) — originally a blood-pressure medicine, effective for ADHD, especially where impulsivity or emotional regulation is prominent.
• Clonidine — sometimes used off-label, particularly to help with sleep and hyperarousal.

Common side effects

Most side effects are mild and settle as your body adjusts or the dose is fine-tuned. Common ones include:

• Reduced appetite and mild weight loss
• Difficulty sleeping (usually dose- or timing-related)
• Dry mouth, headache, or feeling “wired”
• A small increase in heart rate or blood pressure — which is why a cardiovascular check is done before starting

Finding the right medication and dose is a process of careful titration — starting low and adjusting with your doctor based on response and tolerability. If one medication doesn’t suit you, another often will.

How much does ADHD medication cost in Australia?

Most ADHD medications are listed on the Pharmaceutical Benefits Scheme (PBS) once prescribed for ADHD, which significantly reduces the cost. The exact price depends on the medication and whether you hold a concession card. Your prescriber and pharmacist can confirm the current PBS cost for your specific medication.

Who can prescribe ADHD medication?

Traditionally, ADHD medication in Australia was started by a psychiatrist or paediatrician. Since December 2025, appropriately trained GPs in Queensland can assess, diagnose and prescribe ADHD medication for adults under a Queensland Health authority pathway — without a psychiatrist referral for most straightforward cases. This has made getting treatment substantially faster and more affordable.

Frequently asked questions

What is the most common ADHD medication in Australia?

Stimulants are the most common, particularly long-acting methylphenidate (such as Concerta) and lisdexamfetamine (Vyvanse). They are first-line because they are the most effective for most adults.

What is the difference between stimulant and non-stimulant ADHD medication?

Stimulants (methylphenidate, dexamfetamine, lisdexamfetamine) work quickly and are the most effective for most people. Non-stimulants (atomoxetine, guanfacine, clonidine) take weeks to reach full effect but give 24-hour cover and are used when stimulants aren’t suitable or tolerated.

Can a GP prescribe ADHD medication in Australia?

In Queensland, appropriately trained GPs can prescribe ADHD medication for adults since the December 2025 reform. In other states, rules vary and a psychiatrist or paediatrician is often still required to initiate treatment.

Are ADHD medications covered by the PBS?

Yes, most ADHD medications are subsidised through the PBS once prescribed for ADHD, which reduces out-of-pocket cost. The exact amount depends on the medication and your concession status.
