Why it happened
Two things collided: global manufacturing disruptions reduced supply, while demand surged. AIHW data shows the number of patients per 1,000 on stimulant treatment nearly quadrupled between 2013-14 and 2022-23, rising from 5 to 18 per 1,000. The system was not built for this volume.
What to do if you cannot fill your script
The Australasian ADHD Professionals Association (AADPA) has published clinical guidance. Options your GP may discuss: switching to immediate-release methylphenidate (Ritalin IR), switching to dexamfetamine or lisdexamfetamine (Vyvanse), or adjusting dose timing. Do not stop medication without talking to your GP first.
Why this makes GP access even more important
People newly diagnosed and waiting to start treatment are caught between a long psychiatrist wait and a medication shortage. A GP trained in ADHD assessment who can prescribe independently, including alternatives not affected by the current shortage, is now the more practical pathway for many Queensland adults.

Which ADHD medications are affected by the shortage?
The TGA lists Concerta, Ritalin LA, Teva-XR, and Rubifen LA as affected. All are extended-release methylphenidate products. Concerta is expected to remain in shortage until end of 2026. Short-acting methylphenidate (Ritalin IR), dexamfetamine, and lisdexamfetamine (Vyvanse) are generally still available.
Can my GP switch me to a different ADHD medication during the shortage?
Yes. Your GP can discuss alternatives such as immediate-release methylphenidate, dexamfetamine, or lisdexamfetamine (Vyvanse). The AADPA has published clinical guidance on switching during the shortage. Do not change or stop your medication without speaking to your GP first.
Why are ADHD medications in short supply in Australia?
Two factors combined: global manufacturing disruptions reduced the supply of extended-release methylphenidate, and demand grew sharply. AIHW data shows the number of Australians on stimulant treatment nearly quadrupled between 2013-14 and 2022-23.
How long will the ADHD medication shortage last?
The TGA expects Concerta supply disruptions to continue until at least end of 2026. Other extended-release methylphenidate products have varying expected resolution dates. Check the TGA medicine shortage database for the latest updates on individual brands.
Can a GP prescribe ADHD medication in Queensland?
Yes. In Queensland, GPs with appropriate training can assess and prescribe ADHD medication for adults without a psychiatrist referral. This includes stimulant medications such as methylphenidate and lisdexamfetamine. Read more about GP prescribing for ADHD in Australia.
