A shortage of ADHD medicines is putting families in a serious squeeze around the country, with no relief expected for months or even years.

Parents have been pushed to sacrificing their own medication for their children, swapping prescriptions, and even traveling extensive hours in a bid to secure any part of the dwindling medicine supply.

McFadden, who is a psychologist and the host of one of Australia’s leading mental health podcasts, ADHD Mums, in addition to being a mother of three, expressed that families and individuals with ADHD have faced a significant failure in support.

She was diagnosed with ADHD at age 36, after which so were her three children, currently aged under 10.

“It was life-changing in a really positive way,” McFadden told 9news.com.au, saying she shed tears when she took medication for the first time.

“It’s mind-blowing. You realise you have been white-knuckling through life,” she said.

“I’m now parenting differently, I’m on top of things, my relationship with my husband is better.”

Her children had a similar happy experience when after a two-year wait and thousands of dollars in medical bills, they were also prescribed medication for ADHD.

It was this experience which drove McFadden to launch her ADHD Mums advocacy platform.

But then, she said, the family’s new lease on life was “ripped away” in months as the shortage hit and medicines became harder and harder to find.

The list of medicines include Concerta modified-release tablets, Teva-XR modified-release tablets, Ritalin LA and Rubifen LA capsules, and Ritalin 10mg immediate-release tablets.

McFadden said she could spend hours on a weekend calling around to check with up to 30 pharmacies for suitable medications, in some cases followed by hours-long drives.

In one heartbreaking instance, the final bottle had been sold as she travelled to the pharmacy in question, though McFadden said the business was “right” to not reserve it.

On another occasion, as she tried to get through to her doctor to send through an updated prescription so she could buy another store’s last bottle of medication, a dad entered and also asked for it, prompting an argument over who had precedence.

“He didn’t seem like a bad person or anything, he was just desperate like I was,” McFadden said.

“It was astounding – here we were fighting over a bottle of medicine, and I remember thinking, how did we come to this?”

She says the government needs to develop a “long-term plan” to face the crisis, and questioned why there was no push to manufacture the medicines in Australia.

Recently, the federal government changed the rules to permit GPs to diagnose and manage ADHD.

This has been hailed as a win for accessibility – including by McFadden – but it isn’t an answer on its own.

Psychologist and Macquarie Health Collective chief executive Tanya Forster said while the decision was a win for many, especially in regional communities, there were two central problems.

The first is the worsening GP shortage, with doctors in increasingly short supply, and facing major work overload already.

“We can’t solve one problem by worsening another,” Forster said.

The other was that broadening access to ADHD tests meant diagnoses were almost certain to rise further – which increases the pressure on a limited medication supply.

“It will take action from the government to correct the supply chain issue,” Forster said.

She said the situation was “really challenging” for families, who were already struggling to access the services they needed in the sector.

And for children, the medicine shortage is especially dire.

Forster said an early-diagnosed child with reliable access to prescribed medication was better able to absorb and learn the strategies for managing ADHD that would be “protective” as an adult.

For McFadden, it’s been devastating to watch her kids struggle with intermittent medicine supply.

“You’re told, ‘go on another type of medication’ – it doesn’t really work that way for ADHD,” she said.

She said an unreliable medicine stream meant her children could be “changing their brain function every day” – confusing and frustrating for them, as well as for their teachers and their peers.

McFadden believes part of the problem is a still-entrenched perception that ADHD medicines aren’t critical to peoples’ wellbeing.

And despite the resonance of the ADHD Mums advocacy platform, with an audience of more than one million a year around Australia, she said there was a terrible feeling that nobody who could change things was listening.

Forster said wheels “turned slowly” in government and urged parents facing difficulties in sourcing the right medicines not to stray from prescription guidelines but to contact their GP or paediatrician.

“If we are self-medicating, sharing, or rationing medications, there are risks involved,” she said.

“These are regulated medicines for a reason.”
