A ketamine-derived nasal spray improved Alexis' depression. It's being added to the PBS
Thousands of Australians could be eligible to receive the nasal spray, called Spravato, which contains esketamine, at a subsidised rate through the Pharmaceutical Benefits Scheme (PBS) from 1 May.
It's the first medicine to be PBS-listed specifically for treatment-resistant depression and will cost $31.60 per dose, or $7.70 for pensioners and concession holders.
The medication is chemically similar to ketamine and would be offered to people experiencing treatment-resistant depression, like 34-year-old youth mental health researcher Alexis Hutcheon.
Hutcheon started using the spray in 2022 after years of "frustrating" failed attempts with oral antidepressants.
Hutcheon's journey with Spravato
Hutcheon said her depression largely manifested as physical symptoms like gut issues, sleeping problems, and losing a lot of weight. It got to the point where she struggled to walk to the front door, let alone leave the house.
"I was that depressed that my body was experiencing such horrible physical symptoms due to my deteriorating mental health," she told SBS News.
Hutcheon went through years of trying oral antidepressants with limited to no success.
"Some of them worked for a little bit, and then they didn't, and some of the side effects weren't something that I could handle, like no sleeping," she said.
"If it doesn't work, you get this feeling like you want to give up, or you feel like it's your fault."

Allan says no depression treatments worked for him. Then he tried ketamine
Hutcheon first tried Spravato during a clinical trial in 2022 and noticed positive changes almost "straight away".
"I was always waiting for the moment where it stopped working, but it's been a number of years now, and things have improved and improved," she said.
"Things haven't gone back to as bad as they were at all since I started using ketamine."
How Ketamine works for treatment-resistant depression
Ian Hickie, the co-director of the Brain and Mind Centre at the University of Sydney, has been working with patients who take Spravato.
He told SBS News its PBS listing marks a "significant advance".
"It's a really different compound to the available antidepressants we've had over recent years," he said.

Hickie explained it's the first PBS-supported drug that targets a different chemical in the brain called glutamate.
"Internationally, about half the people with treatment-resistant depression demonstrated a significant improvement with this drug," he said.
"In trials, I've personally been associated with in Australia, we have found the same thing in specialist clinics here."
He said many patients have experienced a significant improvement in their quality of life, but cautioned it can cause some to feel "disoriented, disassociated, or quite unusual".
Strict clinical regulations
Ketamine therapy, along with other forms of treatment like psychedelic-assisted therapy, is highly regulated and is done in strict clinical settings.
Studies have shown low doses of oral ketamine can treat post-traumatic stress disorder, and in tablet form, can reduce the symptoms of severe depression.
These therapies are administered in hospitals and clinics under medical supervision.
"You're in your own room and you're there for an hour and a half to two hours monitored by a clinician throughout the whole time," Hutcheon said.
Hickie said the cost of attending clinics can be hundreds or even thousands of dollars, which can create a barrier for people wanting to try the nasal spray.
"The cost of medical specialist care generally in Australia is very high, and that has meant access to these compounds to be difficult," he said.
He said many mental health treatments are only offered privately, and he would like public hospitals to "step up" and provide the "novel" treatment.
Despite the availability of ketamine therapy, illicit use of the drug is on the rise in Australia.
Use of illicit ketamine on the rise
A national survey of 740 people who regularly use illicit stimulants found over half had used non-prescribed ketamine.
Fifty-three per cent of those surveyed last year used the drug, up from 49 per cent the year before, according to the University of New South Wales' Drug Trends program.
The group releases annual surveys of hundreds of people who use illicit drugs living in each of Australia's capital cities.
Dr Rachel Sutherland, lead of the Drug Trends program, said use of illicit ketamine was "infrequent" in a survey report for 2024.
"It is important to note that most participants who had used ketamine reported infrequent use [i.e., less than monthly], although approximately one in 10 reported weekly or more frequent use," Sutherland said in the report.
Hutcheon said there is more to do to help people access therapeutic ketamine.
"Seeking help can be difficult, especially due to stigma.
"Even though PBS-listing is one step forward, which we're so happy for, there will still be a number of people who won't be able to afford those private fees that occur to actually have the medication."

PFAS experts answer common questions about 'forever chemicals' and the risks to human health
PFAS, it seems, are everywhere. From farmers in Queensland managing contaminated land, to residents north of Perth fighting for tainted pipework to be replaced, Australians are grappling with how to live with so-called "forever chemicals". Last week, a New South Wales Health expert advisory panel delivered its report on the health impacts of PFAS, on the same day researchers confirmed 21 new PFAS chemicals had been detected in Sydney's tap water. With a Senate inquiry into the extent, regulation and management of PFAS looming, some academics are encouraging a rethink on the essential use of these substances. To better understand how "forever chemicals" work, what the risks are, and what's being done to address the problems, we sat down with three leading PFAS experts: These researchers, who have a combined six decades of experience in the fields of environmental science, engineering and molecular toxicology, are urging caution around what they've called a growing problem. Have you got a question about PFAS? Dr O'Carroll will join us live from 11am to answer the common questions about forever chemicals. Per- and polyfluoroalkyl substances (PFAS) refers to a group of over 14,000 synthetic chemicals used in all sorts of industrial and domestic products since the 1950s. They're often used in firefighting foams, pesticides, building materials and electronics, as well as household products such as stain-resistant upholstery, waterproof clothing, cleaning products, cosmetics, food packaging and non-stick cookware. Dr O'Carrol explains that the chemical properties of PFAS make them very effective at repelling water, oil and dirt. "It's a chemical that likes to be at interfaces … it doesn't let water through jackets, doesn't allow wine to stain our carpets," he says. Dr Clarke adds "anything that is advertised as oil- or water-repellent is likely to have a PFAS in it". "It has a carbon-fluorine bond, which is very strong, and it doesn't degrade easily in the environment … they get the term 'forever chemicals' because they don't really degrade," he says. The durability of PFAS means they can persist in the environment — and in the bodies of humans and animals — for a long time, and this presents significant concerns. According to the latest National Health Measures survey, most Australians have detectable levels of PFAS in our blood. The most common types detected are perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorohexane sulfonic acid (PFHxS), found in more than 85 per cent of the population. The Australian government's PFAS taskforce notes these chemicals aren't directly manufactured in Australia, but we do know they are found in products we use and traces have been found in the environment. Dr DeWitt says most people are exposed to PFAS through ingestion — the water they drink or the food they eat. Pioneering research by Dr O'Carroll, in collaboration with international scientists, tested 45,000 soil and groundwater samples from around the world, and found "a substantial fraction" had PFAS levels exceeding safe drinking water guidelines. The highest PFAS levels tended to be around known exposure sites, including training areas where firefighting foam had been in high use, or around landfills. Levels of PFAS have also been detected in water filtration plants in Sydney, in compost being sold to the public in Western Australia, and in the nesting soils of little penguins around Tasmania. Last year, Australia updated its guidelines around safe drinking water to reduce the accepted levels of several PFAS chemicals. Dr DeWitt says less is known about other routes of exposure, such as skin absorption or inhalation. "But we know that when PFAS are [ingested in food or drink] the bulk of what you take into the body can get absorbed across your intestines and get into your blood," she says. Dr DeWitt says once PFAS are distributed throughout the body, they can cross cell membranes and interact with proteins that affect various bodily functions. "Some of these proteins can affect vitally important processes in our bodies, such as the production and action of hormones, the production of cholesterol. So they can interact with these physiological proteins in the body to produce toxicity," she says. Researchers say one of the biggest concerns with PFAS is their persistence — that is, how long they hang around in our bodies. "Many PFAS get excreted in the urine, so they travel from the blood to the kidneys, where they can get pushed out of the body whenever somebody urinates," Dr DeWitt says. But this can take a long time. For some PFAS, the half-life — that is, the time it takes for half of the amount ingested to be excreted — is a matter of hours or days, but for most, it's years. "The problem is, even if you have low levels of exposure, you can still build up amounts in your body if what you rake in is greater than what you put out," Dr DeWitt says. The science on PFAS and the potential impact on human health has been the subject of much public debate in the past few years. Not all of these 14,000 chemicals have been closely studied. Most research has focused on the effects of well-known PFAS, often in populations who have been exposed to high doses. From that research, PFAS exposure has been associated with increased levels of cholesterol and uric acid in the blood, reduced kidney function, altered immune function and levels of thyroid hormones, delayed menstruation, earlier menopause and lower birth weight. The Australian Health Department's PFAS guidelines note these differences have generally been small and unlikely to cause significant negative health outcomes. And less is known about the toxicity of these chemicals at low doses over time. However, Dr DeWitt notes several large-scale epidemiological studies of people who have been highly exposed to PFAS have led to some concerning findings. "Right now, PFOA has the strongest evidence of links to cancer, followed by PFOS. For the others, there haven't been enough studies to understand if they are linked to cancer," Dr DeWitt says. "But we also have evidence from experimental studies with animals like mice and rats to support what we observe in exposed people, which gives biological plausibility or credibility to those findings in people." The NSW Health advisory panel's report on PFAS, published last week, concluded that "health effects of PFAS appear to be small", and cautioned authorities to "avoid using currently available epidemiological studies to derive threshold levels due to the higher risk of bias". Dr Clarke warns that while more research is needed, there are potential risks we should be mindful of. "We know that there's a lot of harm from particular types of pollutants, so I'm talking about cancers, reproductive health problems, impaired immune systems, and neurological damage. "We've seen a 50 per cent decline in male fertility over the last century, which many researchers believe is associated with exposure to chemicals." In a group of more than 14,000 chemicals, not all PFAS are the same. Researchers use several criteria to evaluate the harm of different PFAS chemicals, including how persistent they are in the environment, whether they accumulate in the bodies of humans or animals, and whether they produce toxicity. The bulk of the research to this point has focused on the impact of what are known as longer-chain PFAS, including PFOA, PFOS and PFHxS. The structure of these long-chain PFAS is understood to play a significant role in toxicity, and they are generally highly mobile in water, which means they can travel long distances in the environment. Certain long-chain PFAS, such as those used in firefighting foams, have been phased out around the world and Australia introduced a ban on PFOA, PFHxS and PFOS in July. But Dr DeWitt warns that PFAS with shorter carbon chains may still be harmful. "A short-chain PFAS is as equally persistent in the environment as a longer-chain PFAS. So whether a PFAS has eight carbons or four carbons, it doesn't break down," she says. "The difference is that the shorter-chain PFAS tend to get excreted more rapidly from the bodies of living organisms … that does mean that they have a lesser opportunity to interact with molecules in our bodies to produce toxicity, but they can still produce toxicity." Dr Clarke says there's still a lot we don't know about newer PFAS, including their effects on our bodies or the environment. "But we can reasonably predict that they will be persistent [in the environment] because of that perfluoro–carbon bond, which is very strong," he says. "So [while] we don't have full scientific evidence to demonstrate that it causes an environmental harm, we can reasonably predict that it will, because it has similar properties to things that we've already banned or phased out." Dr DeWitt wants the conversation to focus on what we really need PFAS for, and to consider limiting our use to chemicals that are "essential for the health, safety and functioning of society, and for which there are no alternatives". "So, do you have to have a sofa in your house that has a stain-resistant coating? Is it really that difficult to remove stains with soap and water?" she says. "Do you have to have PFAS in your dental floss so that it glides perfectly between your teeth? "I think we need to think about the essentiality of chemicals before we put them in products." The experts say, while products like non-stick cookware and cosmetics are not thought to be a major pathway for PFAS to get into the body, there are still choices you can make to reduce exposure. "The teflon pan isn't really thought to be an exposure source to people … be mindful about how you use it, though. If you're burning it, and you see smoke coming off it, that's a sign that you shouldn't be using it at that temperature," Dr Clarke says. As for cosmetics and personal care products, if you want to avoid PFAS, check ingredients lists for any chemical with "perfluoro" in the name.

Feeling depressed or out of sorts after the weekend? You could have 'social apnoea'
It's common to feel tired and apprehensive on a Monday morning, and that can be especially true after a big weekend. New research has mapped how people's quality of sleep changes throughout the week, and has found patterns between fatigue and behaviour. It's estimated around one billion people worldwide have obstructive sleep apnoea (OSA), a condition that impacts their quality of sleep. Australian researchers have found this underlying condition is more prevalent on weekends than on weekdays, and they have labelled this phenomenon — 'social apnoea'. It can affect anyone, even if you don't typically show symptoms of OSA during the week. So why is that the case? 'Social jet lag' Professor Danny Eckert, a sleep health expert from Flinders University, was one of the lead researchers in the study that was published in the American Journal of Respiratory and Critical Care Medicine. He described social apnoea as a kind of "social jet lag", a feeling that can arise after the weekend, when our behaviours often differ from those on weekdays. "We know that people who smoke tend to smoke more on the weekend. We know that people who drink tend to drink more on the weekend," he told SBS News. "They are two sort of lifestyles or social factors if you like, that are very influential in the way we sleep and breathe." Eckert said another key change in weekend behaviour is that our sleep patterns often change, which can cause problems with our sleep quality and overall mood. People who sleep in on weekends were found to have a 50 per cent higher risk of developing a sleep disorder, according to the study. "Our circadian rhythm, or our body clock, is slow to move; it takes several days to adjust," he said. "So if we suddenly change our sleep timing, and we've all experienced this at different times with jet lag and these kinds of things, we're sleeping out of whack from what our body wants us to." What are the long-term effects? Weekend surge in sleep-disordered breathing may heighten the risk of serious health conditions, according to the research. This includes heart disease, depression, dementia, and extreme fatigue. The research found people under 60 and males were two groups more likely to suffer from social apnoea. While the exact reason is unclear, Eckert said it's likely due to behavioural factors. "We know that men tend to be drinking more alcohol than women and perhaps they're having later nights and going to sleep after women," he said. "We also know that men get sleep apnoea more, so they are more prone to 'social apnoea' in the first place." Eckert said beyond seeking clinical treatment for sleep apnoea, there are some lifestyle changes you can make to combat social apnoea. In particular, going to bed and waking up at consistent times can help establish a healthier sleep pattern. "If people are feeling tired during the day, having some trouble staying asleep, or maybe they are waking up with morning headaches, maybe they're being told that they snore loudly; these are all warning signs that you may have sleep apnoea, and it's worth having a conversation with your GP."

'It pulled me out of the darkness': Channel 10's Barry Du Bois says the words 'I'm not okay' helped save his life, and could save countless others
Barry Du Bois has weathered more storms than most- the death of his mother, a debilitating back injury, years of unsuccessful IVF, the loss of a pregnancy, his wife Leonie's cervical cancer diagnosis, and his own battle with an incurable blood cancer. But Channel 10's The Living Room co-host says one of the most important lessons he's learned through it all is the power of a few simple words: "I'm not okay." "My mental health unravelled after those years of heartbreak," Du Bois told "I spiralled into a very lonely, low place. I even contemplated ending my life. But a friend encouraged me to open up - and that conversation pulled me back." At 65 years old, Du Bois is living with multiple myeloma, a rare and incurable type of blood cancer. He was initially diagnosed in 2010 with solitary plasmacytoma, another rare form of blood cancer. This diagnosis progressed to myeloma in 2017, a condition that impacts the immune system while attacking the bone marrow. Eight years later, he continues to defy the odds, and he's using his platform to inspire others to speak up before they hit crisis point. "I know personally, when you realise that people will support you, that's when your journey out of that darkness starts to happen," he said. That philosophy is why Du Bois has joined the Heart on My Sleeve "I'm Not Okay" campaign, founded by mental health advocate Mitch Wallis. The initiative urges Australians not to wait to be asked if they're struggling. Instead, they're encouraged to put their heart on their sleeve, literally, and say it out loud. Alongside Du Bois, the campaign's ambassador line-up includes world champion surfer Layne Beachley, TV host David Koch, NRL star Kieran Foran, actor Sharon Johal, ironman Guy Leech, Gogglebox's Jad Nehmetallah, entertainment reporter Richard Reid and journalist Antoinette Lattouf. The father-of-two, who is also a proud ambassador and board member of R U OK? Day, said his work with Heart on My Sleeve is "incredibly complementary". "I think (the campaign) really complements what I do at R U OK? Day," he said. "One encourages people to check in on their loved ones and the other encourages people to speak up. Really, it's all about strengthening society and understanding the value of emotion, the positive and the negative, and not being afraid to share the tough stuff." Du Bois admitted that was not something he learned growing up. "I was raised not to show your emotions, and that took me to a very, very dark place," he said. "So now I'm incredibly passionate about telling people that they can be brave enough to show their emotions." As the proud father of 13-year-old twins, Bennett and Arabella, he's determined they'll always feel "heard". "So many children, in the busy lives that we have today, don't feel heard by their parents," he said. "The first reason is that parents often… speak in a solution-based conversation. "They see that there's a problem and the parent wants to solve it. "And when you've got a child that craves autonomy or craves independence… You telling them what they should do doesn't help." Instead, he says, parents should create conversations "where you're both learning something". Without that, kids may look elsewhere, often to social media, for validation and connection. From his own experience, Du Bois knows that perspective matters- not just for kids, but for carers. Supporting Leonie through her cancer battle gave him a new understanding of the toll it can take. "When you're a carer, you're going through something that's called borrowed trauma," he said. "You're dealing with the trauma of others as well as your own trauma, and it's really important to make sure that we get some reprieve from that. "We have to make sure our personal cup of empathy is full. We need to care for ourselves so that we can care for others." Looking back, he admits: "I refused to share the emotion and pain I was in. I sort of resented caring for myself because I believed others needed it more. But that's just not a balanced way to think." And for those facing their own illness or cancer battle, Du Bois has a simple message. "So often in this world, particularly in the medical industry, they do give up as a number, but we're not," he said. "Never give up believing there's an opportunity to do better. "Be curious about every possibility there is- new treatments, lifestyle changes, support networks. We're not defined by the diagnosis we have today, but by how we get up and thrive after it." For Du Bois, joining I'm Not Okay is another step in what he calls putting "grains of sand" in front of the wrecking ball of mental ill-health- small but vital acts of advocacy and connection. "I believe, as a modern day elder (that's how I describe myself these days) it's our duty to be as curious and to be as aware on how we can how it can improve society and how we can strengthen society," said. "Because if we're vigilant to constantly change for the better society, that means my children will have a place where they'll be able to thrive and where they will have their best opportunities."
