Trazodone in Modern Australian Practice: A Doctor’s Review for People Over 30

By an Australian General Practitioner

If you are over 30 and lie awake at 2 a.m., dreading the next day of fatigue, brain fog, irritability, low mood, or anxious nights, you are not alone. Millions of Australians struggle with poor sleep, depression, anxiety, PTSD, and the frustrating side effects of common antidepressants. Maybe you have tried SSRIs like fluoxetine or sertraline and found they killed your sex drive, made you feel numb, or caused nausea and weight gain. Maybe you are worried about taking sleeping tablets that leave you groggy or dependent.

There is another option that many Australian doctors are turning to: trazodone. It is not new — it has been around for decades — but it has earned a special place in modern prescribing because it treats a unique combination of problems: poor sleep, low mood, anxiety, PTSD nightmares, and even restless legs or limb movements during sleep. In my practice, I have seen trazodone quietly change lives, often when other medications failed.

Why Trazodone Deserves Your Attention

Trazodone is a serotonin modulator. Unlike SSRIs, it does more than just increase serotonin — it also blocks certain serotonin receptors, which gives it a powerful sleep-promoting effect and results in far fewer sexual side effects than fluoxetine or sertraline. For many Australians over 30, that single difference is life-changing.

Below, I will walk you through the key clinical facts about trazodone in Australia, using plain English, so you can have an informed conversation with your own doctor.

Trazodone – Typical Starting Dose in Australia

In Australia, trazodone is most commonly started at a low dose for sleep and anxiety. The typical starting dose is 25 mg to 50 mg taken at night. This low dose is often enough to help you fall asleep and stay asleep, without the heavy hangover of older sleeping tablets.

When trazodone is used for depression, the dose is higher — usually 150 mg per day, taken in divided doses after food, and gradually increased. Some patients need 300 mg or more, but this is done slowly under medical supervision. The key message: start low, go slow, and take it with food.

Trazodone in Elderly – Geriatric Considerations in Australia

Older Australians often need help with sleep, but they are also more vulnerable to falls, confusion, and drug side effects. Trazodone is frequently chosen for elderly patients because it is less anticholinergic than older antidepressants and generally gentler than benzodiazepines.

For patients over 65, I usually recommend starting with just 25 mg at night. We monitor for dizziness on standing, unsteadiness, and daytime sleepiness. Trazodone can lower blood pressure when you stand up, so hydration and slow position changes are important. If your elderly parent or partner is struggling with insomnia and agitation, trazodone may be a safer option than many alternatives — but dose adjustments are essential.

Trazodone and Nausea – Remedies That Work

Nausea is one of the most common early side effects of trazodone, especially at higher doses. The good news is that it usually settles within a week or two, and there are simple remedies:

• Take trazodone with food — a small snack or main meal reduces stomach irritation.
• Start with the lowest possible dose so your body adapts.
• Split the dose if higher doses are needed.
• Use ginger tea or ginger tablets — a gentle, natural anti-nausea aid.
• Talk to your doctor about a short-term antiemetic if nausea persists.

Trazodone – Interaction with Lithium – Monitoring

Some Australian patients take lithium for bipolar disorder or treatment-resistant depression. Trazodone can be used with lithium, but there is a real risk of serotonin syndrome — a potentially serious condition caused by too much serotonin. Symptoms to watch for include:

• Agitation or restlessness
• Confusion
• Sweating
• Shaking or tremor
• Fever
• Diarrhoea

If you take lithium and are prescribed trazodone, your doctor should monitor you closely, typically starting with low doses and reviewing you within 1–2 weeks. Never increase the dose on your own. If you develop any of the above symptoms, seek urgent medical attention.

Trazodone – Periodic Limb Movement Disorder

Periodic limb movement disorder (PLMD) causes repetitive jerking of the legs during sleep, leading to frequent awakenings and profound daytime tiredness. Many people do not even know they have it — their partner complains about the kicking. Trazodone has been used successfully in Australian sleep clinics to reduce limb movements and improve sleep continuity. A typical dose is 50–100 mg at night. If you feel exhausted despite sleeping all night, or your partner says you thrash or kick, ask your doctor about PLMD and whether trazodone might help.

Trazodone for PTSD – Clinical Use in Australia

Post-traumatic stress disorder is exhausting. Nightmares, night sweats, hyperarousal, and fear of sleep are common. In Australia, trazodone is frequently used off-label by GPs and psychiatrists to treat PTSD-related insomnia and nightmares. Doses of 50–150 mg at night can reduce the intensity of nightmares, calm the nervous system, and allow restorative sleep. Many of my PTSD patients say trazodone gave them the first full night’s sleep in years — and that sleep then helped their daytime therapy work better.

Trazodone – Interaction with Antifungal Medications

This is an important one that many patients miss. Certain antifungal medicines — especially the “azole” family — can dramatically increase trazodone levels in your body. These include:

• Ketoconazole
• Itraconazole
• Voriconazole
• Posaconazole

If you are taking an antifungal for a nail infection, thrush, or a systemic fungal infection, tell your doctor before starting trazodone. The combination can cause excessive sedation, dizziness, heart rhythm changes, and low blood pressure. Your doctor may reduce the trazodone dose, choose an alternative antifungal, or monitor you with an ECG.

Trazodone vs SSRIs (Fluoxetine, Sertraline) – Differences in Australia

Many Australians over 30 have been prescribed fluoxetine (Prozac) or sertraline (Zoloft) for depression or anxiety. These are excellent medications, but they are not perfect for everyone. The table below summarises the key differences between trazodone and SSRIs in Australian practice.

The Bottom Line: Is Trazodone Right for You?

If you are over 30 and struggling with any of the following, trazodone may be worth discussing with your doctor:

• Chronic insomnia, especially if you wake at 3 a.m. and cannot get back to sleep
• Depression or anxiety where SSRIs caused sexual problems or emotional numbness
• PTSD nightmares and fear of sleep
• Restless legs or periodic limb movements disturbing your sleep
• Sleep problems in older age where benzodiazepines feel too risky

Of course, trazodone is not for everyone. It can cause drowsiness, dizziness, dry mouth, and rarely priapism. But for the right patient, it is a genuine game-changer. I have seen it restore sleep, rebuild intimacy, and give people their energy and hope back.

Take Action Today

If you think trazodone could help you, do not suffer in silence. Book an appointment with your Australian GP or psychiatrist and ask:

“I’ve been reading about trazodone for sleep and mood. Could it be a suitable option for me, considering my history of [sleep problems/SSRI side effects/PTSD/restless legs]?”

Trazodone is a prescription-only medicine in Australia, so you will need a script. It is available as a generic at most Australian pharmacies, often at a very affordable price on the PBS or via private prescription. If your doctor agrees it is appropriate, you can collect it the same day and start with a low dose that night.

Imagine waking up tomorrow feeling rested, clear-headed, and like yourself again. That is the potential of trazodone — and the reason every Australian over 30 should know about it.
