As a doctor practising in Australia, I see it every day. Patients over 30 walk into my surgery exhausted, frustrated, and often quietly desperate. They tell me things like:
If any of this sounds familiar, you are not alone. Chronic insomnia and low mood often travel together, especially after 30, when work pressure, family responsibilities, hormonal changes, and financial stress pile up. The good news is that there is a well-known, affordable, and effective prescription medicine that many Australians overlook: trazodone.
Trazodone is a serotonin antagonist and reuptake inhibitor (SARI). It was first developed as an antidepressant, but in modern Australian practice it is frequently prescribed at lower doses to help with sleep, especially when poor sleep is linked to anxiety or depression. At low doses, trazodone acts primarily as a sedating antihistamine-like agent and a mild serotonin modulator. At higher doses, it works more fully as an antidepressant.

| Typical starting dose for sleep | 25–50 mg at night |
| Typical antidepressant dose | 150–300 mg per day, usually divided |
| PBS listing | Yes, for major depressive disorder (see Medicare section below) |
| Availability | Prescription only – you cannot buy it over the counter |
One of the biggest fears I hear from patients is emotional blunting. Many people over 30 have either experienced or heard about antidepressants that make you feel numb, detached, or unable to cry or laugh properly. What patients report with trazodone is often different. At low to moderate doses, trazodone tends to be less likely to cause the emotional flatness that some SSRIs can produce. Many patients say they feel more like themselves, with improved sleep and calmer mood, rather than feeling sedated or emotionally switched off. Some patients do report mild grogginess the next morning, but this often improves after a few days. The key is careful dosing.
If you are over 30 and working full time, you cannot afford a medication that fogs your brain. Poor sleep already damages concentration, memory, and decision-making. Trazodone at low doses is often preferred because it does not usually cause the next-day cognitive impairment seen with some older sedatives or over-the-counter sleep aids. When sleep improves, many patients report better focus, sharper memory, and greater productivity at work. That said, if your dose is too high, you may feel sleepy in the morning. Your doctor will help you find the lowest effective dose.
Both trazodone and mirtazapine are sedating antidepressants used off-label for insomnia in Australia. But they have important differences.
| Feature | Trazodone | Mirtazapine |
|---|---|---|
| Sedation strength | Moderate, dose-dependent | Strong, especially at low doses |
| Weight gain | Less common | Very common |
| Effect on sleep architecture | Improves sleep maintenance, less effect on sleep onset | Improves sleep onset, can increase slow-wave sleep |
| Morning grogginess | Possible, usually mild | Often more pronounced |
| Emotional blunting | Less common at low doses | Less common than SSRIs, but possible |
| Best for | Sleep maintenance insomnia with mild depression/anxiety | Insomnia with poor appetite or weight loss |
In my experience, if your main problem is waking up in the middle of the night and not being able to get back to sleep, trazodone is often the better choice. Mirtazapine may be preferred if you also need to gain weight or have severe difficulty falling asleep. Your doctor will tailor the choice to you.
Many Australian adults ask me about natural add-ons. Omega-3 fatty acids, particularly EPA and DHA from fish oil, have been studied as an adjunct to antidepressants. While omega-3 is not a replacement for prescription treatment, combining a high-quality omega-3 supplement with trazodone may offer a gentle mood boost. The anti-inflammatory effects of omega-3 are thought to support brain health and may enhance the response to antidepressants. It is generally safe, but always tell your doctor about any supplements you take.
This is a major advantage. Trazodone is listed on the Pharmaceutical Benefits Scheme (PBS) for major depressive disorder. That means if you have a Medicare card and your doctor prescribes trazodone for an approved indication, you pay a PBS-subsidised price rather than the full private prescription cost.
This makes trazodone one of the more affordable options for long-term sleep and mood management in Australia.
If you are breastfeeding, this is a critical topic. Trazodone passes into breast milk in small amounts. The data on breastfeeding while taking trazodone is limited, but it is generally considered compatible with breastfeeding only if the benefits clearly outweigh the risks. The main concerns are sedation, poor feeding, or irritability in the infant. In Australia, guidelines advise caution. If you have severe depression or insomnia that is affecting your ability to care for your baby, trazodone may be considered after a careful risk-benefit discussion with your GP, obstetrician, or psychiatrist. Your baby should be monitored for drowsiness or feeding difficulties. Never start or stop trazodone during breastfeeding without medical advice.
If you are taking trazodone, you are being treated for a medical condition, usually depression or anxiety-related insomnia. When you buy travel insurance, you must declare this. Australian travel insurers ask about pre-existing medical conditions, including mental health conditions and medications. Failure to declare trazodone could void your policy if you need medical care overseas. The good news is that stable, well-managed depression or insomnia is often covered, sometimes with a small premium loading. Always declare trazodone honestly when purchasing travel insurance.
This is non-negotiable. Do not drink alcohol while taking trazodone. Both alcohol and trazodone depress the central nervous system. Combining them can cause:
Australian prescribing guidelines strongly warn against alcohol use with trazodone. If you enjoy a glass of wine after work, you will need to stop or strictly avoid alcohol on treatment days. Talk to your doctor honestly about your alcohol intake.
Trazodone is not a magic pill. But for many Australians over 30, it is a safe, effective, and affordable tool to break the cycle of poor sleep, low mood, and daytime exhaustion. It can help you feel sharper at work, less emotionally flat, and more in control of your nights.
Here is what I recommend you do now:
Do not buy trazodone from unregulated online sources. In Australia, it is a prescription-only medicine for good reason. The safest and cheapest way to obtain it is through a GP script and a registered Australian pharmacy. Your health is worth doing it properly.
