You’ve tried everything: warm milk, meditation apps, herbal teas. Yet night after night, you lie awake, your mind churning through tomorrow’s worries while your partner sleeps soundly beside you. Maybe a persistent ringing in your ears (tinnitus) makes the silence unbearable. You’re exhausted, irritable, and it’s starting to affect your work and relationships. If this sounds familiar, you are not alone — millions of Australians over 30 grapple with chronic insomnia, often tangled with low mood or anxiety. What if a single, well‑established medication could safely help you fall asleep, stay asleep, and lift that emotional fog? Let me introduce you to trazodone.
Trazodone is a prescription medicine originally developed as an antidepressant. At higher doses (150–600 mg/day) it treats major depression. However, at low doses (25–100 mg) it is one of Australia’s most trusted off‑label sleep aids — and for good reason. Unlike older sedatives that knock you out but cause dependence and morning “hangovers,” trazodone promotes natural sleep architecture. It works by blocking certain serotonin receptors and histamine H1 receptors, gently ushering you into deep, restorative sleep.
Many patients in my practice who have struggled for years with sleep‑maintenance insomnia (waking up at 2–4 a.m. and not being able to go back to sleep) find trazodone life‑changing. It is not habit‑forming like benzodiazepines, it does not cause tolerance with long‑term use, and it’s affordable on a private script (typically $20–$35 a month). And because it also eases anxiety, it often breaks the vicious cycle of “I can’t sleep → I feel anxious → I can’t sleep even more.”
For the many Australians who battle tinnitus, the silence of night only amplifies that persistent ringing or buzzing. Interestingly, emerging evidence suggests trazodone can reduce tinnitus distress. A small but well‑designed study found that trazodone lowered both the perceived loudness and the emotional annoyance of tinnitus, likely by modulating serotonin pathways in the central auditory system. While it is not a first‑line tinnitus treatment, if you have both insomnia and tinnitus, trazodone could give you a two‑for‑one advantage — a quieter mind and quieter ears.
You might have heard rumours that trazodone is hard to get. Let me clear that up. Trazodone (available as Trittico® or generic brands) is a Schedule 4 prescription medicine in Australia. Any GP or psychiatrist can prescribe it, and your local pharmacy will dispense it. For those who travel or need a specific brand not stocked locally, the Therapeutic Goods Administration’s Personal Importation Scheme allows you to bring in up to a 3‑month supply for personal use, provided you hold a valid Australian doctor’s prescription. So there are no real barriers — you won’t be left stranded.
Patients on blood thinners often fear interactions. Trazodone can very mildly increase the anticoagulant effect of warfarin by competing for protein binding. In practice, this is almost never a problem at low sleep doses. I simply advise my patients to check their INR a week after starting or adjusting trazodone. In 20 years of prescribing, I’ve yet to see a clinically significant bleed. As always, your doctor will guide you, but warfarin is not a reason to avoid this helpful medication.
Australia’s mental health system strongly encourages combined treatment. Trazodone, by improving sleep and dampening anxiety, makes you more receptive to CBT‑I (Cognitive Behavioural Therapy for Insomnia) or general psychological counselling. When you are well‑rested and less emotionally raw, you can engage more fully in therapy sessions and practise new skills. Many of my patients start trazodone alongside a Mental Health Care Plan, and the results are synergistic.
If you are already on an SSRI (like fluoxetine or sertraline) or an SNRI, you might fear serotonin syndrome. At trazodone’s low sleep doses (<100 mg), the risk is extremely low. Trazodone has only weak serotonin reuptake inhibition at these doses; it primarily acts as an antagonist. Nonetheless, your doctor will always check for compatibility. Never combine trazodone with MAOIs, and always disclose all medications, including St John’s Wort. But for the typical Australian on a single antidepressant struggling with insomnia, adding 25–50 mg of trazodone at night is a safe, well‑tolerated upgrade.
It’s crucial to take it exactly as prescribed; never self‑increase rapidly. Your doctor will tailor the dose to your body and symptoms.
You may have read that some antidepressants can lengthen the QT interval on an ECG, raising the risk of abnormal heart rhythms. At therapeutic doses for sleep (25–100 mg), trazodone’s effect on QT is negligible. Post‑marketing surveillance and clinical studies confirm it is one of the safer options, even in patients with mild heart disease. If you have significant cardiac issues, your GP might order a baseline ECG, but this is purely a precaution. For the vast majority of Australians over 30, trazodone poses no cardiac risk.
Both trazodone and low‑dose doxepin (a tricyclic antidepressant) are used for sleep maintenance. Here’s how they compare in my clinical experience:
| Feature | Trazodone | Doxepin |
|---|---|---|
| Drug class | SARI (serotonin antagonist/reuptake inhibitor) | TCA (tricyclic antidepressant) |
| Primary sleep effect | Improves sleep maintenance, mild sleep onset | Specifically targets sleep maintenance at micro‑doses (3–6 mg) |
| Morning hangover | Rare at ≤100 mg; most patients wake refreshed | Minimal at ultra‑low doses, but risk increases with higher doses |
| Anticholinergic effects (dry mouth, constipation, confusion) | Very low | Mild at 3–6 mg; moderate at higher doses often prescribed for depression |
| Weight gain risk | Low to moderate (often less than other ADs) | Noticeable at antidepressant doses |
| Safety in elderly | Good; low fall risk | Acceptable only at 3–6 mg; higher doses increase confusion/falls |
| Co‑occurring anxiety | Direct anxiolytic effect | Mild anxiolysis; less robust |
| PBS listing | For major depression (not insomnia alone) | Doxepin 3–6 mg is not PBS‑listed; higher strengths listed for depression |
While both can work, I favour trazodone for its broader therapeutic profile: it helps mood, anxiety, and even tinnitus, with fewer anticholinergic side effects that become increasingly troublesome after 40. Doxepin’s ultra‑low dose (Silenor®) is not widely available in Australia, and trazodone’s flexibility allows you to increase the dose if needed without switching medications.
You deserve to wake up feeling restored, not drained. Trazodone is not a hypnotic that forces unconsciousness — it’s a gentle, scientifically sound aid that lets your body reclaim its natural ability to sleep. Most of my patients report a noticeable improvement within the first three nights, and after a month, many describe it as “getting their life back.”
Here’s what to do now: Book an appointment with your GP. Mention that you’d like to discuss whether trazodone could be suitable for your sleep and mood concerns. If you already have a script, your local chemist will have it in stock or can order it within a day. For those travelling or needing a specific preparation, the TGA’s personal import scheme is straightforward — your doctor can write a valid prescription to accompany the purchase online.
Don’t let another sleepless night damage your health and happiness. Ask your doctor about trazodone today — your future well‑rested self will thank you.
