If you are over 30 and find yourself staring at the ceiling while your partner sleeps, exhausted but unable to switch off your mind, you already know the toll it takes. You drag yourself through work. You are more irritable with the people you love. You have tried meditation, sleep hygiene, maybe even a standard antidepressant — but it made you feel numb, killed your sex drive, or added weight around your belly.
Many Australian adults accept this as “just stress.” As a doctor, I see it differently: untreated insomnia and low mood feed each other. The good news is that there is an older, well-studied medicine that many people have forgotten but that can work beautifully when newer drugs have failed. That medicine is trazodone.
Trazodone is a tetracyclic antidepressant with a different mechanism from the better-known SSRIs such as sertraline, escitalopram and fluoxetine. It works as a serotonin antagonist and reuptake inhibitor, but its special strength is that at lower doses it strongly promotes deep, restorative sleep. Unlike benzodiazepines, it is generally not considered addictive in the same way, and it does not usually produce the same “hangover” when prescribed appropriately.
In Australia, trazodone is a Schedule 4 prescription-only medicine, meaning your GP or psychiatrist must prescribe it. It is used mainly for major depression, anxiety with insomnia, and sometimes for sleep disturbance alone when other approaches have not worked. Because it treats sleep and mood together, it can break the exhausting cycle many people over 30 feel trapped in.
One of the most common questions I hear is: “How much is too much?” In Australia, the maximum daily dose depends on the condition and setting. For depression managed outside hospital, Australian practice generally caps the dose at 400 mg per day. For severe depression in hospital under specialist care, it can go up to 600 mg per day. For insomnia, we start much lower.
| Condition | Usual starting dose | Usual range | Maximum daily dose in Australia |
|---|---|---|---|
| Insomnia (off‑label) | 25–50 mg at night | 25–100 mg at night | Usually 100 mg at night |
| Depression / anxiety (outpatient) | 150 mg/day in divided doses after food | 150–300 mg/day | 400 mg/day |
| Severe depression (inpatient, specialist) | 150 mg/day | 300–600 mg/day | 600 mg/day |
Doctor’s note: Never adjust the dose yourself. Trazodone can lower blood pressure, especially when standing up, and higher doses require slow titration. The goal is the lowest effective dose — not the maximum.
Medication alone is rarely the whole answer. The best outcomes for depression and anxiety come when trazodone is combined with psychotherapy. In Australia, your GP can create a Mental Health Treatment Plan under Medicare, giving you rebated sessions with a psychologist. Cognitive behavioural therapy (CBT), interpersonal therapy, or mindfulness-based approaches work even better when severe insomnia is controlled.
Think of it this way: trazodone helps you sleep enough to have the energy to engage in therapy. Therapy gives you long-term skills so you may not need medication forever. This combined approach is widely supported by Australian clinical guidelines.
It is important to talk honestly about this. Trazodone, like all antidepressants, carries a prominent boxed warning in Australian prescribing information about the possible increased risk of suicidal thoughts or behaviour when starting treatment or changing the dose. This risk is highest in young people, but it can occur in any age group — including people over 30.
However, here is the full picture: untreated depression carries a far greater risk of suicide than the medicine itself. Trazodone’s sedating effect can actually reduce agitation in many patients. The key is close monitoring. Your doctor should review you within one to two weeks after starting trazodone, and you should have a clear safety plan. If you or a loved one notice sudden mood worsening, call your doctor, or contact Lifeline on 13 11 14 in Australia.
Many people over 30 worry that antidepressants will cause stubborn weight gain, especially around the belly. The evidence shows that trazodone has a low to moderate risk of weight gain compared with medicines like mirtazapine or some SSRIs. Some patients gain a few kilograms initially because improved sleep increases appetite or because they are less active due to sedation. Others lose weight because their mood improves and emotional eating decreases.
| Medicine | Weight gain risk | Sexual dysfunction risk | Sleep benefit |
|---|---|---|---|
| SSRIs (e.g. sertraline, escitalopram) | Moderate | High | Variable |
| Mirtazapine | High | Low | High |
| Trazodone | Low–moderate | Low | High |
If weight gain occurs, it is usually manageable with diet and activity. For many patients, the benefits of sleeping and feeling well outweigh a modest change on the scales.
If you are planning a pregnancy, pregnant, or breastfeeding, this is a critical conversation. In Australia, trazodone is classified as TGA Pregnancy Category C. This means that available data are limited, and the medicine may have caused or may be suspected of causing harmful effects on the human fetus or neonate without causing malformations. Those effects may be reversible.
That sounds alarming, but let me put it in context: many commonly used antidepressants are also Category C. The decision to use trazodone in pregnancy depends on the balance between the mother’s mental health and potential risk to the baby. Stopping an antidepressant suddenly during pregnancy can be more dangerous than continuing it, because severe depression and anxiety themselves harm both mother and baby. If you are pregnant or planning, see your GP and ask about a referral to a perinatal psychiatrist.
Many patients ask about travelling with trazodone. The rule in Australia, whether you are flying domestically or internationally, is simple: always keep trazodone in your carry-on hand luggage. Never pack it in checked baggage. Checked luggage can be lost, delayed, or exposed to temperature extremes that may damage the tablets.
Keep the medicine in its original pharmacy packaging with the prescription label. For international travel, particularly to countries with strict medication laws in Asia or the Middle East, carry a letter from your GP stating the medicine name, dose, and that it is prescribed for you. Tablets in blister packs do not need to be declared as liquids. Having your medication in your carry-on means you will never miss a dose, even if your suitcase goes missing.
Aboriginal and Torres Strait Islander Australians experience significantly higher rates of psychological distress, depression and chronic disease than the general population. When considering trazodone for an Indigenous patient, culturally safe care is essential.
This means involving an Aboriginal Health Worker or liaison officer where possible, using plain language, respecting traditional healing practices, and considering the whole person — family, community, and social circumstances. Trazodone may be a useful option because it helps insomnia and depression together, but it must be started at a low dose due to sedation and possible low blood pressure. Weight gain and diabetes are also important concerns, so regular monitoring is vital. The goal is always to reduce stigma and build trust, never to force medication.
If you are over 30 and tired of feeling exhausted, low, and disconnected, trazodone may offer a real way forward. It is not the newest or most fashionable antidepressant, but it has decades of clinical use, a strong sleep benefit, and a lower risk of sexual side effects than many alternatives. Combined with psychotherapy, it can help you rebuild your energy, your mood, and your confidence.
Here is what to do now:
You do not have to keep living in the fog. With the right treatment, you can sleep again, feel again, and take back control of your life.
