General preparation

  • Bring your referral, Medicare card, and any previous imaging if available.
  • Arrive 10–15 minutes before your appointment to complete forms.
  • Wear loose, comfortable clothing without metal zips, belts, or buttons.
  • Leave jewellery, watches, and piercings at home when possible.
  • Continue taking your usual medications unless instructed otherwise.

Fasting and hydration

  • If your scan uses contrast, avoid eating for 2–4 hours before your appointment.
  • Drink water to stay hydrated; clear fluids are usually fine.
  • If your scan does not use contrast, you can generally eat and drink normally.

Trazodone in Australia: A Doctor’s Practical Guide for Adults Over 30

Are you lying awake at 3 a.m., exhausted but unable to switch off? Are you tired of antidepressants that make you feel flat, foggy, or emotionally numb? Do you live with constant low mood, irritability, or anxiety that quietly erodes your work performance, your relationships, and your confidence?

As a doctor practising in Australia, I hear these concerns every week from patients in their 30s, 40s, 50s and beyond. Many have tried multiple medications that either left them sedated, gained weight, lost libido, or simply didn’t work. If this sounds familiar, trazodone is a medication worth understanding — and worth discussing with your GP.

Attention: The Hidden Cost of Poor Sleep and Persistent Low Mood

For adults over 30, the pressures are different from those of your twenties. Mortgage stress, demanding careers, caring for children or ageing parents, relationship strain, and the gradual loss of the resilience you once felt can all collide. The result is often a vicious cycle: poor sleep worsens mood, low mood worsens sleep, and daytime functioning collapses.

Many people self-medicate with alcohol, over-the-counter antihistamines, or simply push through. But these approaches rarely fix the underlying problem. What you need is a treatment strategy that addresses both sleep and mood without leaving you feeling like a zombie the next day. That is where trazodone has earned a trusted place in Australian prescribing.

Interest: What Makes Trazodone Different?

Trazodone is a prescription medication, classified as a serotonin antagonist and reuptake inhibitor (SARI). It has been used for decades and is well known in Australia as an effective treatment for major depressive disorder. At lower doses, it is also widely used to help with sleep, because it has pronounced sedative properties.

Unlike older tricyclic antidepressants or benzodiazepines, trazodone has a distinctive profile:

  • Improves sleep quality — it helps you fall asleep and stay asleep, often without the severe morning hangover seen with some sedatives.
  • Treats depression and anxiety — at higher doses, it works on mood and emotional regulation.
  • Lower risk of sexual side effects — many patients report less sexual dysfunction compared with common SSRIs.
  • Less likely to cause emotional numbing — although emotional blunting can still occur, many Australian patients report it feels less severe than with other antidepressants.
  • Not a benzodiazepine — it is not considered addictive in the same way, which is important for long-term use.

How to Take Trazodone Tablets

Taking trazodone correctly makes a significant difference to how well it works and how you feel the next day. In Australia, trazodone is available in 50 mg, 100 mg and 150 mg tablets. The dose depends on whether you are treating depression, insomnia, or both.

Purpose Starting Dose Typical Dose Key Instructions
Depression 150 mg/day in divided doses after food 150–300 mg/day; up to 400 mg/day in divided doses Increase by 50 mg every 3–4 days if tolerated. Take with food to reduce dizziness and improve absorption.
Insomnia (off-label, low dose) 25–50 mg at night 50–100 mg at night Take with a small snack; allow 7–8 hours in bed. Do not drive after taking.

Do not stop trazodone suddenly. If you have been taking it for more than a few weeks, your doctor will usually reduce the dose gradually to avoid withdrawal effects such as dizziness, nausea, and irritability.

Telehealth – Prescribing via Video Consult in Australia

One of the great changes in Australian healthcare is the rise of telehealth. If you are over 30, busy with work or family, or live in a rural or regional area, you can now have a video consult with your GP or psychiatrist and receive a prescription for trazodone without sitting in a waiting room.

During a telehealth appointment, your doctor will assess your symptoms, medical history, current medications, and any risk factors. If trazodone is appropriate, they can issue an e-script to your phone or email, which you can fill at any Australian pharmacy. Follow-up appointments can also be done remotely, making it easier to monitor your response and adjust the dose.

Trazodone – Blood Level Monitoring – When Needed

Most patients taking trazodone do not need routine blood level monitoring. The drug is generally safe at standard prescribed doses, and Australian guidelines do not recommend regular blood testing for trazodone levels in the average patient.

However, blood level monitoring may be considered in certain situations:

  • You have liver or kidney disease, which can slow drug clearance.
  • You are taking other medications that may interact with trazodone.
  • You have symptoms of toxicity — excessive sedation, confusion, irregular heart rhythm, or seizures.
  • You have not responded to treatment despite a high dose, and your doctor wants to check whether you are absorbing the drug properly.
  • There are concerns about adherence — whether you are actually taking the medication as prescribed.

In Australia, therapeutic drug monitoring for trazodone is available through major pathology providers, but it is used selectively, not routinely. Your doctor will order it only when clinically indicated.

Trazodone and Liver Function – Monitoring in Australia

Liver problems with trazodone are rare, but they can occur. Routine liver function testing is not required for every patient. However, an Australian doctor may order baseline liver function tests (LFTs) if you have:

  • Pre-existing liver disease (e.g. fatty liver, hepatitis, cirrhosis)
  • Heavy alcohol use
  • Other medications that affect the liver
  • Unexplained fatigue, nausea, dark urine, jaundice, or right upper abdominal pain while taking trazodone

If you develop symptoms of liver irritation, stop the medication and seek medical review promptly. Regular monitoring with LFTs is not needed for otherwise healthy adults on standard doses.

Trazodone – Yawning – Unusual Side Effect

One of the more curious side effects of trazodone is excessive yawning. Patients sometimes report yawning repeatedly, even when they are not tired. This is thought to be related to the drug’s serotonergic activity in the brain.

Yawning is usually harmless and tends to diminish over time. However, if it becomes bothersome or embarrassing, your doctor may adjust the dose or timing. It is not a sign of serious illness, but it is one of those unusual effects that many patients are relieved to hear is a known phenomenon.

Trazodone – Emotional Blunting – What Patients Report

Emotional blunting is a common reason people stop taking antidepressants. They describe feeling “flat,” “numb,” or “like a robot” — unable to experience joy or sadness fully. While this can occur with trazodone, many patients in clinical practice report that the effect is less pronounced than with high-dose SSRIs.

Because trazodone improves sleep and reduces anxiety, some patients actually feel more emotionally alive once their sleep is restored. If you do experience emotional blunting, it is usually dose-related. Reducing the dose, switching to a night-time-only regimen, or combining with psychological therapy can help restore emotional range without losing the antidepressant benefit.

Trazodone – Sports Performance – Effects on Athletes

If you’re an athlete or a regular gym-goer over 30, you may wonder whether trazodone will affect your training. The short answer is: trazodone is not a performance-enhancing drug. It has no anabolic or stimulant properties, and it is not generally considered an ergogenic aid.

However, its sedative effects can impair your performance if taken before training or competition. Reaction time, coordination, and concentration may be reduced, particularly in the hours after a dose. For this reason, athletes who use trazodone for sleep should take it at night only, ideally 7–8 hours before any morning training or competition.

If you are a competitive athlete subject to anti-doping rules, always check with your sports physician and your sport’s anti-doping authority. While trazodone is not classified as an anabolic agent or stimulant, individual sporting bodies may have specific regulations.

Trazodone – Depression and Suicide – Monitoring in Australia

In Australia, all antidepressants, including trazodone, carry a warning about the potential for increased suicidal thoughts, particularly in the early stages of treatment or when the dose changes. This risk is highest in young adults, but anyone starting or changing an antidepressant should be monitored closely.

For adults over 30, the risk is lower than in teenagers and young adults, but it is not zero. Your doctor will usually schedule a follow-up within 1–2 weeks of starting trazodone, and then regularly thereafter. Watch for signs such as worsening mood, agitation, withdrawal, or suicidal thoughts, and seek help immediately if they occur.

Desire: Why Australian Patients Over 30 Are Asking for Trazodone

Imagine waking up after a full night’s sleep, feeling rested rather than groggy. Imagine your mood lifting without the numbness, without the weight gain, without the sexual side effects that made you abandon previous treatments. Imagine having one medication that treats both your insomnia and your depression, prescribed through a simple telehealth consult and filled at your local pharmacy.

Trazodone offers a practical, well-established option for many Australian adults. It is not a new, heavily marketed wonder drug — it is a decades-old molecule with a strong safety record and a unique dual action on sleep and mood. For busy people over 30 who need to function at work, in relationships, and in life, that combination matters.

If you have been struggling with poor sleep, low mood, anxiety, or emotional exhaustion, trazodone may be the missing piece. But it is a prescription-only medicine, and the decision must be made with a doctor who knows your full history.

Action: Your Next Step

You don’t have to keep living in the fog of poor sleep and persistent low mood. Take action today:

  1. Book a telehealth appointment with your Australian GP or psychiatrist.
  2. Mention trazodone by name and describe your sleep and mood symptoms honestly.
  3. Ask about suitability — your doctor will check your heart, liver, medications, and mental health history.
  4. Get your e-script and collect your medication from a pharmacy near you.
