Initial Instructions, Warnings And Daily-Life Integration

Read this before using trazodone.

Trazodone is prescription only and must be used as directed by your prescriber and pharmacist.

Do not take trazodone if you have known hypersensitivity to it or any excipient.

Do not take trazodone after a recent myocardial infarction or during acute alcohol or CNS‑depressant intoxication.

Very rare but serious reactions include priapism, dangerous arrhythmias, serotonin syndrome and hyponatraemia (SIADH).

If you develop chest pain, breathing problems, severe fainting or a prolonged painful erection seek urgent care or call 999.

Avoid alcohol while taking trazodone because it increases sedation and respiratory depression risk.

Be cautious with driving or using machinery until you know how it affects you due to sedation, dizziness and orthostatic hypotension.

Store trazodone tablets in the original pack at room temperature between 15–30°C and keep out of reach of children.

Practical tip: nominate one pharmacy for repeat prescriptions and request a pharmacist counselling session on first dispense.

Use this checklist as a quick-reference card you can keep in your wallet.

• Prescription only — follow prescriber instructions.
• Absolute exclusions: hypersensitivity, recent MI, acute alcohol/CNS depressant intoxication.
• Watch for priapism, arrhythmias, serotonin syndrome, hyponatraemia.
• Seek urgent care or 999 for chest pain, breathing difficulty, fainting or prolonged erection.
• Avoid alcohol; store 15–30°C; keep away from children.
• Nominated pharmacy and pharmacist counselling recommended.

Everyday Use & Best Practices

Morning Vs Evening Dosing

When are you worried about daytime sleepiness or sleepless nights?

Typical starting doses for depression are 75–150 mg per day in divided doses, while many UK clinicians use 25–100 mg at bedtime for insomnia as an off‑label approach.

Aim to take the sedating dose at night to reduce daytime drowsiness.

If you feel sleepy during the day, shift the larger dose to bedtime and take the smaller daytime dose if you are on twice‑daily dosing.

For sleep‑focused use, take trazodone immediately before bed and expect sedative onset within 30–90 minutes.

Taking With Or Without Meals

Will food change how quickly trazodone helps you sleep?

Trazodone absorption can be affected by food.

A heavy evening meal may delay onset, so take the sedating dose with a light snack if you need faster sleep induction.

Avoid large alcohol‑containing meals or drinks as they increase sedation risks.

Practical Daily Tips:

• Set a phone alarm for dosing times.
• Keep a simple medication chart with dose and time.
• Note side effects in a diary for your GP or pharmacist review.
• Carry a wallet card listing dose, prescriber and emergency warnings.

Immediate-Release Versus Extended-Release

Safety Priorities

Who Should Avoid It

Who should not take trazodone according to MHRA cautions?

Do not start trazodone if you have a known allergy to it or have had a recent myocardial infarction.

Do not use trazodone during acute intoxication with alcohol, hypnotics or other CNS depressants.

Use caution and specialist advice if you have significant cardiac disease because of arrhythmia and QT‑risk concerns.

Also use caution with angle‑closure glaucoma, seizure disorders, bipolar disorder and severe hepatic or renal impairment.

Activities To Limit

Which activities should you avoid until you know how trazodone affects you?

Do not drive, cycle or operate heavy machinery until you know the effects due to sedation and dizziness.

Avoid tasks requiring alertness if you feel drowsy, dizzy or lightheaded because trazodone can cause orthostatic hypotension.

Monitoring And Red Flags:

• New or worsening chest symptoms or palpitations — contact GP or A&E.
• Severe fainting or ongoing dizziness — seek urgent review.
• Prolonged or painful erection — attend A&E immediately for priapism.
• Severe confusion, sudden mood changes or suicidal thoughts — contact GP, NHS 111 or A&E.

Pharmacy Safety Step:

• Ask for pharmacist counselling on interactions and side effects at first dispense.
• Report severe adverse events via the MHRA Yellow Card scheme; pharmacists can assist.

Dosage & Adjustments

General Regimen

What dose will my GP usually start with for depression?

For major depressive disorder the usual starting dose is 75–150 mg per day in divided doses with upward titration to effect.

Outpatient maximum adult doses commonly reach 400 mg per day while inpatient specialist care may use up to 600 mg per day.

Review response at 2–4 weeks and, for depression, continue therapy for at least six months after remission.

Special Cases

How should dosing change for older people or those with comorbidities?

Elderly patients should start low, often around 50 mg at bedtime if used for sleep, and titrate slowly while monitoring for falls, confusion and hyponatraemia.

In hepatic or renal impairment start at lower doses and titrate slowly because of possible accumulation.

Children: safety and efficacy are not established and routine use is not recommended.

Missed Dose And Overdose

If you miss a dose take it when you remember unless it is almost time for the next dose and do not double up.

In suspected overdose seek immediate medical help; symptoms can include drowsiness, vomiting, cardiac arrhythmias, respiratory depression, priapism and seizures.

What’s Inside & How It Works

Ingredients Overview

What is trazodone made of and which strengths are common?

Trazodone hydrochloride is supplied as immediate‑release tablets commonly in 50 mg and 100 mg strengths.

Extended‑release and prolonged‑release formulations are available in 75 mg, 100 mg and 150 mg strengths depending on the brand.

Excipients vary by manufacturer so check the patient information leaflet if you have allergies.

Mechanism Basics Explained Simply

How does trazodone improve mood and cause sedation?

Trazodone works by inhibiting serotonin reuptake and antagonising 5‑HT2 receptors.

This dual action can improve mood and produce sedative effects that clinicians often use for sleep.

Its ATC classification is N06AX05.

Additional antihistaminic and alpha‑adrenergic blockade contribute to sedation and orthostatic blood pressure effects.

Main Indications

Approved Uses

What is trazodone licensed for?

Trazodone is approved and widely marketed for major depressive disorder.

It is prescription‑only and commonly used by psychiatrists and GPs for depression.

Off-Label Uses In UK Clinics

How do UK clinicians use trazodone off‑label?

Low‑dose trazodone is frequently used off‑label for insomnia because of its sedating properties, typically 25–100 mg at night for short‑term sleep problems.

Longer or higher‑dose use for insomnia should be monitored and considered alongside non‑drug approaches such as CBT‑I.

For depression review at 2–4 weeks and continue treatment for at least six months after remission.

Indication Checklist:

• Major depressive disorder — licensed indication.
• Insomnia — common off‑label use at low bedtime doses.
• Titrate and review regularly; consider psychological therapies alongside medication.

Interaction Warnings

Food Interactions

Can tea, coffee or alcohol affect trazodone?

Avoid alcohol while taking trazodone because it increases sedation, respiratory depression and fall risk.

Caffeine will not counteract trazodone sedation and may worsen sleep when taken late in the day.

Drug Conflicts

What medicines should not be mixed with trazodone?

Combining trazodone with other serotonergic drugs such as SSRIs, SNRIs, tramadol and some triptans increases the risk of serotonin syndrome.

There is interaction potential with other CNS depressants and certain antiarrhythmics due to QT and arrhythmia risk.

Hepatic enzyme modulators can alter trazodone levels so check for drug interactions with the pharmacist.

Bring a checklist of current medicines, OTCs and herbal remedies to every appointment so the clinician and pharmacist can check interactions.

Latest Evidence & Insights

Key UK & EU Studies 2022–2025

What do recent reviews say about trazodone?

Recent UK and European guideline reviews through 2022–2025 have reappraised sedating antidepressants for insomnia and antidepressant choice.

Evidence supports trazodone’s efficacy for depression, while high‑quality randomised trial evidence for routine primary insomnia treatment is limited and mixed.

Practical Interpretation

How should clinicians use this evidence in practice?

Use trazodone as part of a wider, evidence‑based plan that includes psychological therapy and sleep hygiene.

Offer CBT‑I where available and reserve medication for targeted short‑term treatment or where insomnia coexists with depression.

Seek specialist input for higher doses, treatment‑resistant depression or complex polypharmacy.

One-Page Evidence Summary:

• Trazodone: effective for depression; off‑label insomnia use supported by clinical experience but limited RCT evidence.
• Prefer short courses for primary insomnia; combine with CBT‑I when possible.
• Keep up to date with NICE and MHRA guidance for new safety signals.

Alternative Choices

NHS Prescribing Alternatives

What else might be offered instead of trazodone?

Common NHS alternatives for depression include SSRIs such as sertraline, escitalopram and fluoxetine.

For insomnia or depression with sleep disturbance, mirtazapine or low‑dose doxepin may be used to take advantage of sedating properties.

CBT for insomnia is an effective non‑drug option available through NHS services and IAPT where offered.

Pros And Cons Checklist

• SSRIs — effective antidepressant profile; may cause activation or insomnia in some patients.
• Mirtazapine — sedating and may increase appetite and weight.
• Doxepin — sedating tricyclic with anticholinergic effects; caution in elderly.
• Trazodone — sedating with low abuse potential; watch for orthostatic hypotension and rare priapism.

Shared Decision Aid:

• Discuss priorities such as sexual side effects, weight change, daytime sedation and interactions.
• Make a plan with your GP or mental health team and schedule review points.

Regulation Snapshot

MHRA Approval & NHS Prescribing Framework

Is trazodone regulated in the UK and how is it prescribed?

Trazodone is prescription‑only in all markets and is registered for major depressive disorder by regulators such as EMA and FDA in jurisdictions where it is approved.

GPs in the UK typically prescribe generic trazodone, and branded extended‑release products may be substituted depending on pharmacist advice and clinical need.

Prescription, Repeat Prescriptions, And Dispensing Tips

What should you check at the pharmacy?
