Purpose and aims
Trazodone is an antidepressant available only on prescription in the UK. It is usually prescribed for major depressive disorder but is also commonly used off-label to improve sleep or to help with anxiety symptoms. In some pain services it forms part of a multi-modal approach when a sedating antidepressant is wanted.
Only take trazodone when a qualified clinician has prescribed it for you. Follow the directions on the label and read the patient information leaflet that comes with the pack. For quick links to practical points see dose administration process, critical steps after missing a dose and protective measures for safety.

How does trazodone work in treatment
Trazodone acts on serotonin systems by blocking particular serotonin receptors and by modestly inhibiting serotonin reuptake. It also interacts with histamine and alpha-1 adrenergic receptors, which explains common sedative effects plus the potential for dizziness on standing.
The combination of serotonergic and receptor-blocking actions produces both antidepressant and sleep-promoting effects in many patients.
Dose delivery and administration
Always follow the dose and schedule your prescriber sets. If something in the patient leaflet is unclear, ask your pharmacist or prescriber for clarification.
- Take trazodone with a light meal or shortly after eating to reduce stomach upset.
- Swallow modified-release tablets whole; do not crush or chew them. Consult with your advisor a pharmacist before changing tablet form.
- Many people take the larger dose in the evening because trazodone can cause drowsiness. Clinicians may split the daily dose for some patients.
- Avoid bringing the motion to a halt suddenly. When treatment ends, a prescriber will usually recommend a gradual reduction to avoid withdrawal symptoms.
- Avoid alcohol while using trazodone because alcohol increases sedation and impairs coordination.
- Older adults and those with reduced liver or kidney function typically start at lower doses, with cautious upward titration if needs be.
If you need advice about timing or dose adjustments see your prescriber or local pharmacist and refer to instructions for a dose that was missed if you skip a dose.
If you have missed a dose
When you miss a tablet, take it as soon as you remember unless the next dose will be due soon. If the next dose is imminent, skip the forgot to take the dose and carry on with the usual schedule. Do not take two doses at once to offset a forgot to take the dose.
Secure handling, inventory storage keeps products ready for sale. and removal
- Store at controlled room temperature, typically between 20 and 25 degrees C. Short excursions between 15 and 30 degrees C are usually acceptable.
- Keep trazodone in its original container, tightly closed and protected from moisture and direct sunlight. It is not allowed to be stored in the bathroom.
- Keep medicines out of the reach and sight of children and animals.
- Do not flush unused tablets. Return expired or unwanted medicines to a pharmacy for safe disposal.
Preventive steps and warning notices
When trazodone should not be used
- Known hypersensitivity to trazodone, nefazodone or any excipient in the product.
- Concurrent use of sodium oxybate is contraindicated.
Tell your clinician if any of the following apply
- You are pregnant, trying to conceive or breastfeeding. See during pregnancy and lactation to get more details.
- You have heart disease, irregular heart rhythm, a recent myocardial infarction or low blood pressure.
- You have epilepsy or a past history of seizures, bipolar disorder or suicidal thoughts.
- You suffer from glaucoma, urinary retention or an enlarged prostate.
- Your liver or kidney function is significantly reduced.
- You drink alcohol regularly or take other medicines that cause drowsiness.
- You are due to have an operation that requires sedation.
Important risks to watch for
- Serotonin syndrome: may occur when trazodone is combined with other serotonergic medicines. Symptoms include agitation, high temperature, sweating, rapid heartbeat, muscle stiffness and confusion. Seek urgent care if suspected.
- Priapism: a prolonged painful erection lasting longer than four hours is a medical emergency.
- Orthostatic hypotension: feel faint or dizzy when standing. Rise slowly from sitting or lying positions.
- Increased bleeding risk with anticoagulants or antiplatelet medicines; report unexpected bruising or bleeding.
- New or increasing suicidal thoughts or changes in mood, especially when starting or changing dose. Contact your prescriber urgently if this occurs.
- Impaired alertness: do not drive or operate dangerous machinery if you feel drowsy or dizzy.
Pregnancy and breast feeding
Decisions about initiating or continuing trazodone in pregnancy or during lactation should be personalised. Small amounts of trazodone pass into breast milk and neonatal withdrawal or sedation has been reported after maternal use in pregnancy. Discuss risks and benefits with your prescriber if you are pregnant, planning pregnancy or breastfeeding.
For more safety points to review see warning announcements and risk mitigation steps and consult specialist advice where relevant.
The influence of food on drug action
Always provide a full list of prescription medicines, over the counter products, herbal remedies and supplements to your clinician or pharmacist. Influential exchanges include:
- Other serotonergic drugs raise the risk of serotonin syndrome: SSRIs, SNRIs, MAO inhibitors, triptans, lithium, linezolid and St Johns wort flower. Avoid combination with MAO inhibitors and allow an appropriate washout period.
- CNS depressants such as alcohol, benzodiazepines, opioids and sodium oxybate increase sedation and respiratory depression risk.
- CYP3A4 inhibitors can raise trazodone blood levels: for example ketoconazole, itraconazole, clarithromycin and some protease inhibitors, and grapefruit juice.
- CYP3A4 inducers such as carbamazepine and phenytoin may reduce trazodone exposure.
- Drugs like digoxin or phenytoin may need supervision and monitoring when co-prescribed with trazodone because blood levels can be affected.
- Phenothiazines can increase cardiac conduction and sedative unfavorable effects when combined with trazodone.
- Anticoagulants and antiplatelet agents plus some herbal products may raise bleeding risk; monitor for unusual bleeding.
If tracking the back and forth of communications helps measure engagement. are possible your prescriber may choose natural health medicines, modify doses or arrange additional monitoring in real time.
Possible negative effects
Many adverse health effects are most noticeable early in treatment and diminish over time. Contact your clinician if chronic side effects are persistent or troublesome.
- Common: drowsiness, tiredness, dizziness or light-headedness.
- Gastrointestinal: dry mouth, nausea, constipation or abdominal discomfort.
- Neurological: pressure in my head, tremor, nervousness or coordination issues.
- Other: blurred vision, nasal congestion, fluid retention and muscle pains.
- Variations in appetite or sleep pattern are also reported.
Seek immediate medical help for serious signs such as severe allergic reaction with facial swelling or breathing difficulty, fainting, severe chest pain, prolonged erection, seizures, or symptoms of serotonin syndrome (high temperature, sweating, stiff muscles, confusion).
In an emergency call 999. For urgent but non-life-threatening NHS advice call 111.
Alternative drugs and similar pharmaceutical options
Choice of an a different possibility depends on the diagnosis, comorbid conditions and concomitant medicines. Commonly accepted substitutes include:
- SSRIs: sertraline, citalopram and escitalopram are often first-line for depression and many anxiety disorders and are generally less sedating than trazodone.
- SNRIs: venlafaxine and duloxetine can be preferred when depression coexists with chronic pain.
- Mirtazapine medication: more sedating and can boost appetite; used when sleep or weight gain is desired.
- Tricyclic antidepressants: amitriptyline or nortriptyline can help sleep and neuropathic pain but have more anticholinergic effects.
- Vortioxetine tablet formulation: an the alternative choice with a different tolerability profile and possibilities cognitive benefits in some patients.
- Short-term hypnotics: zopiclone or zolpidem for severe insomnia; note benzodiazepines and some hypnotics carry dependence risks and are controlled.
Trazodone is often selected when an antidepressant with calming or sleep-promoting effects is preferred. For a quick cost comparison in the UK see estimated Price levels in the UK.
