Trazodone belongs to a group of medicines that act on serotonin in the brain. It is taken by mouth, usually as part of a plan agreed with a prescriber, and it is not a quick fix: antidepressants often need time to work. This page explains what the tablets are, how the UK leaflet says they are used, the main warnings, and how ordering works for the UK, Australia, the USA, the UAE, Russia and other countries.
The dm+d, the NHS dictionary of medicines, lists trazodone 100 mg tablets in packs of 56 tablets (4 x 14). Read the leaflet in your pack before your first dose, and keep it for reference.

How it works
Trazodone changes the way serotonin signals work in the brain. Serotonin is a chemical messenger linked to mood, anxiety and sleep. By adjusting its activity, trazodone helps lift low mood and ease anxiety over time. It also has a calming effect, which is why drowsiness is one of the most common effects.
Uses
Depression: the UK product information for trazodone lists treatment of depression, with or without anxiety, as the main use.
Anxiety: the same UK information also lists anxiety as an approved use, with a different dose range from depression.
Who it is not for: the UK product information says there are not enough safety data to recommend trazodone in anyone under 18 years of age.
Trazodone is sometimes prescribed for other reasons, such as sleep. Such uses are decisions for the prescriber, and this page only describes the uses given in the UK product information. Never start, stop or change an antidepressant without speaking to your prescriber.
Dosage and how to take it
The UK product information for trazodone describes doses that are set by the prescriber. For depression, it describes a starting dose of around 150 mg a day, given in divided doses or as a single night-time dose, which can be raised to a maximum of 300 mg a day if needed. For anxiety, it describes 75 mg a day, which can be increased to 300 mg a day. For very elderly or frail people, the recommended starting dose is lower, at 100 mg a day.
The leaflet advises taking tablets after food, because this can reduce some side effects. Swallow them with water. Do not stop suddenly, as this can cause withdrawal symptoms. Always follow the leaflet in the pack and your prescriber's or pharmacist's instructions. The UK information also says prescribers should limit the quantity supplied at each occasion, particularly when treatment starts.
Storage Instructions
Keep the tablets in the original pack, away from moisture and out of the sight and reach of children. Store them as the label on your pack says, and do not use them after the expiry date printed on it. Ask a pharmacist how to dispose of unused tablets safely.
Possible side effects
- Drowsiness and sedation
- Dizziness or light-headedness
- Headache
- Dry mouth
- Nausea or an upset stomach
- Blurred vision
- Constipation
- Tiredness or confusion
- Low blood pressure when standing up
Serious reactions are less common. They include thoughts of harming yourself, a painful erection that lasts for hours (priapism), an irregular heartbeat, fits and signs of serotonin syndrome such as agitation, sweating, fever and muscle twitching. Seek urgent medical help if any of these happen. You can also report suspected side effects to the MHRA Yellow Card scheme.
Safety
Talk to a doctor first if you are pregnant, breastfeeding, taking other medicines, or have a medical condition.
- Thoughts of suicide: antidepressants can increase suicidal thoughts and behaviour, especially at the start of treatment or after a dose change. The USA label carries a boxed warning for this. Contact a doctor or emergency services at once if you have such thoughts.
- Priapism: a prolonged painful erection is a medical emergency. Stop the tablets and seek help immediately.
- Serotonin syndrome: take extra care with other serotonin-raising medicines, such as other antidepressants, triptans and St John's wort.
- MAO inhibitors: do not take trazodone with, or within two weeks of stopping, a monoamine oxidase inhibitor, unless your prescriber directs it.
- Heart rhythm: tell your prescriber about heart disease, or medicines that affect heart rhythm, before you start.
- Alcohol: alcohol can increase drowsiness and is best avoided.
- Driving: do not drive or use machinery if you feel drowsy or dizzy.
- Pregnancy and breastfeeding: talk to your prescriber before using trazodone if you are pregnant, planning a pregnancy or breastfeeding.
- Children and teenagers: not recommended under 18 years, according to the UK product information.
- Overdose: an overdose is dangerous. Seek emergency medical help straight away.
