1. WHAT TRAZODONE IS AND WHAT IT IS USED FOR
The name of your medicine is Trazodone Hydrochloride 50mg or 100mg Capsules (called trazodone in this leaflet). This belongs to a group of medicines called antidepressants.
Trazodone can be used to treat anxiety and depression.
2. BEFORE YOU TAKE TRAZODONE
Do not take this medicine and tell your doctor if you:
- are allergic to trazodone or any of the other ingredients of these capsules (listed in section 6).
Signs of an allergic reaction can include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.

Do not take this medicine if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking trazodone.
Take special care with trazodone
Thoughts of suicide and worsening of your depression or anxiety disorder
If you are depressed and/or have anxiety disorders you can sometimes have thoughts of harming or killing yourself. These may be increased when first starting antidepressants, since these medicines all take time to work, usually about two weeks but sometimes longer.
You may be more likely to think like this if you:
- have previously had thoughts about killing or harming yourself.
- are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant.
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.
You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behaviour.
Trazodone should not be used in children and adolescents under 18 years of age.
If you are elderly, you may be more prone to side effects, increased caution is necessary especially when taking other medicines at the same time as trazodone or if you have some other diseases.
Check with your doctor or pharmacist before taking this medicine if you:
- have or have ever had fits or seizures (epilepsy)
- have severe liver, kidney or heart problems
- are pregnant, trying to become pregnant or are breast-feeding
- have an overactive thyroid gland (hyperthyroidism)
- have problems passing water or need to pass water (urine) frequently
- have narrow angle glaucoma (an eye disorder)
- have schizophrenia or other type of mental disorder
- are elderly, as you may be more prone to side effects
- are taking buprenorphine (a strong pain killer). The use of buprenorphine with trazodone can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and trazodone”).
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking trazodone.
Other medicines and trazodone
