Warnings and precautions

Take special care with Trazodone Oral Solution

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.

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 Oral Solution or if you have some other diseases.

Talk to your doctor or pharmacist before taking Trazodone Oral Solution if you:
  • have or have ever had fits or seizures
  • 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 together with Trazodone Oral Solution can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Trazadone Oral Solution”).

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking Trazodone Oral Solution.

Children and adolescents

Trazodone Oral Solution should not be used in children and adolescents under 18 years of age.

Other medicines and Trazodone Oral Solution

Contact your doctor when experiencing such symptoms
  • sedatives (such as tranquilizers or sleeping pills)
  • medicines used to treat epilepsy such as carbamazepine and phenytoin
  • medicines used to treat high blood pressure, for example, clonidine
