Who can and cannot take trazodone

Who can take trazodone

Most adults aged 18 years and over can take trazodone.

If you have diabetes, trazodone can make it more difficult to keep your blood sugar stable. Your doctor may advise that you monitor your blood sugar more often for the first few weeks of treatment with trazodone, and adjust your diabetes treatment if necessary.

Speak to your doctor if your blood sugar levels are causing you concern.

Who may not be able to take trazodone

Trazodone is not suitable for some people. To make sure it's safe for you, check with your doctor before starting to take it if you:

  • have ever had an allergic reaction to trazodone or any other medicine
  • have ever had thoughts of self-harming or ending your life
  • have recently had a heart attack or have heart, kidney or liver problems
  • have epilepsy or are having electroconvulsive treatment – trazodone may increase your risk of having a seizure
  • are pregnant, trying to get pregnant or breastfeeding
  • have porphyria, a rare disorder
  • have phaeochromocytoma, a condition that affects the adrenal glands
