Medication

Does medication work for eating disorders?

We do not yet fully understand the brain biology of eating disorders, so research is limited at present. If you are considering medication, it is important to discuss the benefits and risks in general and specific to you with your doctor, and to take time to read the information leaflet before deciding.

Anorexia Nervosa

 At present, there is no research evidence that medication is an effective treatment for Anorexia Nervosa in terms of weight restoration or cognitions. It is not recommended as a treatment for Anorexia Nervosa (NICE, 2017).  There has been little research in children, and medication is not recommended. 

However, many people with Anorexia Nervosa also experience low mood and anxiety. This can be as a result of the impact of low nutritional intake on the brain and body.  When someone has a co-occuring clinical anxiety or depression, antidepressant or antianxiety medication may be of help . These types of medications may not be as effective in people who are very underweght because of lower levels of serotonin in the brain.

Bulimia Nervosa

There is some limited research in adults suggesting that  Fluoxetine, an  Selective Serotonin Reuptake Inhibitors (SSRI) may be helpful to reduce the symptoms of Bulimia Nervosa at higher doses.  Side effects may be higher however.  Research on other medications is more limited. Currently, no medication is licenced in Ireland as a treatment for Bulimia Nervosa.

Medication may also be helpful for you if you have a co-occurring diagnosis of depression or anxiety.

Binge Eating Disorder

No medicaton is licenced for the treatment of Binge Eating Disorder in Ireland. As with Bulimia Nervosa, where co-occuring depression or anxiety exists, there is very limited research in adults to suggest that an antidepressant or lisdexamphetamine may be considered (APA, 2022). The NICE guidelines 2017 do not recommend medication for the treatment of Binge Eating Disorder for adults or children.

ARFID

Research findings on medication is not available to date in relation to ARFID , so it is not recommended at this time. 

Children and Adolescents

There has been very little research in this age group to date. Medication is therefore not recommended to treat eating disorder symptoms and behaviours in people under 18 years.
