Binge eating disorder (BED) is the most common eating disorder in the United States, affecting approximately 2.8 million adults. While psychotherapy—particularly Cognitive Behavioral Therapy (CBT)—remains the gold standard for treatment, many individuals find that therapy alone is not sufficient to fully manage their symptoms. For these individuals, exploring medications for binge eating disorder can be a critical step toward lasting recovery.
When combined with comprehensive therapeutic support, medication can help reduce the frequency of episodes of binge eating, manage underlying mental health conditions, and improve overall quality of life. Understanding what medications are available, how they work, and their potential side effects is essential for anyone considering medical treatment for binge eating disorder in adults.
Why Medication May Be Needed for Binge Eating Disorder
Binge eating disorder is fundamentally a mental health condition with complex neurobiological underpinnings. Research has shown that individuals with BED often have dysregulation in the brain’s reward and impulse control systems, particularly involving dopamine pathways. This neurological component means that willpower alone is rarely sufficient to reduce binge eating episodes, and medication can play an important role in restoring balance.
Additionally, binge eating disorder in adults frequently co-occurs with other mental health conditions, including depression, anxiety, attention-deficit/hyperactivity disorder (ADHD), and post-traumatic stress disorder (PTSD). Medications that address these co-occurring conditions can simultaneously reduce the emotional triggers that drive binge eating behavior. The National Eating Disorders Association recognizes that integrated treatment—combining medication with psychotherapy—produces the best outcomes for patients with binge eating disorder.
FDA-Approved Medications for Binge Eating Disorder
Currently, there is only one medication specifically approved by the U.S. Food and Drug Administration (FDA) for the treatment of binge eating disorder in adults.
Vyvanse (Lisdexamfetamine Dimesylate)
In 2015, the FDA approved Vyvanse (lisdexamfetamine dimesylate) as the first and only medication to treat moderate to severe binge eating disorder in adults. Originally developed and approved for Attention-Deficit/Hyperactivity Disorder (ADHD), Vyvanse is a central nervous system stimulant that has demonstrated significant efficacy in reducing the number of binge eating days per week in clinical trials.
How it works: While the exact mechanism by which lisdexamfetamine dimesylate reduces binge eating episodes is not entirely understood, it is believed to alter the balance of neurotransmitters in the brain—particularly dopamine and norepinephrine. This helps decrease impulsivity and reduces the obsessive thoughts surrounding food that characterize binge-eating disorder, ultimately helping to reduce binge eating behavior in adults with binge-eating disorder.
Clinical evidence: In pivotal clinical trials, adults with binge-eating disorder who took Vyvanse experienced significantly fewer binge eating days per week compared to those taking a placebo. Many patients with binge eating disorder achieved complete cessation of binge eating episodes during the treatment period. These results established lisdexamfetamine dimesylate as an effective pharmacological option for the management of binge eating disorder.
Considerations: Because Vyvanse is a stimulant, it carries a risk of dependence and abuse. It is classified as a Schedule II controlled substance. It is not approved for weight loss, and its safety for long-term use in the management of binge eating disorder is still being studied. Common side effects include dry mouth, insomnia, increased heart rate, decreased appetite, and anxiety. It must be prescribed and carefully monitored by a qualified psychiatric professional experienced in eating disorder treatment.
Off-Label Medications Used for BED
While Vyvanse is the only FDA-approved medication specifically for BED, psychiatrists often prescribe other medications off-label to help manage the symptoms of binge eating disorder, especially when co-occurring mental health conditions are present. These medications have been studied in clinical trials and have shown meaningful benefits for patients with binge eating disorder.
Antidepressants (SSRIs and SNRIs)
Selective Serotonin Reuptake Inhibitors (SSRIs), such as fluoxetine (Prozac), sertraline (Zoloft), and escitalopram (Lexapro), are among the most commonly used off-label medications for binge eating disorder. Because binge eating disorder frequently co-occurs with depression and anxiety, SSRIs can be highly effective in treating these underlying conditions. By improving mood regulation and reducing anxiety, SSRIs can significantly decrease the emotional triggers that lead to episodes of binge eating.
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs), such as duloxetine (Cymbalta), have also shown promise in reducing binge eating frequency. These medications are particularly useful for patients who experience both depression and chronic pain, which can be a co-occurring condition in individuals with obesity related to their binge eating disorder.
Topiramate (Topamax)
Topiramate is an anticonvulsant medication originally approved to treat seizures and prevent migraines. In clinical studies, topiramate has been shown to significantly reduce binge eating episodes and promote weight loss in patients with binge eating disorder. It is believed to work by suppressing appetite, enhancing feelings of fullness, and reducing the reward value of food.
Research has demonstrated that topiramate can reduce the number of binge eating days per week by approximately 50% in some patients with binge eating disorder. However, it can have significant side effects, including cognitive dulling (often described as “brain fog”), tingling in the extremities, changes in taste, and kidney stones with long-term use. It is generally not recommended for women of childbearing age due to potential risks during pregnancy.
Naltrexone/Bupropion (Contrave)
Naltrexone/bupropion (brand name Contrave) is an FDA-approved weight loss medication that has also shown promise in reducing binge eating behavior. Bupropion is an antidepressant that also affects dopamine pathways, while naltrexone blocks opioid receptors involved in the reward system. Together, they can help reduce the compulsive drive to binge eat. This combination may be particularly beneficial for adults with binge-eating disorder who also struggle with obesity and co-occurring depression.
Comparing Medication Options for BED
| Medication Type | Examples | How It Helps BED | Key Considerations |
| FDA-Approved Stimulant | Vyvanse (lisdexamfetamine dimesylate) | Only FDA-approved option; reduces impulsivity and binge frequency in adults with binge-eating disorder. | Schedule II controlled substance; risk of dependence; not for weight loss. |
| Antidepressants (SSRIs) | Prozac, Zoloft, Lexapro | Treats co-occurring depression and anxiety that trigger episodes of binge eating. | Off-label for BED; may take 4–6 weeks to see full effects. |
| Anticonvulsants | Topiramate (Topamax) | Reduces binge eating episodes and can promote weight loss. | Off-label; risk of cognitive side effects; not recommended during pregnancy. |
| Combination Weight Loss | Naltrexone/Bupropion (Contrave) | Reduces reward-driven eating behavior and addresses co-occurring depression. | FDA-approved for obesity; off-label for BED specifically. |
What Medications Are Not Appropriate for BED
It is important to note that not all weight loss or appetite suppressant medications are appropriate for the management of binge eating disorder. Some medications, particularly those that work purely by suppressing appetite, do not address the psychological and neurobiological drivers of BED and may even worsen the disorder by increasing feelings of deprivation that trigger binge eating.
Additionally, medications that carry a high risk of abuse or dependence should be used with extreme caution in individuals with BED, as the disorder is associated with impulsive behavior and, in some cases, co-occurring substance use disorders. Any medication decision should be made in close collaboration with a qualified eating disorder psychiatrist who understands the treatment of binge eating disorder.
The Importance of Integrated Psychiatric Care
Medication is rarely a standalone treatment for binge eating disorder. The most effective treatment plans for binge eating disorder in adults integrate medication management with comprehensive psychotherapy and nutritional counseling. Medication can help stabilize brain chemistry and reduce the intense urges associated with binge-eating disorder, creating the mental space necessary for individuals to engage fully in therapy.
In therapy, individuals learn to identify emotional triggers, develop healthy coping mechanisms, and address the root causes of their eating disorder. Cognitive Behavioral Therapy (CBT) helps patients recognize and change the distorted thought patterns that drive binge eating behavior. Dialectical Behavior Therapy (DBT) is particularly effective for individuals whose binge eating is driven by emotional dysregulation. A registered dietitian can also provide essential guidance on establishing regular, balanced eating patterns that support long-term recovery from binge eating disorder.

Frequently Asked Questions
What is the only FDA-approved medication for binge eating disorder?
Vyvanse (lisdexamfetamine dimesylate) is currently the only medication specifically approved by the FDA to treat moderate to severe binge eating disorder in adults. It was approved in 2015 and has been shown to significantly reduce episodes of binge eating in clinical trials of adults with binge-eating disorder.
Can antidepressants help with binge eating disorder?
Yes. Antidepressants, particularly SSRIs such as fluoxetine and sertraline, are often prescribed off-label for binge-eating disorder. They are especially helpful for individuals whose binge eating is triggered by co-occurring depression or anxiety, which are common in patients with binge eating disorder.
Is medication enough to treat binge eating disorder?
No. Medication is most effective when used as part of a comprehensive treatment plan that includes psychotherapy (such as CBT or DBT) and nutritional counseling. Medication alone does not address the behavioral and emotional roots of binge eating disorder and is best used as a complement to therapy for binge eating disorder in adults.
Are there medications for binge eating disorder that also help with weight loss?
Some off-label medications used for BED, such as topiramate and naltrexone/bupropion, may result in weight loss for some individuals. However, Vyvanse is not approved for weight loss. The primary goal of medications for binge eating disorder is to reduce the frequency of binge eating episodes and manage underlying mental health conditions.
