Binge Eating Disorder (BED) is a serious mental health condition characterized by recurrent episodes of consuming unusually large amounts of food in a short period of time, accompanied by a sense of loss of control. Unlike bulimia nervosa, BED does not involve compensatory behaviors like purging or excessive exercise. This can lead to significant distress, health problems, and a diminished quality of life. While therapy and lifestyle changes are often the first line of treatment, medication can play a crucial role in managing BED, especially when combined with other approaches. This article explores the different medications that are used or being investigated for the treatment of binge eating disorder, their mechanisms of action, potential benefits, and possible side effects.
FDA-Approved Medication for Binge Eating Disorder
The Food and Drug Administration (FDA) has approved only one medication specifically for the treatment of moderate to severe binge eating disorder: lisdexamfetamine dimesylate (Vyvanse).
Lisdexamfetamine Dimesylate (Vyvanse)
Lisdexamfetamine dimesylate is a central nervous system stimulant primarily used for the treatment of Attention Deficit Hyperactivity Disorder (ADHD). However, its effectiveness in reducing binge eating episodes led to its FDA approval for BED in 2015.
How it Works: Lisdexamfetamine is a prodrug, meaning it is inactive until it is metabolized by the body into dextroamphetamine, a stimulant that affects neurotransmitters in the brain, primarily dopamine and norepinephrine. These neurotransmitters play a role in reward, motivation, and impulse control. By increasing the levels of these neurotransmitters, lisdexamfetamine can help reduce impulsivity, improve focus, and decrease the urge to binge eat.
Benefits of Vyvanse for BED: Clinical trials have demonstrated that lisdexamfetamine can significantly reduce the frequency of binge eating episodes and the number of days per week with binge eating. Patients taking lisdexamfetamine also reported a decrease in their preoccupation with food and improved control over their eating habits. Additionally, some individuals experienced weight loss as a secondary benefit.
Side Effects: Like all medications, lisdexamfetamine can cause side effects. Common side effects include:
- Decreased appetite
- Insomnia
- Dry mouth
- Anxiety
- Irritability
- Increased heart rate
- Increased blood pressure
More serious, though less common, side effects include cardiovascular problems, psychiatric symptoms, and potential for misuse and dependence. Individuals with a history of heart problems, mental health disorders, or substance abuse should use lisdexamfetamine with caution and under close medical supervision. It is essential to discuss all potential risks and benefits with a healthcare provider before starting lisdexamfetamine.
Dosage and Administration: Lisdexamfetamine is typically taken once daily in the morning. The starting dose is usually low and gradually increased by the healthcare provider to minimize side effects and achieve the desired therapeutic effect. It is crucial to follow the prescribed dosage and not to abruptly stop taking the medication, as this can lead to withdrawal symptoms.
Off-Label Medications for Binge Eating Disorder
While lisdexamfetamine is the only FDA-approved medication specifically for BED, other medications are sometimes used “off-label” to manage the disorder. Off-label use means that the medication is being used for a purpose other than what it was originally approved for. A doctor can prescribe medication off-label if they believe it is medically appropriate for the patient’s condition.
Antidepressants
Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), are often prescribed for BED due to the high comorbidity between BED and mood disorders like depression and anxiety.
SSRIs: SSRIs work by increasing the levels of serotonin in the brain, a neurotransmitter that plays a role in mood regulation, appetite control, and impulse control.
Examples of SSRIs used for BED:
- Fluoxetine (Prozac): Fluoxetine was one of the first SSRIs used to treat bulimia nervosa, and it has also shown some effectiveness in reducing binge eating episodes in individuals with BED, though it is not FDA-approved for this specific purpose.
- Sertraline (Zoloft): Sertraline can help manage the underlying anxiety and depression that may contribute to binge eating.
- Citalopram (Celexa): Citalopram is another SSRI that may be used to address mood-related symptoms associated with BED.
Side Effects of SSRIs: Common side effects of SSRIs include nausea, diarrhea, insomnia, decreased libido, and weight gain. These side effects can vary from person to person.
Other Antidepressants:
- Venlafaxine (Effexor): A serotonin-norepinephrine reuptake inhibitor (SNRI) that may be helpful if SSRIs are not effective or tolerated. It affects both serotonin and norepinephrine levels.
- Bupropion (Wellbutrin): A norepinephrine-dopamine reuptake inhibitor (NDRI) that can be helpful for individuals with BED who also experience low energy or fatigue.
Important Note: It’s essential to be aware of the potential for increased suicidal thoughts or behaviors, especially in young adults, when starting antidepressant medication. Close monitoring by a healthcare professional is crucial.
Anticonvulsants
Certain anticonvulsant medications have shown promise in reducing binge eating episodes, particularly those that affect the neurotransmitter gamma-aminobutyric acid (GABA).
Topiramate (Topamax): Topiramate is an anticonvulsant that is sometimes used off-label for BED.
How it Works: The exact mechanism of action of topiramate in BED is not fully understood, but it is believed to affect several neurotransmitter systems in the brain, including GABA, glutamate, and dopamine. It may help reduce cravings, suppress appetite, and improve impulse control.
Benefits of Topiramate for BED: Studies have shown that topiramate can reduce the frequency of binge eating episodes and promote weight loss in individuals with BED.
Side Effects: Common side effects of topiramate include:
- Cognitive problems (difficulty with memory and concentration)
- Tingling in the hands and feet
- Nausea
- Weight loss
- Dizziness
More serious, though less common, side effects include kidney stones and glaucoma.
Other Medications
Several other medications are being investigated or used off-label for the treatment of BED, although the evidence supporting their effectiveness is limited.
- Orlistat (Alli, Xenical): A lipase inhibitor that blocks the absorption of fat in the intestines. While it can promote weight loss, it does not directly address the underlying psychological issues that contribute to BED. It is used for weight management, which can indirectly help with the consequences of BED.
- Naltrexone/Bupropion (Contrave): This combination medication is approved for weight management and contains naltrexone, an opioid antagonist, and bupropion, an antidepressant. It may help reduce cravings and improve impulse control, but more research is needed to determine its effectiveness in BED.
Important Considerations Before Starting Medication
Before starting any medication for binge eating disorder, it’s crucial to have a thorough evaluation by a healthcare professional, including a psychiatrist or a physician specializing in eating disorders. Several factors need to be considered:
- Diagnosis: A proper diagnosis of BED is essential to ensure that medication is appropriate.
- Medical History: The healthcare provider needs to be aware of the individual’s medical history, including any pre-existing medical conditions, allergies, and current medications.
- Mental Health History: A history of mental health disorders, such as depression, anxiety, bipolar disorder, or substance abuse, should be discussed with the healthcare provider, as it may influence the choice of medication.
- Potential Drug Interactions: Certain medications can interact with other medications, so it’s important to inform the healthcare provider about all medications being taken, including over-the-counter drugs and supplements.
- Pregnancy and Breastfeeding: Some medications are not safe to take during pregnancy or breastfeeding, so it’s essential to inform the healthcare provider if the individual is pregnant, planning to become pregnant, or breastfeeding.
The Role of Therapy and Lifestyle Changes
Medication is often most effective when combined with therapy and lifestyle changes. Therapy can help individuals address the underlying psychological issues that contribute to binge eating, such as low self-esteem, body image concerns, and emotional dysregulation.
Cognitive Behavioral Therapy (CBT): CBT is a type of therapy that helps individuals identify and change negative thought patterns and behaviors that contribute to binge eating. It teaches coping skills to manage triggers and cravings.
Dialectical Behavior Therapy (DBT): DBT is a type of therapy that helps individuals regulate their emotions, improve their interpersonal skills, and tolerate distress. It can be particularly helpful for individuals with BED who also struggle with emotional dysregulation.
Interpersonal Therapy (IPT): IPT focuses on improving interpersonal relationships and addressing any social or relationship issues that may be contributing to binge eating.
Lifestyle Changes: In addition to therapy, lifestyle changes can also play a crucial role in managing BED. These include:
- Regular Exercise: Exercise can help improve mood, reduce stress, and promote weight loss.
- Healthy Eating Habits: Developing healthy eating habits, such as eating regular meals and snacks, avoiding restrictive diets, and practicing mindful eating, can help reduce the urge to binge eat.
- Stress Management Techniques: Learning stress management techniques, such as yoga, meditation, or deep breathing exercises, can help reduce stress and prevent emotional eating.
- Support Groups: Joining a support group can provide individuals with a sense of community and support, as well as an opportunity to share their experiences and learn from others.
Future Directions in Medication Development
Research is ongoing to develop new and more effective medications for the treatment of binge eating disorder. Some promising areas of research include:
- Glucagon-Like Peptide-1 (GLP-1) Receptor Agonists: These medications are primarily used for the treatment of type 2 diabetes, but they have also been shown to promote weight loss and reduce appetite. Some studies have suggested that they may be effective in reducing binge eating episodes.
- Combination Therapies: Combining different medications that target different aspects of BED may be more effective than using a single medication. For example, combining an antidepressant with an appetite suppressant may be a promising approach.
- Targeting Specific Brain Circuits: Researchers are working to identify the specific brain circuits that are involved in binge eating and develop medications that target these circuits.
Conclusion
Binge eating disorder is a complex condition that often requires a multifaceted approach to treatment. While lisdexamfetamine is the only FDA-approved medication specifically for BED, other medications, such as antidepressants and anticonvulsants, may be used off-label to manage the disorder. Medication is often most effective when combined with therapy and lifestyle changes. It’s crucial to have a thorough evaluation by a healthcare professional before starting any medication for BED and to discuss all potential risks and benefits. Ongoing research is focused on developing new and more effective medications for this challenging condition, offering hope for improved treatment outcomes in the future. Remember to always consult with your doctor or a qualified healthcare professional for any medical advice or treatment.

What is the first-line medication treatment for Binge Eating Disorder?
Lisdexamfetamine dimesylate, marketed under the brand name Vyvanse, is the first FDA-approved medication specifically for the treatment of moderate to severe Binge Eating Disorder (BED) in adults. It works by affecting neurotransmitters in the brain, particularly dopamine and norepinephrine, which are thought to play a role in controlling impulsive behaviors and regulating appetite. Clinicians typically start with a low dose and gradually increase it based on individual response and tolerability, monitoring for potential side effects.
While Vyvanse can be effective in reducing the frequency of binge eating episodes and improving associated psychological distress, it is important to remember that medication alone is not a complete solution. Comprehensive treatment often involves psychotherapy, such as cognitive behavioral therapy (CBT), and nutritional counseling to address underlying emotional and behavioral patterns that contribute to the disorder. The goal is to create a holistic approach that supports long-term recovery and sustainable changes in eating habits.
How does Lisdexamfetamine dimesylate (Vyvanse) work to treat Binge Eating Disorder?
Lisdexamfetamine dimesylate is a central nervous system stimulant that works by increasing the levels of dopamine and norepinephrine in the brain. These neurotransmitters are involved in regulating attention, focus, and impulse control. By increasing their availability, Vyvanse helps reduce the urge to binge eat and improves the individual’s ability to control their eating behavior. The medication is a prodrug, meaning it is converted into its active form (dextroamphetamine) in the body, resulting in a longer-lasting effect.
The specific mechanisms by which Vyvanse reduces binge eating are not fully understood, but it is believed that the medication’s effect on dopamine pathways reduces the reward associated with binge eating and increases satiety. This can lead to a decreased frequency of binge eating episodes and improved overall eating habits. However, it is crucial to understand that Vyvanse is not a weight-loss drug and should not be used for that purpose. Its effectiveness is primarily in reducing the core symptom of BED: the recurrent episodes of consuming large amounts of food in a short period with a sense of loss of control.
What are the potential side effects of Vyvanse?
Common side effects of Vyvanse can include dry mouth, decreased appetite, insomnia, anxiety, increased heart rate, and increased blood pressure. Some individuals may also experience weight loss, nausea, or abdominal pain. It is crucial to discuss any pre-existing medical conditions, especially heart problems or psychiatric disorders, with a doctor before starting Vyvanse, as it may not be suitable for everyone.
More serious, though less common, side effects can include cardiovascular complications such as sudden death in individuals with pre-existing heart conditions, as well as psychiatric side effects such as psychosis or mania. Vyvanse is also a controlled substance, and there is a risk of misuse and dependence. Therefore, close monitoring by a healthcare professional is essential throughout treatment. It is also important to note that side effect profiles can vary from person to person.
Are there alternative medications for Binge Eating Disorder besides Vyvanse?
While Vyvanse is the only FDA-approved medication specifically for BED, some other medications may be used off-label to manage associated symptoms or comorbid conditions. Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) like fluoxetine, sertraline, and paroxetine, are sometimes prescribed to address underlying depression or anxiety, which can contribute to binge eating. These medications can help improve mood and reduce impulsive behaviors in some individuals.
Topiramate, an anticonvulsant medication, has also been used off-label for BED due to its appetite-suppressing effects. However, it’s important to note that the effectiveness of these medications for treating BED can vary, and they are not considered first-line treatments. The decision to use alternative medications should be made in consultation with a healthcare professional who can assess the individual’s specific needs and weigh the potential benefits and risks. Furthermore, therapy and lifestyle modifications are usually recommended alongside any medication.
Can antidepressants help with Binge Eating Disorder?
Antidepressants, particularly SSRIs, can sometimes be helpful in treating BED, especially when it co-occurs with depression or anxiety. These medications work by increasing the levels of serotonin in the brain, which can improve mood and reduce impulsive behaviors. While SSRIs may not directly target the binge eating behavior, they can help address underlying emotional issues that contribute to the disorder.
It’s important to note that antidepressants may not be effective for everyone with BED, and they are not a substitute for other forms of treatment, such as psychotherapy and nutritional counseling. Also, it’s crucial to discuss the potential side effects of antidepressants with a healthcare professional before starting treatment. The effectiveness of antidepressants for BED can vary from person to person, and careful monitoring is necessary to determine if they are providing benefit.
Is medication the only treatment option for Binge Eating Disorder?
Medication is not the only treatment option for BED, and a comprehensive treatment approach often involves a combination of medication, psychotherapy, and nutritional counseling. Psychotherapy, particularly cognitive behavioral therapy (CBT), is a highly effective treatment for BED. CBT helps individuals identify and change negative thoughts and behaviors that contribute to binge eating episodes. It also teaches coping skills for managing emotions and stressful situations without resorting to food.
Nutritional counseling plays a crucial role in helping individuals develop healthy eating habits and improve their relationship with food. A registered dietitian can provide guidance on meal planning, portion control, and mindful eating techniques. The combination of medication, therapy, and nutritional counseling offers the best chance for long-term recovery from BED by addressing both the psychological and physical aspects of the disorder. The specific approach will vary depending on individual needs and preferences.
How long will I need to take medication for Binge Eating Disorder?
The duration of medication treatment for BED varies depending on individual needs and response to treatment. Some individuals may need to take medication for several months to years to maintain symptom control, while others may be able to gradually taper off medication under the guidance of a healthcare professional. The decision to discontinue medication should be made in consultation with a doctor, who can assess the individual’s progress and determine if they are able to maintain their recovery without medication.
It is important to remember that medication is often most effective when combined with other forms of treatment, such as psychotherapy and nutritional counseling. As individuals develop coping skills and healthy eating habits through these therapies, they may be able to reduce their reliance on medication. Regular follow-up appointments with a healthcare professional are essential to monitor progress, adjust medication dosages as needed, and address any potential side effects. Ultimately, the goal is to achieve long-term recovery and maintain a healthy relationship with food.
