Lisdexamfetamine for Binge Eating Disorder: A Double-Edged Sword
Binge eating disorder (BED), the most common eating disorder in the United States, affects millions across diverse racial and ethnic groups. Yet, despite its prevalence, there remains a glaring lack of medications specifically designed to treat it. Enter lisdexamfetamine, the only FDA-approved drug for moderate to severe BED in adults. While it has shown promise in reducing binge episodes, a recent study by Rutgers Health researchers reveals that its benefits come with significant challenges.

Lisdexamfetamine,marketed as Vyvanse,was initially approved for ADHD. Its ability to curb binge eating episodes led to its FDA approval for BED in 2015.According to Morgan James, assistant professor of psychiatry and senior author of the study, “Its ability to also reduce the frequency of binge eating episodes led to its approval for binge eating disorder.”
However, the drug’s efficacy is not without complications. Patients reported that its effects often wear off by evening, increasing the risk of nighttime binge episodes. Additionally, side effects such as fatigue, irritability, and insomnia have left many struggling to balance the drug’s benefits with its drawbacks.
Self-Adjustment and Mixed Results
Some patients attempted to self-adjust thier dosage timing, taking the medication closer to their typical binge hours. While this approach sometimes helped manage symptoms, it often resulted in sleep disturbances and afternoon energy crashes. “The need for targeted treatment options for binge eating disorder remains a significant, unmet challenge in mental health care,” said Abanoub Armanious, lead author of the study and a master’s student at the Rutgers School of Public Health.
The Call for Better Solutions
The study underscores the urgent need for new medications tailored specifically for BED. Current treatments like lisdexamfetamine,while effective in reducing binge episodes,often fail to align with patients’ eating patterns and come with a host of side effects.
Key Findings at a Glance
| Aspect | Details |
|———————————|—————————————————————————–|
| Efficacy | Reduces binge eating episodes, but effects often wear off by evening. |
| Side Effects | Fatigue, irritability, insomnia, and afternoon energy crashes. |
| Patient Adjustments | Some self-adjust dosage timing, leading to mixed results. |
| Need for Advancement | New medications with fewer side effects and better alignment with BED. |
Moving Forward
The findings highlight the dual-sided experiences of patients using lisdexamfetamine, shedding light on both its perceived benefits and challenges. As researchers continue to explore more nuanced treatment options, the hope is to develop medications that not only reduce binge episodes but also improve overall quality of life for those living with BED.For now, the journey toward effective BED treatment remains a work in progress, with lisdexamfetamine serving as both a stepping stone and a reminder of the complexities involved in mental health care.
Lisdexamfetamine for Binge Eating Disorder: A Promising Yet Imperfect Solution
Binge eating disorder (BED), a condition characterized by recurrent episodes of excessive food consumption, affects millions globally. Despite its prevalence,there remains a glaring gap in the treatment landscape: no drug has been specifically developed and FDA-approved for BED. This unmet need has led to the repurposing of medications like lisdexamfetamine, originally designed for ADHD, as a potential treatment. A recent study published in Psychiatry Research Communications delves into the subjective experiences of patients using lisdexamfetamine for BED, revealing both its promise and its limitations.
the Repurposing of Lisdexamfetamine
Lisdexamfetamine, sold under the brand name vyvanse, was initially approved for ADHD but later gained FDA approval for BED in 2015. Its mechanism of action, which involves increasing dopamine and norepinephrine levels in the brain, helps regulate appetite and impulse control. However, its transition from an ADHD medication to a BED treatment underscores a critical gap in mental health care.
“The repositioning of this drug from an ADHD medication to a treatment for binge eating disorder highlights a critical gap in the treatment landscape, as no drug has been specifically developed and FDA-approved for binge eating disorder, despite the disorder’s widespread prevalence both in the U.S. and globally,” said Armanious, lead author of the study. “the need for targeted treatment options for binge eating disorder remains a significant, unmet challenge in mental health care.”
Patient Experiences: A Mixed bag
To better understand how patients perceive lisdexamfetamine, researchers conducted a thematic analysis of 111 anonymous reviews on Drugs.com, an independent drug information platform. The study examined the relationship between patients’ subjective experiences and their ratings of the drug’s efficacy.
“our findings revealed that higher perceived efficacy was associated with improved focus and fewer side effects, while lower ratings were linked to concerns about diminishing therapeutic effects, insomnia, and afternoon energy loss,” Armanious explained.
Key Challenges with Lisdexamfetamine
While many patients reported reduced binge episodes and improved appetite control, others faced significant challenges:
- nighttime Binge Risk: Lisdexamfetamine’s appetite-suppressing effects typically wear off by evening, leaving patients vulnerable to nighttime binge episodes.
- The “Crash”: As the drug wears off, patients often experience fatigue, irritability, and mental fogginess.
- Self-Adjusted Dosage: Some patients altered their dosage timing to align with their binging hours, but this often led to insomnia and sleep disturbances.
These findings highlight the need for a more nuanced understanding of lisdexamfetamine’s effects on BED patients.
The Path forward
The study’s insights underscore the importance of developing new medications with improved side affect profiles. This is a major focus of ongoing research at the James Laboratory, which aims to address the unmet needs of BED patients.
| Key Findings on Lisdexamfetamine for BED |
|———————————————-|
| Positive effects | Reduced binge episodes, improved appetite control, enhanced focus |
| Negative Effects | Nighttime binge risk, fatigue, irritability, insomnia, mental fogginess |
| Patient Adjustments | Self-adjusted dosage timing often led to sleep disturbances |
Conclusion
Lisdexamfetamine represents a significant step forward in the treatment of binge eating disorder, but it is far from a perfect solution. While it has helped many patients regain control over their eating habits, its limitations—especially its side effects and inconsistent efficacy—highlight the urgent need for more targeted therapies.
As research continues, the hope is that new medications will emerge to fill this critical gap in mental health care. For now, lisdexamfetamine remains a valuable, albeit imperfect, tool in the fight against binge eating disorder.
