Living with Binge Eating Disorder (BED) feels like being trapped in a loop. You’re fine, you’re fine, and then suddenly, you aren’t. It’s an overwhelming, compulsive drive to consume large quantities of food, often accompanied by a crushing sense of shame afterward. For many, the cycle feels unbreakable. But since 2015, there has been a specific pharmaceutical tool in the shed: lisdexamfetamine dimesylate. Most people just call it Vyvanse. Getting prescribed Vyvanse for binge eating isn't about just asking for a "diet pill"—because it isn't one. It’s a serious central nervous system stimulant, and the process of getting it involves navigating a very specific medical diagnosis.
Why Vyvanse is the Only Game in Town (For Now)
It’s actually kinda wild when you think about it. Despite BED being the most common eating disorder in the United States—affecting more people than anorexia and bulimia combined—Vyvanse remains the only FDA-approved medication specifically for moderate-to-severe Binge Eating Disorder. Doctors sometimes prescribe other things off-label, like Topamax or various SSRIs, but Vyvanse is the heavyweight in the room.
It works on your brain chemistry, specifically targeting dopamine and norepinephrine. In people with BED, the reward system is often out of whack. The "stop" signal doesn't fire correctly. Vyvanse helps bridge that gap. But here is the thing: doctors don't just hand it out because you feel like you overeat on the weekends. There’s a massive difference between "overeating" and a clinical diagnosis of BED. To get prescribed Vyvanse for binge eating, you have to meet the criteria laid out in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders).
The Diagnosis: Are You Actually Eligible?
Before you even book the appointment, you should know what a physician is looking for. They aren't looking for "I ate too much pizza." They are looking for episodes that happen at least once a week for three months. These episodes involve eating much more rapidly than normal, eating until uncomfortably full, and eating large amounts when not physically hungry.
Most importantly? The distress.
If you don't feel disgusted, depressed, or guilty afterward, a doctor likely won't categorize it as BED. Honestly, the emotional tax is usually the biggest indicator for clinicians. When you sit down with a psychiatrist or a primary care physician, you’ve got to be brutally honest about these moments. If you downplay the behavior because you're embarrassed, they might just think you have a slow metabolism or need a nutritionist. That won't get you the help you actually need.
The ADHD Connection
Interestingly, Vyvanse was an ADHD med long before it was a BED med. There is a huge overlap here. Many people who struggle with binge eating also have undiagnosed ADHD. The impulsivity, the search for a dopamine hit, the inability to focus on "fullness" cues—it’s all linked. If you already have an ADHD diagnosis, getting prescribed Vyvanse for binge eating might be a more straightforward conversation with your current provider. They already know your heart health and your history with stimulants.
The Appointment: How to Talk to Your Doctor
Don't go in and say, "I saw a TikTok about Vyvanse and I want it."
Doctors hate that. It sets off red flags for drug-seeking behavior, especially since Vyvanse is a Schedule II controlled substance. Instead, focus on the symptoms and the functional impairment. Tell them how the binging affects your life. Does it make you miss work? Do you avoid social situations? Are you spending money you don't have on delivery apps in the middle of the night?
You might say something like: "I've been struggling with these episodes of loss of control with food. It happens about twice a week, and I feel incredibly guilty afterward. I’ve tried therapy/dieting/willpower, and nothing is stopping the urge. I’ve read about the FDA approval for Vyvanse for BED and I’m wondering if I’m a candidate."

That shows you’ve done your homework but you're still deferring to their expertise. It’s a partnership.
What No One Tells You About the Side Effects
Look, it isn't a miracle drug without a cost. Because it's a prodrug—meaning your body has to metabolize it into its active form (dextroamphetamine)—it lasts a long time. This is great for preventing binges in the evening, but it can be a nightmare for sleep.
Dry mouth is almost a guarantee. You’ll be drinking water like you're lost in a desert.
Then there’s the "crash." When the meds wear off, some people get "Vyvanse rage" or a deep "slump" where their mood bottoms out. Your doctor needs to know if you have a history of heart issues or high blood pressure, too. Stimulants can rev your heart rate up, and if you already have underlying cardiovascular issues, Vyvanse might be off the table entirely.
The Cost and Insurance Hoops
This is where things get annoying. Even with a valid reason for being prescribed Vyvanse for binge eating, your insurance company might put up a fight. They often require "Prior Authorization."

This basically means your doctor has to write a letter to the insurance company saying, "Yes, they really need this, and no, we haven't found a cheaper way to fix it." Sometimes they’ll make you try "step therapy," which is a fancy way of saying they want you to try cheaper, older drugs first.
Since the patent for Vyvanse expired recently, generic versions (lisdexamfetamine) are now available. This has made it significantly cheaper for most people, though shortages have plagued the market for the last year. You might get the prescription only to find out your local pharmacy is out of stock. It’s a frustrating reality of the current medical landscape.
It’s Not a Weight Loss Drug
We have to be clear about this. While some people lose weight on Vyvanse because it suppresses appetite, that is NOT why it is prescribed for BED. The goal isn't to make you thin; it’s to stop the binging behavior. If you go into an office and say you want it to lose twenty pounds for a wedding, you aren't getting it.
Clinical trials, like those published in JAMA Psychiatry, showed that participants on Vyvanse had significantly fewer binge days per week compared to those on a placebo. That is the metric of success. Not the scale.
Real World Expectations
If you do get the prescription, the starting dose is usually 30 mg. Your doctor might titrate you up to 50 mg or 70 mg depending on how you respond. You should notice a "quieting" of the food noise in your head. That constant "eat, eat, eat" background chatter usually fades.

But it doesn't fix the underlying emotional stuff. If you binge because of childhood trauma or intense work stress, the pill might stop the physical act, but the feelings are still there. Most experts, like those at the National Eating Disorders Association (NEDA), recommend combining medication with Cognitive Behavioral Therapy (CBT) or Dialectical Behavior Therapy (DBT).
Steps to Take Right Now
If you are ready to pursue this, don't just wait for it to get better on its own. It rarely does.
- Keep a Log: For one week, track your binge episodes. Don't judge yourself. Just record when they happen, what triggered them, and how you felt. This is data for your doctor.
- Check Your Heart: If you haven't had a physical recently, get one. Check your blood pressure. A doctor will be much more comfortable prescribing a stimulant if they know your ticker is in good shape.
- Find the Right Provider: A general practitioner can prescribe Vyvanse, but a psychiatrist who specializes in eating disorders is usually a better bet. They understand the nuances of BED far better than a standard family doc might.
- Research Generics: Check your insurance formulary to see if lisdexamfetamine is covered and what the copay is. Being prepared for the cost prevents "pharmacy counter shock."
- Verify the Diagnosis: Use the DSM-5 criteria to honestly assess your situation. If you meet the "once a week for three months" threshold with loss of control, you have a clinical basis for the conversation.
Taking the step to get prescribed Vyvanse for binge eating is a move toward reclaiming your time and your mental energy. It’s about more than just food; it’s about getting your life back from a cycle that feels impossible to break alone. Reach out to a professional and start the dialogue. You don't have to white-knuckle your way through this.
