  • Blurred vision
  • Hyperthermia
  • Loss of consciousness
  • Muscle cramps
  • Overactive reflexes
  • Seizures
  • Stroke
  • Heart attack

Overdosing on Vyvanse can lead to long-term problems with kidney and liver health. It may also cause cognitive problems.

What to Do if You Overdose on Vyvanse

If you suspect you or someone you know has overdosed on Vyvanse, seek emergency medical care immediately. Call 911 or poison control or take the person to the emergency room.

Familiarize yourself with Vyvanse overdose symptoms and what to do in case of an overdose. You should also understand the symptoms of serotonin syndrome, a condition closely linked to Vyvanse use.

Staying calm during an overdose event is important, especially if you're having one. Vyvanse is a stimulant that causes an increase in breathing and heart rate. Panicking will only worsen your condition.

Treatment for Vyvanse Overdose

Seek medical attention immediately if you or someone you know has overdosed on Vyvanse. Treatment for an overdose is based on the specific symptoms someone is experiencing. These include:

  • Administration of fluids
  • Activated charcoal to decrease absorption of the drug
  • Benzodiazepines for seizure control and/or sedation
  • Physical restraints if someone poses a danger to self or others
  • Treatment of breathing problems, seizures, trauma, and heart problems

You can survive a Vyvanse overdose, but medical attention is essential. If you mix Vyvanse with other drugs, your chances of survival decrease.

Vyvanse Withdrawal Symptoms

Following an overdose, consider addiction treatment. Checking yourself into a treatment facility can also help you manage uncomfortable withdrawal symptoms.

Withdrawal symptoms include:

  • Agitation
  • Headaches
  • Nausea
  • Vomiting
  • Nervousness
  • Intense cravings

It’s also common for people who have recently overdosed on Vyvanse to experience problems with sleep and appetite. Stopping use can increase appetite and cause severe fatigue. Ideally, a treatment program will address all of these concerns.

When to Seek Treatment for Vyvanse Addiction

Seek addiction treatment after the critical phase of an overdose passes. However, you might want to seek treatment if you notice signs of addiction.

Many people don't realize that ADHD medication can put them at risk for addiction. Even if you're following a prescription, it's still possible to get addicted to Vyvanse.

Treatment Options for Vyvanse Addiction

Treatment options for Vyvanse addiction include:

Treating a co-occurring mental illness is important when dealing with Vyvanse abuse. Doctors must also treat binge eating disorders or help someone find ways to manage their ADHD symptoms without Vyvanse.

How to Prevent Vyvanse Overdose 

There are various ways to reduce and even prevent the risk of a Vyvanse overdose. For example:

  • Only use the drug with a prescription
  • Take only the prescribed dosage
  • Inform your physician about any other medications (over-the-counter (OTC) or prescription) you are taking
  • Never combine the drug with other drugs, especially stimulants like cocaine, methamphetamine, and Ritalin
  • Avoid alcohol

Consider speaking to your doctor about any problems you have with the drug. This is especially important if you want to take more than the prescribed dosage.

What is Vyvanse?

Vyvanse (lisdexamfetamine dimesylate) is a medication that treats attention-deficit hyperactivity disorder (ADHD) and severe binge eating disorder (BED). It is a prescription stimulant with a high risk for misuse and addiction. Because of this, it's classified as a schedule II substance.

Like all stimulants, Vyvanse increases dopamine and norepinephrine in the brain. Dopamine reinforces pleasurable behaviors, and norepinephrine raises the heart rate, blood pressure, and breathing rate.
