Vyvanse has a boxed warning about a risk of drug misuse and dependence. This is a serious warning from the Food and Drug Administration (FDA). A boxed warning alerts doctors and patients about drug effects that may be dangerous.

Taking drugs called stimulants may lead to drug misuse and physical dependence. (Vyvanse is a type of stimulant.) Misuse, which is also called abuse, refers to taking a drug in a different way than how your doctor prescribed. With physical dependence, you need to take a drug to feel as you usually do.

Vyvanse should not be taken recreationally (without a medical purpose). Misusing Vyvanse, as well as taking it as prescribed, can sometimes lead to addiction.

In fact, Vyvanse is a schedule II controlled substance, which means the FDA regulates it closely. It’s important to store Vyvanse in a safe place. This helps prevent others from misusing the drug. It’s illegal to give or sell Vyvanse to someone else.

Symptoms of misuse

Other symptoms of Vyvanse misuse are similar to those of overdose. For details, see “Vyvanse and overdose” below.

You can also talk with your doctor or pharmacist about symptoms of Vyvanse misuse.

Symptoms of withdrawal

Because Vyvanse can cause you to become dependent upon it, you may have withdrawal symptoms if you stop taking the drug. These can include extreme fatigue and depression. It’s important that you do not stop taking Vyvanse unless you first talk with your doctor.

Suicide prevention

If you know someone at immediate risk of self-harm, suicide, or hurting another person:

  • Ask the tough question: “Are you considering suicide?”
  • Listen to the person without judgment.
  • Call 911 or the local emergency number, or text TALK to 741741 to communicate with a trained crisis counselor.
  • Stay with the person until professional help arrives.
  • Try to remove any weapons, medications, or other potentially harmful objects.

If you or someone you know is having thoughts of suicide, a prevention hotline can help. The National Suicide Prevention Lifeline is available 24 hours per day at 800-273-8255. During a crisis, people who are hard of hearing can use their preferred relay service or dial 711 then 800-273-8255.
