Vyvanse Crash: what it is and how to deal with it


Vyvanse is a prescription drug used to treat attention deficit hyperactivity disorder ADHD and eating disorder. The active substance in Vyvanse is lisdexamfetamine. Vyvanse is an amphetamine and central nervous system stimulant.

People taking Vyvanse may feel tired, irritable, or have other symptoms for several hours after taking the medicine. This is sometimes referred to as the Vyvanse Crash or Vyvanse Comedown. Read on to learn why a Vyvanse crash can happen and what you can do to prevent it from happening.

When you first start taking Vyvanse, your doctor will likely prescribe the lowest possible dose. This limits the side effects that occur as your body adjusts to the drug and helps your doctor determine the lowest effective dose for you. As the day progresses and your medication wears off, a "crash" may occur. For many people, this occurs in the afternoon. This crash can also occur if you forget to take your medication.

Symptoms of this crash may include feeling irritable, anxious, or tired. In most cases, people with ADHD will notice their symptoms return because there aren't enough medications in their system to relieve the symptoms.

What you can do

If you are having issues with the Vyvanse crash, do the following:

Take your medication exactly as your doctor prescribes. You risk a much more serious accident if you take the drug in a higher dose than prescribed, or if you take it in a way that has not been prescribed, e.g. B. by injection.

Take Vyvanse at the same time each morning. Taking this drug regularly will help regulate the levels of the drug in your body. This can help you avoid an accident.

If you are physically dependent, you need to take the drug to feel normal. Discontinuation of the drug leads to withdrawal symptoms, you crave the drug and cannot control your actions when trying to acquire more of it.
