Vyvanse (A complete guide)

Vyvanse, or Lisdexamfetamine, is used to treat attention deficit hyperactivity disorder (ADHD) in people over the age of five as well as for moderate to severe binge eating disorder in adults.

Vyvanse is a central nervous system stimulant. 

What is vyvanse used for? 

Vyvanse (Lisdexamfetamine) is prescribed to treat attention deficit hyperactivity disorder (ADHD) as a part of a complete treatment plan, including psychological, social, and other treatments.

This medication enhances the person’s ability to concentrate, stay focused, and stop fidgeting.

Lisdexamfetamine can also be used to treat binge disorder (BED). It is prescribed to help scale back the amount of binge eating days.

This medication is a central nervous system stimulant.

It is thought to work by restoring the balance of certain natural chemicals (neurotransmitters) within the brain.

This medication is not recommended to be used for weight loss purposes due to the danger of serious side effects.

How should Vyvanse be taken?

Read the Medication Guide provided by your doctor before you begin taking lisdexamfetamine and every time you get a refill.

If you have any questions, ask your doctor or pharmacist.

Take this medication with or without food as directed by your doctor, usually once daily in the morning.

The dosage is prescribed based on your medical condition and response to treatment.

Your doctor may adjust your dose to seek out the dose that is right for you.

However, if you have trouble swallowing the capsule, you can open the capsule and pour all of its contents (powder) into a glass of water or fruit juice or mix it in yogurt.

Use a spoon to pull apart any powder that’s stuck together. Stir well until the contents dissolve completely.

Drink or eat the mixture directly. Do not prepare a supply beforehand.

It is normal to see a thin film or coating on the inside of your glass or container after you drink or eat all of the drug.   

If you suddenly stop using this medication, you will have withdrawal symptoms (such as severe tiredness, sleep problems, mental/mood changes like depression).

To prevent withdrawal, your doctor may lower your dose slowly.

Withdrawal is more likely if you have been using lisdexamfetamine for an extended period of time or in high doses.

Tell your doctor or pharmacist directly if you are having withdrawal symptoms.
