Quick overview

Lisdexamfetamine Capsule is a central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD) in adults and children aged 6 and older, as well as moderate to severe binge eating disorder in adults. It works by affecting brain and nerve chemicals linked to hyperactivity and impulse control. It is taken once daily in the morning and must be used exactly as prescribed, since it carries risks of misuse, dependence, and several serious side effects.

What is Lisdexamfetamine Capsule

How Lisdexamfetamine Capsule works

Lisdexamfetamine is a stimulant. In ADHD it can help increase attention and decrease impulsiveness and hyperactivity, and in binge eating disorder it can help reduce how often someone overeats. The exact way it works in the body is not fully known. After it is taken, the body converts it into a related substance that acts on the central nervous system.

Lisdexamfetamine Capsule dosage

Take this medicine once a day in the morning. Avoid taking it in the afternoon, because taking it later in the day can make it harder to sleep at night. Capsules can be swallowed whole, or with or without food. Do not split, crush, chew, or divide the capsule, and do not try to take less than a full capsule.

If you cannot swallow the capsule whole, you can open it and mix the contents with yogurt, water, or orange juice, and take the mixture right away rather than saving it for later. If a chewable tablet form is used instead, it must be chewed completely before swallowing and should not be swallowed whole.

Do not take this medicine unless it has been prescribed to you, and take it exactly as prescribed. Do not share this medicine with anyone else, even if they have the same condition.

If you miss a dose, take it as soon as you remember, but avoid taking it late in the day since this can make it harder to sleep; do not take a double or extra dose to make up for a missed one.

People age 65 and older may be at greater risk for some side effects, so talk with your healthcare provider about this if it applies to you.
