How to use lisdexamfetamine:

Use lisdexamfetamine as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Lisdexamfetamine comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get lisdexamfetamine refilled.
  • Take lisdexamfetamine by mouth in the morning with or without food.
  • Swallow lisdexamfetamine whole. Do not break, crush, or chew before swallowing. If you cannot swallow the capsule whole, you may open it and mix the contents with yogurt, water, or orange juice. If needed, a spoon may be used to break apart any powder that is stuck together. Stir well until completely mixed. Eat or drink the mixture right away. Do not store the mixture for future use. It is normal to see a filmy coating on the inside of your glass or container after you take lisdexamfetamine.
  • Take lisdexamfetamine on a regular schedule to get the most benefit from it. Taking lisdexamfetamine at the same time each day will help you remember to take it.
  • If you miss a dose of lisdexamfetamine, take it as soon as possible if you remember that morning. If it is past noon, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use lisdexamfetamine.

Important safety information:

  • Lisdexamfetamine may cause drowsiness, dizziness, blurred vision, or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use lisdexamfetamine with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

If you have a heart defect or other serious heart problem, talk with your doctor about other therapies to treat your condition.
  • Before you start any new medicine, check the label to see if it has a decongestant in it. If it does or if you are not sure, check with your doctor or pharmacist.

When used for long periods of time or at high doses, lisdexamfetamine may not work as well and may require higher doses to obtain the same effect as when originally taken. This is known as TOLERANCE. Talk with your doctor if lisdexamfetamine stops working well. Do not take more than prescribed.

Some people who use lisdexamfetamine for a long time may develop a need to continue taking it. People who take high doses are also at risk. This is known as DEPENDENCE or addiction.
