    Before Using

    In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

    Allergies

    Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

    Pediatric

    Appropriate studies have not been performed on the relationship of age to the effects of dextroamphetamine transdermal patch in children younger than 6 years of age. Safety and efficacy have not been established.

    Geriatric

    Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of dextroamphetamine transdermal patch in the elderly. However, elderly patients are more likely to have age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving dextroamphetamine.

    Proper Use

    Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.

    This medicine should come with a Medication Guide and patient instructions. Read and follow these instructions carefully. Ask your doctor if you have any questions. Ask your pharmacist for the Medication Guide if you do not have one.

    To use the skin patch:

    • Make sure you wash your hands with soap and water after applying the patch. Do not use a hand sanitizer in place of soap and water.
    • Do not use the patch if it is cut or damaged. When handling the skin patch, be careful not to touch the adhesive (sticky) surface with your hand. The adhesive part of the system contains some dextroamphetamine which can be absorbed into your body too fast through the skin of your hand. Wash your hands with soap and water if you accidentally touch the sticky side of the patch. Apply the patch right away after removing it from the protective pouch.
    • Apply the patch 2 hours before the needed effect and remove it after 9 hours. Do not wear patches for longer than 9 hours a day total. Choose a different place on your skin to apply the new patch. Do not put a new patch in the same place for at least one day (24 hours). Do not leave the patch on for more than 9 hours. It will not work as well after that time and it may irritate your skin.
    • Apply the patch to a clean, dry, and healthy skin area on your chest, hip, flank (side of the waist), upper arm, or upper back. Choose an area that is free of scars, cuts, burns, rashes, that has very little to no hair, or any other skin irritation. Avoid putting the patch on areas where it could be rubbed by tight clothing (eg, waistbands or straps). Do not shave the skin where you will apply the patch. You may cut the hair with a pair of scissors.
    • Remove the liner covering the sticky side of the skin patch. Place the sticky side against the skin. Slowly peel the clear liner while applying gentle pressure with fingers of your other hand to smooth the patch firmly in place, press the patch firmly with the palm of your hands to make sure there is good contact with your skin, especially around the edges of the patch.
    • Do not put lotion, gel, oil, or powder on the skin area where the patch will be placed. Do not expose the application site to direct heat (including hair dryer, heating pad or electric blankets, heat lamps, saunas, hot tubs, and heated water beds).
    • The patch might come off if you go swimming or take a bath or shower. If the edges lift, smooth down the patch and press firmly with the palm of your hand. Do not reapply with dressings, tape, or other adhesives. If the patch falls off after applying it, throw it away and apply a new patch in a different area.
    • You may apply oil-based product or water and soap to remove any glue on your skin.

    The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

    The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

    Missed Dose

    If you forget to wear or change a patch, put one on as soon as you can. If it is almost time to put on your next patch, wait until then to apply a new patch and skip the one you missed. Do not apply extra patches to make up for a missed dose.

    Storage

    Keep out of the reach of children.

    Do not keep outdated medicine or medicine no longer needed.

    • A need to increase the dose to receive the effects of the medicine.
    • Withdrawal effects (for example, mental depression, nausea or vomiting, stomach cramps or pain, trembling, unusual tiredness or weakness) that occur after the medicine is stopped.

    Check with your doctor right away if you or your child have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there.
