Pharmacologic—

Cholinesterase Inhibitor, Centrally Acting

Uses of This Medicine:

Rivastigmine patch is used to treat dementia (memory loss) associated with mild, moderate, or severe Alzheimer's disease, or mild to moderate dementia associated with Parkinson's disease. Rivastigmine will not cure these diseases and it will not stop these diseases from getting worse. However, rivastigmine can improve thinking ability in some patients with these diseases.

In Alzheimer's disease, many chemical changes take place in the brain. One of the earliest and biggest changes is that there is a decrease in a chemical called acetylcholine (ACh). ACh helps the brain to work properly. Rivastigmine is an acetylcholinesterase inhibitor. It slows the breakdown of ACh, so it can build up and have a greater effect. However, as Alzheimer's disease gets worse, there will be less and less ACh, so rivastigmine may not work as well.

This medicine is available only with your doctor's prescription.

Proper Use of This Medicine:

To use the skin patch:

  • Apply the patch right away after removing it from the protective pouch. Do not cut it into smaller pieces and do not touch the sticky surface of the patch.
  • Apply the patch to a clean, dry, and hairless skin area on your upper or lower back, upper arm, or chest. Do not put the patch over rashes, cuts, or irritated skin. Avoid putting the patch on areas where it could be rubbed off by tight clothing.
  • Do not use the patch if the pouch seal is broken or the patch is cut, damaged, or changed in any way.
  • Press the patch firmly in place for 30 seconds with the palm of your hand to make sure that the edges of the patch stick well.
  • The patch should stay in place, even when you are showering, bathing, or swimming. Apply a new patch if it falls off.
  • After 24 hours, remove the patch. 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 14 days. Do not leave the patch on for more than 24 hours. It will not work as well after that time and it may irritate your skin.
  • After removing a used patch, fold the patch in half with the sticky sides together. Place the folded, used patch in its protective pouch. Make sure to dispose of it out of the reach of children and pets.
  • Try to change the patch at the same time each day. If you forget to change the patch at the usual time, remove the patch you are wearing and put on a new patch. After that, apply a fresh patch at the usual time on the next day.
  • Do not put cream, lotion, ointment, oil, or powder on the skin area where the patch will be placed.
  • Do not touch your eyes after you touch the patch.
  • Do not expose the patch to direct sources of heat, such as heating pads, electric blankets, heat lamps, saunas, hot tubs, heated water beds, or direct sunlight for long periods of time.
  • Make sure you wash your hands with soap and water before and after applying the patch.

Do not stop using this medicine without asking your doctor. If you have not used your medicine for several days in a row, do not start using it again without talking to your doctor first. You may need to start the medicine again using a lower dose.

Dosing—

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.

However, the dose is usually not more than one 13.3 mg patch per day.
      • Children—Use and dose must be determined by your doctor.

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.

If you go 3 days in a row or longer without wearing a patch, do not apply a new one until you have talked to your doctor. You might need to go back to a lower dose.

Storage—

Store the patches at room temperature in a closed container, away from heat, moisture, and direct light.

Precautions While Using This Medicine:

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and to check for unwanted effects.

This medicine may cause serious skin reactions such as blistering, burning, crusting, dryness, flaking, itching, scaling, severe redness, soreness, or swelling of the skin. Call you doctor right away if these skin reactions spread beyond the patch size, if they get worse, or if symptoms do not improve within 48 hours after removing the patch.

Having more than one patch on your body at the same time can cause you to get too much of this medicine. Make sure you remove the used patch before wearing a new one to decrease your risk of having serious side effects. If you accidentally use more than one patch at a time, call your doctor right away.

This medicine may cause nausea, severe vomiting, loss of appetite, diarrhea, and weight loss. Talk with your doctor before using this medicine if you have any concerns.
