Let's take a minute to talk about your medication. This is an Exelon patch. It may help patients with conditions like Parkinson's or Alzheimer's with their ability to think, remember, and do daily tasks. You should know it can take several weeks to begin working. Some side effects could occur, like drowsiness, dizziness, weakness or fainting. So, wait until you know how the patch affects you or your loved-one before doing dangerous activities, like driving. It could cause weight loss or a reduced appetite. The most common side effects include nausea, vomiting, or diarrhea. You should let the doctor know if these or other effects happen. You should apply the skin patch exactly as instructed by the doctor. You should change the patch every 24 hours, at the same time each day. You should select a site on the body that has skin which is healthy, dry, hairless and freshly clean. Also, select a site that has not had a patch on it in at least 14 days. This is important to avoid skin irritation. To reduce serious side effects, it is very important that only 1 patch is worn at a time. Also, avoid heat sources like heating pads, electric blankets, and direct sunlight. Always check with your doctor or pharmacist before taking other medicines. Also, ask about how to handle a missed dose or a patch that falls off. When you remove a used patch, fold the adhesive sides together to seal it before you throw it away. Always keep new and used patches out of the reach of children and pets. Be sure to wash your hands anytime after handling the patch. For best results, you should read the Medication Guide for more information. Also, ask about patient support services that are available.
