Why is Exelon prescribed?
Exelon is used in the treatment of mild to moderate Alzheimer's disease. Alzheimer's disease causes physical changes in the brain that disrupt the flow of information and interfere with memory, thinking, and behavior. By boosting levels of the chemical messenger acetylcholine, Exelon can temporarily improve brain function in some Alzheimer's sufferers, though it does not halt the progress of the underlying disease. Exelon may become less effective as the disease progresses.

Special warnings about Exelon
Exelon often causes nausea and vomiting, especially at the beginning of treatment. The problem is more likely in women, but it can lead to significant weight loss in both women and men. Tell your doctor immediately if these side effects occur.
The chance of severe vomiting increases when Exelon is given after an interruption of several days. Do not start giving the drug again without first checking with the doctor. Dosage may need to be reduced to the lowest starting level.
Exelon may aggravate asthma and other breathing problems and can increase the risk of seizures. Other drugs of its type are also known to increase the chance of ulcers, stomach bleeding, and urinary obstruction, although these problems have not been noted with Exelon. Drugs in this category can also slow the heartbeat, possibly causing fainting in people who have a heart condition. Contact your doctor if any of these problems occur.
Exelon has not been tested in children.
