Generic Name: rivastigmine (RIV-a-STIG-meen)
Brand Name: Exelon
Rivastigmine is used for:
Treating mild to moderate dementia (eg, impairment of memory or judgment, abstract thinking, changes in personality) in patients with Alzheimer or Parkinson disease.
Rivastigmine is a cholinesterase inhibitor. It works by increasing the amount of a certain substance (acetylcholine) in the brain, which may help reduce symptoms of dementia in patients with Alzheimer disease.
Do NOT use rivastigmine if:
- you are allergic to any ingredient in rivastigmine or to carbamate derivatives (eg, meprobamate)
- you are taking another form of rivastigmine (eg, patch, solution) or another cholinesterase inhibitor (eg, donepezil)
Contact your doctor or health care provider right away if any of these apply to you.
Before using rivastigmine:

Some MEDICINES MAY INTERACT with rivastigmine. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen) because the risk of stomach or bowel bleeding may be increased

- Anticholinergics (eg, scopolamine) because their effectiveness may be decreased by rivastigmine
This may not be a complete list of all interactions that may occur. Ask your health care provider if rivastigmine may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
