Rivastigmine is used to treat confusion (dementia) related to Alzheimer's disease and to Parkinson's disease. Rivastigmine does not cure either of these diseases, but it may improve memory, awareness, and the ability to perform daily functions. This medication works by restoring the balance of natural substances (neurotransmitters) in the brain.
Read the Patient Information Leaflet if available from your pharmacist before you start taking rivastigmine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
