Drug identifiers, or pill identifiers, are tools used to identify Exelon (rivastigmine) or other drugs if shape and color or imprints on pills are known. Some are used to find images or pictures of pills, capsules, or tablets if drug name is known. Drug identification is helpful to identify Exelon when it has been separated from its original packaging. Most drug identifiers display the drug image or photo with the name of the medication. Exelon is used to treat Alzheimer's disease and mild dementia due to Parkinson's disease.
