Donepezil is used to treat dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and may cause changes in mood and personality) associated with Alzheimer's disease (AD; a brain disease that slowly destroys the memory and the ability to think, learn, communicate and handle daily activities). Donepezil is in a class of medications called cholinesterase inhibitors. It improves mental function (such as memory, attention, social interaction, reasoning and language abilities, and ability to perform activities of daily living) by increasing the amount of a certain naturally occurring substance in the brain. Donepezil may improve the ability to think and remember or slow the loss of these abilities in people who have AD. However, donepezil will not cure AD or prevent the loss of mental abilities at some time in the future. More info »

About This Data

ProPublica obtained prescribing data from Medicare’s prescription drug benefit, known as Part D, under the Freedom of Information Act. The data for 2011 includes nearly 1.2 billion prescriptions written by 1.6 million doctors, nurses and other providers. This database lists about 364,000 of those providers who wrote 50 or more prescriptions for at least one drug that year. About three-fourths went to patients 65 and older; the rest were for disabled patients. Methodology »

Caveats
  • No comparisons are shown if 10 or fewer prescribers in the state share this specialty.
  • The list of top drugs includes only those for which this provider wrote 50 or more prescriptions, but all prescriptions are counted in the summary totals at the top.
  • The calculation of “Risky Drugs to Seniors” does not include drugs for which a provider wrote 11 or fewer prescriptions because Medicare redacted the information to protect patient privacy.
  • Comparisons do not take into account the medical conditions of patients. Medications for certain conditions do not have generic alternatives, so patients would receive more expensive brand name drugs.
  • This provider's address and specialty information was last updated on May 8, 2013.
  • Comparisons are based on each provider’s current address, not necessarily where he or she worked during the time period covered in this database.
