These are medications for which memory loss appears among the most-reported events in FDA adverse event reports. A report does not mean the drug caused the event. Report counts largely reflect how widely a drug is used and how often events are reported; they cannot be used to compare or rank drugs by risk. This list shows drugs where this event is among their top reported reactions, not every drug ever associated with it. This information is not medical advice. Do not stop or change a medication based on this data; discuss any concerns with your healthcare provider. Data from the FDA Adverse Event Monitoring System (AEMS), formerly FAERS, via OpenFDA.
