Uncommon card · No. 75596

Donepezil, sold under the brand name Aricept among others, is a medication used to treat dementia of the Alzheimer's type. It appears to result in a small benefit in mental function and ability to function. Use, however, has not been shown to change the progression of the disease. Treatment should be stopped if no benefit is seen. It is taken by mouth or via a transdermal patch. Donepezil is a centrally acting reversible acetylcholinesterase inhibitor and structurally unrelated to other anticholinesterase agents. Common side effects include nausea, trouble sleeping, aggression, diarrhea, feeling tired, and muscle cramps. Serious side effects may include abnormal heart rhythms, urinary incontinence, and seizures. Donepezil was approved for medical use in the United States in 1996. It is available as a generic medication. In 2023, it was the 126th most commonly prescribed medication in the United States, with more than 4 million prescriptions.
