Donepezil (Aricept) is an inexpensive drug used to treat mild to moderate dementia caused by Alzheimer's disease. It is more popular than comparable drugs. It is available in generic and brand versions. Generic donepezil is covered by most Medicare and insurance plans, but some pharmacy coupons or cash prices may be lower.
