Can donepezil cause nightmares?
Donepezil (Aricept) and rivastigmine (Exelon), medications used to treat dementia in Alzheimer’s patients, affect sleep quality — specifically, the quality and amount of dreaming.

When should donepezil be stopped?
These medications should be stopped if the desired effects—stabilizing cognitive and functional status—are not perceived within a reasonable time, such as 12 weeks. In some cases, stopping cholinesterase inhibitor therapy may cause negative effects on cognition and neuropsychiatric symptoms.
