Donepezil is a medicine that helps with some types of dementia.
It does not cure dementia. However, it treats some of the symptoms of Alzheimer's disease, Parkinson's disease and dementia with Lewy bodies.
It can also help with mixed dementia. This is when you have more than one type of dementia.
Donepezil is available on prescription only.
It comes as tablets, including tablets that melt in your mouth, and as a liquid that you swallow.
