What Donepezil Oral Solution is and what it is used for


Donepezil Hydrochloride 2 mg/ml Oral Solution (referred to in this leaflet as Donepezil Oral
Solution) contains the active ingredient Donepezil Hydrochloride. It belongs to a group of medicines
called acetylcholinesterase inhibitors. These work by slowing the breakdown of acetylcholine (a
substance in the brain involved in memory function).
Donepezil Oral solution is used to treat the symptoms of dementia in people diagnosed as having
mild to moderately severe Alzheimer’s disease. The symptoms include increasing memory loss,
confusion and behavioural changes. As a result, sufferers of Alzheimer’s disease find it more and
more difficult to carry out their normal daily activities.
Donepezil Oral Solution is for use in adult patients only.
