6. Further information
Donepezil belongs to a group of medicines called acetylcholinesterase inhibitors.
Donepezil is used to treat the symptoms of dementia in people diagnosed as having mild to moderately severe Alzheimer's disease.
Do not take Donepezil:
• if you are allergic (hypersensitive) to donepezil hydrochloride or to piperidine derivatives, or any of the other ingredients of Donepezil.

• difficulty passing urine or mild kidney disease.
If you are going to have an operation that requires you to have a general anaesthetic, you should tell your doctor and the anaesthetist that you are taking Donepezil. This is because your medicine may affect the amount of anaesthetic needed.

Donepezil orodispersible tablets are fragile. They should not be pushed through the foil in the blister pack as this will cause damage to the tablet. Do not handle the tablets with wet hands as the tablets may break up. Remove a tablet from the package as follows:
1. Hold the blister at the edges and separate one blister cell from the rest of the blister by gently tearing along the perforations around it.
2. Pull up the edge of the foil and peel the foil off completely.
4. Put the tablet on the tongue as soon as it is removed from the packaging.
In a few seconds it begins disintegrating in the mouth and subsequently can be swallowed with or without water. The mouth should be empty before placing the tablet on the tongue.
The tablet strength you will take may change depending on the length of time you have been taking the medicine and on what your doctor recommends. The maximum recommended dose is 10 mg each night.
