Donepezil tablets contain the active substance donepezil hydrochloride and belong to a group of medicines called acetylcholinesterase inhibitors.

Donepezil increases the levels of a substance (acetylcholine) in the brain involved in memory function by slowing down the breakdown of acetylcholine.

It is used to treat the symptoms of dementia in people diagnosed as having mild and 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 tablets are for use in adult patients only.


Do not take Donepezil tablets

  • if you are allergic to donepezil hydrochloride, or to piperidine derivatives, or any of the other ingredients of this medicine (listed in section 6). An allergic reaction may include rash, itching, swelling of face, lips, or hands/feet, or breathing difficulties.

  • stomach or duodenal ulcers
  • seizures (fits) or convulsions
  • a heart condition (irregular or very slow heartbeat)
  • asthma or other long term lung disease
  • liver problems or hepatitis. Donepezil tablets can be used in patients with mild to moderate liver disease. Patients with severe liver disease should not take Donepezil tablets.
  • difficulty passing urine or kidney disease. However, Donepezil tablets can be used in patients with kidney disease.

Other medicines and Donepezil tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines that your doctor has not prescribed for you but which you have bought yourself from a chemist/pharmacist. It also applies to medicines you may take some time in the future if you continue to take Donepezil tablets. This is because these medicines may weaken or strengthen the effects of Donepezil tablets.

In particular, it is important to tell your doctor if you are taking any of the following types of medicines:

  • other Alzheimer?s disease medicines, e.g. galantamine
  • pain killers or treatment for arthritis e.g. acetylsalicylic acid, non-steroidal anti-inflammatory drugs (NSAID?s) such as ibuprofen, or diclofenac sodium
  • anticholinergics medicines, e.g. tolterodine
  • antibiotics e.g. erythromycin, rifampicin
  • anti-fungal medicine e.g. ketoconazole, itraconazole
  • anti-depressants e.g. fluoxetine
  • anticonvulsants e.g. phenytoin, carbamazepine
  • medication for a heart condition e.g. quinidine, beta-blockers (propranolol and atenolol)
  • muscle relaxants e.g. diazepam, succinylcholine
  • general anaesthetic
  • medicines obtained without a prescription e.g. herbal remedies

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 tablets. This is because your medicine may affect the amount of anaesthetic needed.

Tell your doctor or pharmacist the name of your caregiver. Your caregiver will help you to take your medicine as prescribed.
