Donepezil Hydrochloride

What Aricept is and What It is Used For

ARICEPT (donepezil hydrochloride) belongs 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 break down 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.

ARICEPT is for use in adult patients only.

Before You Take Aricept

Do Not Take Aricept

  • if you are allergic (hypersensitive) to donepezil hydrochloride, or to piperidine derivatives, or any of the other ingredients of ARICEPT listed in Further Information

Take Special Care With Aricept

Tell your doctor or pharmacist before starting to take ARICEPT if you have or have had:

  • stomach or duodenal ulcers
  • seizures (fits) or convulsions
  • a heart condition (irregular or very slow heart beat)
  • asthma or other long term lung disease
  • liver problems or hepatitis
  • difficulty passing urine or mild kidney disease

Also tell your doctor if you are pregnant or think you might be pregnant.

Taking Other Medicines

Please tell your doctor or pharmacist if you are taking, or have recently taken, any other medicine. 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 sometime in the future if you continue to take ARICEPT. This is because these medicines may weaken or strengthen the effects of ARICEPT.

Especially 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. aspirin, non-steroidal anti-inflammatory (NSAID) drugs such as ibuprofen, or diclofenac sodium
  • anticholinergics medicines, e.g. tolterodine
  • antibiotics e.g. erythromycin, rifampicin
  • anti-fungal medicine e.g. ketoconazole
  • anti-depressants e.g. fluoxetine
  • anticonvulsants e.g. phenytoin, carbamazepine
  • medication for a heart condition e.g. quinidine, beta-blockers (propanolol 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 ARICEPT. This is because your medicine may affect the amount of anaesthetic needed.

ARICEPT can be used in patients with kidney disease or mild to moderate liver disease. Tell your doctor first if you have kidney or liver disease. Patients with severe liver disease should not take ARICEPT.

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