1 What Donepezil tablets are and what they are used for

Donepezil tablets belong to a group of medicines called acetylcholinesterase inhibitors. Donepezil tablets are used to treat the symptoms of dementia in people diagnosed as having mild to moderately severe Alzheimer’s disease. Donepezil tablets are for use in adult patients only.

2 What you need to know before you take Donepezil tablets

Do not take Donepezil tablets if you are

  • allergic to donepezil hydrochloride, piperidine derivatives or to any of the other ingredients of this medicine ((listed in section 6)

Warnings and precautions

Treatment with Donepezil tablets should only be started and supervised by a doctor with experience in diagnosing and treating Alzheimer’s dementia.

Talk to your doctor or pharmacist before taking Donepezil tablets if you:

  • have ever had stomach or duodenal ulcers, or if you are taking non steroidal anti-inflammatory drugs (NSAIDS)
  • have ever had a seizure. Donepezil may have the potential to cause fits or seizures. Your doctor will monitor your symptoms.
  • have a heart condition (especially if you have an irregular heart beat, sick sinus syndrome, or other conditions that affect the rhythm of the heart), as donepezil may slow down your heart rate.
  • have asthma or other long term lung disease
  • have ever had liver disease
  • have difficulty passing urine
  • are going to have an operation that requires you to have a general anaesthetic, as the dose of the medication used in anaesthesia may need to be adjusted.

Children and adolescents

Donepezil tablets are not recommended for children and adolescents below the age of 18 years.

  • anti-depressants such as fluoxetine
  • anticonvulsants, such as phenytoin or carbamazepine
  • medication for a heart condition, such as quinidine, or high blood pressure, such as beta blockers
