Donepezil is prescribed for people who have demens which is associated with Alzheimer's disease. Dementia is a condition of the brain which causes a gradual loss of mental ability. This includes problems with memory, understanding, judgement, thinking and language. Other problems also commonly develop, such as changes in personality and changes in the way a person interacts with others in social situations.

Donepezil is not a cure for dementia, but it can help with symptoms, particularly those which affect thinking and memory. It works by increasing the level of a natural chemical called acetylcholine. This is a chemical which allows nerve cells in the brain to communicate with each other, and it is known that people with dementia have low levels of it.

Donepezil will be prescribed by a doctor who is a specialist. If you are a caregiver, please read this leaflet on behalf of the person who is receiving donepezil.

Before taking donepezil

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking donepezil it is important that your doctor knows:

  • If you have a heart condition, such as an irregular heartbeat.

  • If you have any problems with your breathing, such as asthma or chronic obstructive pulmonary disease (COPD).

  • If you have any problems with the way your liver works.

  • If you have ever had any of the following: a stomach ulcer, a fit (seizure), or any problems passing urine.

  • Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

  • Om du någonsin har haft en allergisk reaktion mot en medicin.

How to take donepezil

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about donepezil, and it will also provide you with a full list of the side-effects which you could experience from taking it.

  • Your caregiver will help you to take your tablets/medicine exactly as your doctor tells you to. Take one dose every day just before bedtime. It is usual to be prescribed 5 mg daily to take initially, although your dose could be increased to 10 mg daily after the first month. Donepezil can be taken either with or without food.

  • If you have been given the tablets that melt in the mouth, place the tablet on your tongue and allow it to disintegrate in your mouth before you swallow. You may find it helps to have a drink of water before and afterwards.

  • If you have been supplied with donepezil liquid medicine (1 mg/ml), you will also be given a dosing spoon with which to measure out your doses. If you are taking a 5 mg dose, fill the spoon to the 5 ml line; if you are taking a 10 mg dose, fill the spoon to the 10 ml line.

  • If you forget to take a dose, do not worry, just take your dose on the following day as normal. Do not take two doses together to make up for the forgotten dose. If you forget to take donepezil for more than a week, talk with your doctor before you start to take it again, as you may need to re-start your treatment on a lower dose.

Få ut det mesta av din behandling

  • It can take a few weeks before you feel the full benefit of donepezil. Continue to take your doses every day until you are told otherwise by your doctor. Medicines for dementia are usually continued for as long as they are thought to be having a worthwhile effect on symptoms.

  • Your doctor will want to check your progress every few weeks to make sure that you are getting benefit from the treatment. Always try to keep these regular doctor's appointments.

  • Your doctor is likely to advise you not to drink alcohol while you are on this medicine. Drinking alcohol with donepezil can reduce its effectiveness.

  • If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking donepezil. This is particularly important if you are going to need a general anaesthetic.

  • If you buy or take any 'over-the-counter' medicines, always check with a pharmacist that they are safe to take with your prescribed medicines. Some medicines can interfere with the way donepezil works.
