How to take Donepezil AN
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the packaging, ask your doctor or pharmacist for help.
How much to take
The usual starting dose for Donepezil AN is one 5 mg tablet each day.
After 1-month, your doctor will assess your response and may increase your dose to one 10 mg tablet a day.
However, depending on your condition and how you react to the medicine, your doctor may ask you to take some other dose.
How to take it
Swallow the tablets whole with a full glass of water.
When to take it
Take the tablet every night just before you go to bed. Taking it at the same time each day will have the best effect. It will also help you remember when to take it. Donepezil AN can be taken with or without food.
How long to take it
Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
It may take several weeks for Donepezil AN to take effect, so do not be discouraged if you do not see an improvement straight away.
If you forget to take it
If you forget to take a tablet, just take one tablet the following day at the usual time then continue as normal.
Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you forget to take it for more than 1-week, call your doctor before taking any more.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
In case of an overdose
Immediately telephone your doctor or the Poisons Information Centre – the telephone number in Australia is 13 11 26 or go to Accident and Emergency (Casualty) at your nearest hospital, if you think that you or anyone else may have taken too much Donepezil AN.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of an overdose may include feeling sick in the stomach, vomiting, increased sweating or saliva production. You may also have a slow heart beat, feel dizzy, have trouble breathing, faint, have fits, feel weak or not be able to control your bowel motions or passing of urine.

Do not use Donepezil AN to treat any other complaints unless your doctor says to.

In addition, Alzheimer’s disease may affect your ability to drive or operate machinery. Ask your doctor whether it is safe for you to continue to drive or operate machinery.
