How to take Aricept

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 Aricept is one 5 mg tablet each day.

After 1-month, your doctor will assess your response and may increase your dose to one Aricept 10 mg tablet each day.

However, depending on your condition and how you react to the medicine, your doctor may ask you to take a different dose.

How to take it

Swallow the tablets whole with a full glass of water.

When to take it

Take your medicine 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.

Aricept 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 your medicine 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 your medicine 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.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 131 126 or New Zealand 0800 POISON or 0800 764 766) or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Aricept.

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
  • slow heart beat
  • feeling dizzy or faint
  • difficulty breathing
  • seizures or fits
  • feeling weak

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.

Do not give this medicine to anyone else, even if they have the same condition as you.

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.
