The usual starting dose for Aricept is one 5 mg tablet each day.

When to take it

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.

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.
