Aricept (donepezil) Full Prescribing Information

Why is this drug prescribed?

Aricept is one of the few drugs that can provide some relief from the symptoms of early Alzheimer's disease. (Cognex, Exelon, and Reminyl are others.) Alzheimer's disease causes physical changes in the brain that disrupt the flow of information and interfere with memory, thinking, and behavior. Aricept can temporarily improve brain function in some Alzheimer's sufferers, although it does not halt the progress of the underlying disease.

Most important fact about this drug

To maintain any improvement, Aricept must be taken regularly. If the drug is stopped, its benefits will soon be lost. Patience is in order when starting the drug. It can take up to 3 weeks for any positive effects to appear.

How should you take this medication?

Aricept should be taken once a day just before bedtime. Be sure it's taken every day. If Aricept is not taken regularly, it won't work. It can be taken with or without food.

--If you miss a dose...

Make it up as soon as you remember. If it is almost time for the next dose, skip the one that was missed and go back to the regular schedule. Never double the dose.
