When you manage treatment, ask about likely benefit, heart and stomach risks, other drugs, daily dosing, and how you will review progress. Donepezil is an acetylcholinesterase inhibitor for dementia of the Alzheimer's type that raises a brain chemical for mental function but does not cure Alzheimer's. You will give one evening dose, watch for gut, sleep, and pulse changes, and keep the prescriber updated. Bring a full drug list, allergy and ulcer history, and notes on fainting, falls, or slow pulse to the first visit.

What will donepezil do — and not do?
The U.S. National Library of Medicine DailyMed label states it is indicated for dementia of the Alzheimer's type DailyMed label.
It raises a brain chemical involved in mental function but does not cure Alzheimer's. Response varies, and no one can predict benefit for one person in advance. Watch thinking, daily tasks, overall change, and behavior rather than expecting memory to return to normal.
Which health history needs a pre-start check?
The FDA-approved DailyMed prescribing information warns donepezil can affect heart nodes and cause slow pulse, heart block, and fainting FDA-approved prescribing information, mainly with conduction disease. Report fainting or a slow pulse promptly.
It may raise stomach acid and ulcer or bleeding risk. Share history of ulcers, NSAID use, asthma or COPD, seizures, bladder-outflow problems, and use of QT-prolonging or anticholinergic drugs.

- asthma or COPD, seizures, or bladder-outflow problems

What day-to-day changes should I track?
MedlinePlus lists nausea, vomiting, diarrhea, appetite and weight loss, muscle cramps, fatigue, dizziness, sleep problems, and abnormal dreams as common effects MedlinePlus drug information. Note appetite, weight, bowel changes, cramps, energy, dizziness, falls, and sleep each day.
Keep one page with date, dose time, meals, sleep, and any vomiting, diarrhea, dreams, or dizziness. Call promptly for fainting, very slow pulse, severe vomiting or diarrhea, or a fall.
How do I give the evening dose?
The usual start is 5 mg once daily in the evening before bed. The doctor may raise it to 10 mg daily for mild-to-moderate disease and up to 23 mg daily for moderate-to-severe disease. Give one dose at about the same time each evening and never double a missed dose.
Swallow the 23-mg tablet whole. Let orally disintegrating tablets dissolve, then drink water. Call the doctor before restarting after seven or more missed days.
What about surgery, other drugs, and staying on it?
Tell surgeons and dentists about donepezil before anesthesia because it can strengthen succinylcholine-type muscle relaxation. It can also oppose anticholinergic drugs and add to cholinergic agonist effects. Bring every prescription, over-the-counter product, and supplement for review. The UK National Institute for Health and Care Excellence NG97 advises regular review of benefit.
Continue only with worthwhile cognitive, functional, global, or behavioral gain. Do not stop for severity alone; any stop needs discussion among clinician, patient, and carer. Bring your dose log, side-effect notes, and full drug list to each visit. Ask what improved, what worsened, and whether the current dose still earns its place.
