Ask what benefit to expect, how you will measure it, and which health conditions or medicines could make donepezil risky. Also ask how dosing will increase, which side effects require attention, and when treatment will be reviewed. Donepezil is a prescription medicine for dementia caused by Alzheimer's disease. It can be used in mild, moderate, or severe disease, but it does not cure Alzheimer's or stop its progression, according to the July 2025 DailyMed prescribing information.

What benefit should we expect?
Ask which changes would count as a meaningful benefit for this person. Donepezil may improve mental function or everyday tasks for some people, while others show little observable improvement. Alzheimer's will still worsen over time.
Choose a few concrete abilities to watch before treatment begins. Examples might include following conversations, completing a familiar task, or needing fewer reminders. Record the starting point so later changes are easier to describe. Useful questions include:.
- Which abilities are we hoping to maintain or improve?
- How long will we observe before assessing the response?
- Who should report changes if the person cannot judge them reliably?
- What would make us reconsider the treatment plan?
Could my health history raise the risks?
Tell the prescriber about any allergy to donepezil or other piperidine derivatives. A known allergy means donepezil should not be started. Heart history deserves particular attention.
Ask whether slow, fast, or irregular heartbeats affect the decision, because donepezil can cause a slow heartbeat, heart block, or fainting—even without known conduction disease. Also discuss: These conditions matter because donepezil's effects may increase stomach acid, worsen certain lung problems, contribute to convulsions, or obstruct bladder outflow. The DailyMed safety warnings also call for monitoring gastrointestinal bleeding risk in people with prior ulcers or aspirin or NSAID use.
- A previous stomach ulcer
- Aspirin or nonsteroidal anti-inflammatory drug use
- Asthma or obstructive lung disease
- Seizures
- Trouble urinating
Have all medicines and procedures been reviewed?
Bring a complete list of prescription medicines, over-the-counter products, and planned procedures. Ask specifically whether any medicine has anticholinergic effects, because those effects can interfere with donepezil.
Tell surgeons and dentists that donepezil is being taken. During anesthesia, it can exaggerate the muscle relaxation caused by succinylcholine-type drugs, as described in DailyMed's interaction and anesthesia guidance. Before leaving the appointment, ask:.
- Does anything on the medication list conflict with donepezil?
- Should any planned surgery or dental procedure affect timing?
- Who should be contacted if a new medicine is prescribed later?
What is the dosing and side-effect plan?
Donepezil generally starts at 5 mg once daily. Increasing to 10 mg should wait four to six weeks, while 23 mg should wait until the person has taken 10 mg for at least three months.
Higher doses more often cause nausea, vomiting, diarrhea, insomnia, muscle cramps, fatigue, appetite loss, and weight loss, according to the DailyMed dosing information. Ask what symptoms should prompt a call before the next scheduled visit. A simple monitoring note can track:.
- The current dose and date started
- Appetite and weight changes
- Nausea, vomiting, or diarrhea
- Sleep problems, cramps, or fatigue
- Fainting or heartbeat concerns
