A donepezil symptom diary should record each dose, missed doses, medicine changes, daily abilities, possible side effects, pulse, weight, falls, and urgent warning signs. It should also mark the start date and every dose increase so clinicians can see when changes occurred. Donepezil treats symptoms of Alzheimer-type dementia but does not cure the disease. The diary's purpose is to reveal useful patterns—not to prove that every improvement or decline was caused by the medicine.

Build a clear medication timeline
For each day, record the donepezil dose, the time it was taken, and whether it was missed. Note the reason for a missed dose if known, but do not rely on memory to fill gaps later. Create a separate entry for every new prescription medicine, over-the-counter product, vitamin, or supplement.
Include when it started or stopped. The NHS advises checking these products because interactions may change donepezil's effectiveness or side-effect risk in its guidance on donepezil and other medicines. Mark the date donepezil was started and every dose increase. Add any vomiting or other new symptoms beside those dates, since close observation is particularly important at treatment initiation and after an increase.
Record changes in thinking and daily life
Use brief, concrete observations rather than broad judgments such as "better" or "worse." Track changes in memory, concentration, anxiety, motivation, and the ability to complete everyday tasks. The NHS identifies these as areas clinicians may consider when deciding whether donepezil is helping in its patient guidance.
Useful entries describe what happened and how much help was needed: Avoid turning one difficult day into a verdict. Repeated examples are more informative because donepezil does not help everyone equally, and dementia itself can continue to change.
- Remembered a planned visit without a reminder.
- Followed the steps for dressing with one prompt instead of three.
- Lost track halfway through preparing breakfast.
- Joined a familiar activity after encouragement.
- Appeared anxious during a task that was previously manageable.
Track possible side effects and their impact
Record nausea, vomiting, diarrhoea, appetite loss, disturbed sleep, dizziness, fatigue, and muscle cramps. For each symptom, note the time, severity, duration, and effect on eating, sleeping, walking, or normal activities. Track weight when a reading is available.
Note appetite changes and vomiting alongside it, since those details give a weight change useful context. MedlinePlus lists these digestive, sleep, energy, muscle, and weight-related problems among established donepezil adverse effects in its drug information. A compact entry might read: "September 9, 8 p.m.—5 mg taken; nausea began at 9 p.m.; mild; lasted 40 minutes; ate half of dinner." This is more useful than writing only "felt unwell.".
Include pulse, fainting, and falls
When a pulse reading is available, record the number, date, time, and whether the person felt dizzy, weak, faint, or had chest pain. Also document every fainting episode or fall, including what happened immediately beforehand. Guidance for acetylcholinesterase inhibitors, the medicine group that includes donepezil, recommends clinician-led pulse monitoring monthly after starting or changing treatment and every six months once treatment is stable.
Periodic body-weight monitoring is also considered by the NHS Specialist Pharmacy Service. Do not use a diary entry as a substitute for assessment. Fainting accompanied by a slow pulse or chest pain needs immediate medical attention.
Know what cannot wait for the next review
Flag serious symptoms in the diary, but seek immediate medical assessment rather than waiting for the scheduled appointment. Warning signs include: These digestive signs may indicate gastrointestinal bleeding, particularly when there is an ulcer history or use of nonsteroidal anti-inflammatory drugs, often called NSAIDs.
MedlinePlus advises prompt care for these and other serious symptoms in its donepezil safety information. For urgent events, record when the symptom began, what was observed, the latest donepezil dose, and any other medicines taken. Bring the diary or a photograph of the relevant page to the medical assessment.
- A seizure.
- Fainting with a slow pulse or chest pain.
- New breathing problems.
- Stomach pain with black or tarry stools.
- Red blood in the stool.
Prepare a useful review summary
Before the medication review, identify patterns without trying to diagnose their cause. Mark repeated symptoms, changes after starting or increasing the dose, missed-dose dates, falls, and specific gains or losses in everyday function. Bring the full diary plus a one-page summary containing: A diary can show timing and patterns, but it cannot establish whether deterioration came from donepezil or from the underlying dementia.
- Current dose and usual time taken.
- Start date and dose-change dates.
- Missed doses.
- New or stopped medicines and supplements.
- Most frequent symptoms and their timing.
