Donepezil: What You Need to Know

When working with Donepezil, an acetylcholinesterase inhibitor used to manage symptoms of Alzheimer’s disease. Also known as Aricept, it helps improve cognition, mental processes like memory and thinking in people with Alzheimer’s disease, a progressive neuro‑degenerative disorder affecting memory, judgment and daily function. Understanding how acetylcholinesterase inhibitor, a drug class that blocks the enzyme breaking down acetylcholine works is key to using Donepezil safely and effectively.

How Donepezil Improves Brain Function

Donepezil’s main job is to inhibit acetylcholinesterase, the enzyme that destroys acetylcholine, a neurotransmitter crucial for learning and memory. By keeping acetylcholine levels higher, the drug supports neuronal communication, which can slow the decline in cognition seen in Alzheimer’s disease. The result isn’t a cure, but many patients notice steadier memory recall and better attention during daily activities.

Doctors usually start patients at a low dose, often 5 mg once daily, then increase to 10 mg after four to six weeks if tolerated. Some clinicians may consider a 23 mg dose for those who have been stable on 10 mg for three months and need extra support. The timing of the dose matters; taking Donepezil in the evening can reduce daytime stomach upset, but some people prefer morning dosing to avoid night‑time vivid dreams.

Side effects are common but usually mild. The most frequent are nausea, diarrhea, insomnia, and muscle cramps. A small percentage experience serious heart rhythm changes, so regular ECG checks are advised for patients with existing cardiac issues. Liver function tests are also recommended because Donepezil is metabolized in the liver.

Drug interactions can alter Donepezil’s effectiveness. Strong CYP2D6 inhibitors like fluoxetine or paroxetine raise Donepezil levels, increasing the chance of side effects. Anticholinergic medications—such as certain antihistamines or bladder drugs—counteract its benefits by blocking acetylcholine, so doctors often advise avoiding them if possible.

Practical tips can make therapy smoother. Swallow the tablet with a full glass of water, and don’t crush it unless a liquid formulation is prescribed. If you miss a dose, take it as soon as you remember unless it’s close to the next scheduled dose; then skip the missed one and continue as normal. Keeping a medication schedule—using a pill organizer or phone reminder—helps maintain steady blood levels, which is essential for consistent symptom control.
