Donepezil, while helpful for managing Alzheimer’s symptoms, can cause side effects. These vary in severity and frequency.
Gastrointestinal Issues
Nausea, diarrhea, and vomiting are common. These usually improve with continued use or a lower dose. Consider reporting these symptoms to your doctor, particularly if they are severe or persistent.
Neurological Effects
Some patients experience dizziness, headache, or insomnia. Slowing down the dosage increase, if applicable, or adjusting medication timing might help manage these effects. Severe dizziness warrants immediate medical attention.
Other Potential Side Effects
Less frequent side effects include muscle cramps, fatigue, and syncope (fainting). Bradycardia (slow heart rate) is also possible and requires careful monitoring, especially in individuals with pre-existing heart conditions.
Serious Risks and Precautions
While rare, serious reactions can occur. These include severe allergic reactions (anaphylaxis), liver problems, and seizures. Seek immediate medical help if you experience any of these.

Interactions and Contraindications
Donepezil can interact with other medications. Always inform your doctor about all medications, supplements, and herbal remedies you are taking. Certain conditions, such as severe liver or heart disease, might make Donepezil unsuitable.
