Can you cut 10mg aricept in half for half dose?

Yes, you can cut a 10 mg tablet of Aricept (donepezil) in half to achieve a 5 mg dose, as long as the tablet is not extended-release or formulated in a way that makes it unsuitable for splitting. However, it's important to consult with a healthcare provider or pharmacist before doing so to ensure it's appropriate for your specific situation and to confirm the tablet can be safely split. Always follow your healthcare provider's guidance regarding medication adjustments.
