Donepezil is given for mild, moderate, and severe AD, and dosing may be increased, although it must be titrated up slowly. For patients with moderate to severe AD who have taken 10 mg once daily for at least 3 months, the dose can be increased to 23 mg once daily. Donepezil is not given twice daily. Donepezil does not cause hepatotoxicity; hepatotoxicity occurs with tacrine, the first acetylcholinesterase (AChE) inhibitor, which now is rarely used. Dosing is increased after 3 months, not 1 year.
