Summary
Corticosteroids can weakly induce CYP3A4, which could modestly lower donepezil exposure. Any loss of efficacy would be small and is rarely recognised clinically.
What this interaction means in plain words
Cortisone and Memantine-donepezil have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Weak glucocorticoid-mediated CYP3A4 induction may increase donepezil clearance.
