Does dementia medication have any side effects?

Same as a lot of medication in that if you read the leaflet, it lists all the possible side effects like upset tummy etc but I haven't had any so far. I do feel tired a lot but that is probably my dementia.

I'm on Donepezil and I read it can make you feel sick or give you headaches, but to be honest I get headaches anyway. Always have. Don't feel any different.

Some of it can make you drowsy or sick but everyone's different. Hasn't bothered me yet. I'd rather take it than not take it!
