Can anyone recommend a small medication safe box that will fit in a drawer and be unobtrusive. It’s for a carer to use to give my dad his Alzheimer’s medication. I don’t want it to be too big and obtrusive or he and my mum will spend their time worrying about it. If it can be tucked out of the way, though they hopefully won’t. Thank you. Needs the be the right size for blister pack.
