Elderly parents and emergency medication

[NewToRenting]

My nearly 80 year old parents live alone (not in UK) and have various health issues. Last week my dad had heart pain and they could not find any sorbitrate (I think it prevents a heart attack if taken in time) in the house. Luckily a neighbour managed to find one.
So here's the question, where would you store such life-saving time-critical medication in your house? My mom is stage 4 cancer and occasionally suffers from brain fog, so it has to be a really obvious place.
I am thinking of buying them a key fob that stores pills, and attaching that to their car key, so it's always with them, in or out of the house. But I want to create a few more emergency store points in the house, so even in panic they can lay their hands on one. As with most of us, they have stuff everywhere, every drawer and cupboard is full to bursting, so just keeping it in the medicine drawer wont be a good solution.

Any suggestions please?

A wall mounted first aid box (they are bright green and white) on the kitchen wall?

Great idea, thank you

Or the fridge. Check with pharmacist first. It’s often where people are recommended to put community DNACPR forms as then paramedics can find easily.

Agree with fridge if pharmacist says that's OK. You used to be able to get a sticker saying 'medication in fridge'

First aid box in the fridge ? You could put a note on the fridge door saying what to do in an emergency , takes all the decision making out of the incident .
