Shadowfoot:
When I had a broken arm in the US I signed a document to not have a childproof top on the prescribed drugs. This was because I couldn’t open it. I know I painfully signed it with my broken arm but in hindsight I could have just scribbled with my other hand.
By signing the document it meant the drug company absolved responsibility for any kids opening the bottle.
Personally, I'd be more worried about the kid than the pharma company.
On a more practical note, a friend of mine with serious health issues has a medicine container, which he fills once a week. His wife helps him put the right pills in the right numbers for the right days in it on a Sunday night, and the container has a key lock he can open, but no chance a kid can open it.
Perhaps if you felt that might help, you could have a look into that @mikeb4
