<human>: Give me a shortened version of the text

Sorry if this is annoying, but I'm writing a short story where pills are a very important part.  This isn't what the story's about, but basically an old man left alone can't open the child-proof bottles and knows it will kill him.

I've been reading medicine sites for the past couple hours, but I'm not really seeing what I need:  An accurate collection of pills that an elderly person would take (arthritis medication, maybe blood pressure, etc.)  And the absence of these pills would likely be deadly.

I really just need one person to tell me a collection of pills that would make sense.  I'd call my nurse friend, but I feel silly bothering people about a short story.
<bot>: Can you tell me a collection of pills an old person would take every day, where not having them anymore could potentially kill them?
