@lsittll, a friend of mine asked this question on her blog back in 2015 here:
- Hack needed: Tiny pills, trembling hands https://susannahfox.com/2015/04/19/hack-needed-tiny-pills-trembling-hands/
I wonder if this response by someone named Lori might help
"She can’t hold the small pills and has a hard time with the bottles and lids. I ordered some salt and pepper shakers that have a rotating dispenser, small holes for seasoning BUT also has a wider one that will work for different sizes of pills. I plan to put a label on them for her (either a reusable label or with a sharpie and painter’s tape.) The lids are easy to remove to refill. I got two different types for her to try: https://www.amazon.com/dp/B07WFCFMD2?ref=ppx_pop_dt_b_asin_title&th=1 "

Please report back if you find a solution that works for you.
