I’ve been carrying around multiple little baggies of pills in my backpack for years and over 20+ flights, several international, they’ve never asked.

Some are separated but loose in the bag (ibuprofen, cetirizine, diphenhydramine, from a bottle), and some were trimmed to minimum size from a blister pack and placed in the bag.

They focus a lot more closely on my headphones, charging cables, battery packs, etc.

So whatever is most convenient for you, in my opinion.
