The demand for pill bottles literally does grow before anyone takes the medication, no?
And correct I agree they wouldn't designate the demand for pill bottles as the first order effect. That's because despite happening first, it's not the most important object of analysis. That's why it's a disproof of your earlier claim that second order effects aren't more significant than first order ones: because if they were, they'd be considered the first order effect.

Only really in the US. In most other countries they use blister packs instead. Global consumption of blister packs is so huge (not just for prescription medications, also OTC, vitamins, supplements, and complementary medicines), even a blockbuster medication likely only makes a modest difference to manufacturer demand in percentage terms.
