I had a prescription for 1 20mg pill a day. Pharmacy didn't have 20mg but they had 10mg. They couldn't give me 2 10s instead of 1 20 because regulations didn't allow that. Yeah, we need less regulations.

There is likely no regulation that says this. Doctors and pharmacists have very broad legal authority to prescribe whatever they see fit.

It’s almost assuredly an insurance/PBM billing issue, not a regulatory thing.
