Why is injection a problem for a magic healing elixer? Not one person with a severed tendon would ever say "I'd love some help knitting this baby back together so I can walk again, but injections, that's just not going to happen"
One is the injectable self-administration is difficult and the cost of a daily outpatient visit would be exorbitant, even with NPs doing administration. Plus in both cases compliance might not be adequate.
Compliance might not be adequate? How do you figure? Injuries to muscle, tendon, and ligament are extremely debilitating and don't normally heal well. I struggle to imagine someone who can't be bothered.
I used to work in pharma and you’d be shocked by the adherence statistics. Even just taking a tablet is difficult for most people, and a shocking number of refillable prescriptions are never refilled.
With injections it’s far worse, even when people know that it will be life saving.
