Answer by vv
It’s hard to put a figure on this.
I should think that about 90% of prescriptions are filled when originally written and that (absent a financial problem) about 75% of those religiously follow directions as written and take all their medications.
There is an outfit on the West Coast that keeps these stats; IMS.
