ZDoggMD on Prescription Drug Costs: Why Americans Pay 3× What Canadians Pay

Americans pay the highest prescription drug prices in the world — typically 2–4 times what comparable countries pay for identical medications. ZDoggMD has examined why, and the answer involves pharmaceutical pricing opacity, the pharmacy benefit manager (PBM) system, and policy choices that have historically protected pharmaceutical industry revenue at patient expense.

The PBM System Nobody Understands

Pharmacy benefit managers — the middlemen between pharmaceutical manufacturers, insurers, and pharmacies — negotiate drug prices and formulary placement. They receive rebates from pharmaceutical manufacturers in exchange for favorable formulary placement. The rebate system creates perverse incentives: PBMs benefit from high list prices (because rebates are a percentage of list price), which is the opposite of what patients need.

ZDoggMD has used insulin pricing as the clearest illustration: three manufacturers produce the vast majority of US insulin. List prices for insulin increased over 300% between 2002 and 2013, while manufacturing costs remained essentially flat. The price increases were enabled by the PBM rebate system, which rewarded higher list prices with better formulary placement. Patients who rationed insulin and died were the real-world consequence of an opaque pricing system optimized for PBM and manufacturer revenue.

The Physician's Role

Physicians are often the first to discover that a prescribed medication is unaffordable — when the patient doesn't refill it, or reports rationing, or calls asking for a cheaper alternative. Checking drug costs before prescribing, using GoodRx or similar tools, prescribing 90-day supplies, using generic alternatives — these are practical steps that help individual patients while the structural problem waits for policy solutions.
