Why the same NAC (N-Acetyl Cysteine) costs $11 at one pharmacy and $15 at another
It's the same FDA-approved N-Acetyl-L-Cysteine from the same wholesalers, sitting on different pharmacy shelves with vastly different markups. The price spread on NAC (N-Acetyl Cysteine) between the cheapest and most expensive pharmacy in a typical US city is ~$6 per month — that's $72/year for the exact same medication.
Three drivers cause the spread: (1) chain pharmacies use opaque national list prices, (2) independents compete on cash-pay because they have to, and (3) PBM contracts at chains inflate cash prices to protect rebate economics. None of this benefits you. Bidding does.
