Why Is Ferrous Sulfate So Expensive?(And How to Pay $3 Instead)
Ferrous Sulfate averages $12/month at US retail. Through Script Unlock pharmacy bidding, the same prescription typically costs $3/month. Here's exactly why retail is so high — and how to stop paying it.
5 Real Reasons Ferrous Sulfate Costs So Much
Limited Generic Manufacturers
Generic Ferrous Sulfate is technically off-patent, but only a handful of manufacturers produce it in the US. Concentrated supply lets manufacturers and chains keep prices elevated. The active ingredient costs cents to produce — the price you see reflects market concentration, not manufacturing cost.
PBM Spread Pricing
Pharmacy benefit managers (PBMs) sit between insurance plans and pharmacies. PBMs charge plans a higher price and pay pharmacies less — pocketing the spread. For high-volume drugs like Ferrous Sulfate, this spread can be substantial. You see it as your copay; the PBM books it as profit.
Manufacturer Pricing Power
Ferrous Sulfate's manufacturer sets the wholesale acquisition cost (WAC) — the "list price" — independent of production costs. US drug prices are not regulated at the federal level. WAC for Ferrous Sulfate has risen above the general inflation rate for the past decade, driving up both copays and uninsured cash prices.
Insurance Tier System
Insurance formularies place Ferrous Sulfate on a tier. Higher tiers mean higher copays — and tier placement depends partly on rebate deals between PBMs and the manufacturer, not on clinical evidence. If your plan assigns Ferrous Sulfate to tier 3 or higher, you absorb the cost of that negotiation.
Pharmacy Margin Variance
Pharmacies set their own cash prices for Ferrous Sulfate. National chains target 30–40% margins using insurance reimbursement formulas even for cash patients. Independents often accept lower margins to win volume. Same Ferrous Sulfate script — $3 at one pharmacy, $12 at another, two miles apart.

Between the factory and your medicine cabinet, 5 parties each take a margin on every $12 you pay.
Script Unlock removes the PBM from the chain and lets pharmacies compete directly — collapsing the markup stack.

“I was paying $12/month until I found pharmacy bidding”
“I’d been filling Ferrous Sulfate at the same chain for two years — $12 every month without question. I assumed that was just what it cost. My insurance covered some of it, but not enough. Then I uploaded the prescription to Script Unlock. Within five minutes I had four bids: $3, $$7, $$12, and $$8. The cheapest was an independent pharmacy I’d driven past a hundred times. I switched. I’m saving $9/month — $108/year. Same medication. Same dose. Same generic. The only thing different is someone competing for my prescription instead of assuming I’d just keep paying.”
