How much cheaper is generic OxyContin than brand-name?
Generic oxycodone extended-release (the active ingredient in OxyContin) costs 70-90% less than brand-name OxyContin. A 30-day supply of brand-name OxyContin (60 mg) averages $400-$600 without insurance, while generics run $50-$150 for the same strength and quantity. Prices vary by pharmacy, dosage, and insurance; cash prices at chains like Walmart or Costco can drop generics below $100.[1][2]
What drives the price gap?
Purdue Pharma lost exclusivity on OxyContin in 2010 after reformulation patents expired, allowing generics from Teva, Mallinckrodt, and others. Brands maintain higher prices due to marketing, branded packaging, and residual patent protections on specific formulations (e.g., abuse-deterrent tech). Generics face less R&D recovery burden.[3][4]

| Average cash price | $450 | $90 |
| With commercial insurance | $20-$50 copay | $10-$30 copay |

When did generics first hit the market?
FDA approved the first generic OxyContin in 2010 for immediate-release oxycodone, but extended-release versions followed in 2015 after settling patent disputes with Purdue. Full generic entry expanded competition, slashing prices by over 80% within years.[4][6]
Does insurance coverage differ?
Most plans favor generics with lower copays or mandatory substitution. Brand OxyContin requires prior authorization in many cases, and Medicare often excludes it from lowest tiers. Uninsured patients save most switching to generics.[1][7]
Are there quality or effectiveness differences?
Generics must match brand bioequivalence (80-125% absorption rate per FDA). Patients report no major differences in pain control, though some note slight variations in pill feel or side effects from inactive ingredients. Abuse-deterrent generics mimic the brand's crush-resistant formula.[8]
Where to check current prices and patents?
Use GoodRx or Drugs.com for real-time quotes by ZIP code. OxyContin's key patents expired by 2021, with no major barriers to generics; check DrugPatentWatch.com for updates on remaining formulation patents.[9][10]
