Price survey date
* Supply estimates are based on NADAC acquisition cost only (30 or 90 tablets/capsules). Your actual pharmacy cost will be higher due to dispensing fees and markup.
The price shown is NADAC (National Average Drug Acquisition Cost) — what pharmacies across the US actually pay their suppliers for this drug, surveyed weekly by CMS/Medicaid. Think of it as the wholesale floor price. Your out-of-pocket cost at the pharmacy will be higher, since pharmacies add a dispensing fee (typically $3–$12) and a markup to cover their overhead.
Unlike hospital prices — which are now legally required to be published — drug prices negotiated between insurers and pharmacies are trade secrets. Pharmacy Benefit Managers (PBMs) like CVS Caremark, Express Scripts, and OptumRx negotiate confidential rates on behalf of insurers. What your plan pays, and what your copay will be, depends on:
To find your specific cost: check your plan's drug formulary online, call the number on your insurance card, or ask your pharmacist to run it through your insurance before you pick up.
Compare to your copay
If your insurance copay is close to or below the NADAC price, you may actually save money paying cash — especially for cheap generics.
Ask about generics
Brand drugs can cost 80–99% more than their generic equivalent for the same active ingredient. Ask your doctor if a generic is appropriate.
Try discount programs
GoodRx, RxSaver, and similar services negotiate cash prices that are often below insurance copays. Always worth checking before you pay.
Consider cost-plus pharmacies
Mark Cuban's Cost Plus Drugs (costplusdrugs.com) charges NADAC + 15% markup + dispensing fee — one of the most transparent pricing models available.
Not medical or financial advice
Never change your medication based solely on price data. Always consult your doctor or pharmacist before switching drugs, requesting generics, or changing your dosage. NADAC prices are national averages and may not reflect what your specific pharmacy pays or charges.
