FENTANYL 12 MCG/HR PATCH

What it is

FENTANYL 12 MCG/HR PATCH is how the CMS NADAC file names this product. The FDA NDC Directory lists it as “fentanyl” and “fentanyl transdermal”, as its NDCs’ listings variously write the nonproprietary name, under the trade name “Fentanyl system”.

FDA gives its dosage form as “patch” and “patch, extended release” and its route as transdermal.

FDA lists 4 labelers (the companies named on the label) for its NDCs, among them Mylan Pharmaceuticals Inc., SpecGx LLC and ALVOGEN.

FDA’s Established Pharmacologic Class for it is Opioid Agonist.

The NADAC file of 2026-10-14 prices it under 7 NDCs (National Drug Codes); the FDA directory lists 4 of them.

NADAC classes it as a generic drug (rate-setting class G), and does not mark it as sold over the counter.

What to ask at the counter

None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.

• What is your cash price for 1 patch? Is it lower than what I would pay through my insurance?
• If you have Medicare Part D: what is my plan’s copay or coinsurance for it? The Part D average on this page is not what you pay.
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
