What it is
TRINATAL RX 1 TABLET is how the CMS NADAC file names this product. The FDA NDC Directory does not list its NDC as a package of its own, so OpenBill has no FDA names, dosage form or pharmacologic class for it.
The NADAC file of 2026-10-14 prices it under one NDC (National Drug Code), 13811-0007-10.
NADAC classes it as a generic drug (rate-setting class G), and does not mark it as sold over the counter.
What pharmacies pay
Pharmacies pay $5.83 for 30 tablets (30 × $0.19426 per EA, rounded to the cent), by the CMS NADAC file of 2026-10-14; that price took effect on 2026-09-23. That is what pharmacies pay their suppliers, not what they charge you.
NADAC’s explanation code for it: 1, calculated from the most recently completed pharmacy survey.

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 30 tablets? 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.
