EPRONTIA 25 MG/ML SOLUTION

What it is

EPRONTIA 25 MG/ML SOLUTION is how the CMS NADAC file names this product. The FDA NDC Directory lists it as topiramate, under the trade name “Eprontia”.

FDA gives its dosage form as solution and its route as oral.

The labeler, the company named on the label, is Azurity Pharmaceuticals, Inc.

FDA lists no Established Pharmacologic Class for it.

The NADAC file of 2026-10-14 prices it under 3 NDCs (National Drug Codes).

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

What pharmacies pay

Pharmacies pay $1.58 – $2.72 for 1 mL, depending on the NDC ($1.58252 to $2.7158 per ML), by the CMS NADAC file of 2026-10-14; those prices took effect between 2026-01-01 and 2026-09-23. That is what pharmacies pay their suppliers, not what they charge you.

NADAC’s explanation codes for it: 1, calculated from the most recently completed pharmacy survey; 4, carried forward from the previous file; 5, calculated based on package size.

The NADAC of 1 of these 3 NDCs was carried forward from an earlier file (NADAC explanation code 2 or 4), not newly surveyed: it took effect on 2026-01-01. The file is new; the price is not.

NADAC also lists, on the row of its brand NDCs, what pharmacies pay for the generic equivalent, a different product: $1.08239 to $2.08667 per ML filed.

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 mL? Is it lower than what I would pay through my insurance?
• Which NDC (the 11-digit number on the package) is this? Pharmacies pay $1.58252 to $2.7158 per ML for this product, depending on the NDC.
• Is a generic version available, and would it suit me? NADAC lists a generic with the same ingredient, strength and dosage form by FDA: TOPIRAMATE 25 MG/ML SOLUTION. Ask your pharmacist or prescriber; do not switch on your own.
• How much is in the package I am getting? This page uses 1 mL; your package may hold a different amount.
• 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.
