LACTULOSE 10 GM/15 ML SOLUTION

What it is

LACTULOSE 10 GM/15 ML SOLUTION is how the CMS NADAC file names this product. The FDA NDC Directory lists it as “lactulose” and “lactulose solution usp, 10 g/15 ml”, as its NDCs’ listings variously write the nonproprietary name, under the trade name “Lactulose Solution”.

FDA gives its dosage form as solution and its route as “oral” and “oral; rectal”.

FDA lists 8 labelers (the companies named on the label) for its NDCs, among them Xttrium Laboratories, Inc., PAI Holdings, LLC dba PAI Pharma and Lannett Company, Inc.

FDA’s Established Pharmacologic Class for it is Osmotic Laxative.

The NADAC file of 2026-10-14 prices it under 19 NDCs (National Drug Codes); the FDA directory lists 18 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 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 $0.0125 to $0.02237 per ML for this product, depending on the NDC.
• How much is in the package I am getting? This page uses 1 mL; your package may hold a different amount.
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
