CHLORPROMAZINE 100 MG TABLET

What it is

CHLORPROMAZINE 100 MG TABLET is how the CMS NADAC file names this product. The FDA NDC Directory lists it as “chlorpromazine hydrochloride” and “chlorpromazine”, as its NDCs’ listings variously write the nonproprietary name.

FDA gives its dosage form as “tablet, coated”, “tablet, film coated”, “tablet, sugar coated” and “tablet” and its route as oral.

FDA lists 11 labelers (the companies named on the label) for its NDCs, among them Lannett Company, Inc., Upsher-Smith Laboratories, LLC and Northstar Rx LLC.

FDA’s Established Pharmacologic Class for it is Phenothiazine.

The NADAC file of 2026-10-14 prices it under 19 NDCs (National Drug Codes); the FDA directory lists 14 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 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.
