Is there a generic for lansoprazole (Prevacid)?

The FDA approved the first generic lansoprazole on November 10, 2009. 30 generic applications are approved; 20 of them carry a current (not discontinued) marketing status in Drugs@FDA; that status is not evidence that the generic is on sale.

FDA's NDC Directory lists lansoprazole from 59 labelers under a generic (ANDA) application and from 8 brand labelers. A listing means the company has registered the product for sale; it does not show that every pharmacy stocks it.

The Orange Book lists no patent for Prevacid tablets; a patent listed only for Lansoprazole tablets runs to April 21, 2036. A patent or exclusivity date is not the date a generic goes on sale: court cases and settlements move it either way.

What do pharmacies pay for lansoprazole (Prevacid)?

In CMS's NADAC survey of October 7, 2026, pharmacies paid $0.106 per Lansoprazole DR 30 mg capsule, about the same as a year earlier. Prices per unit in the table differ many-fold by strength, form and brand, so compare like with like. The chart's scale runs from the lowest to the highest price shown, not from zero. NADAC is what retail pharmacies paid their wholesalers, per unit, in CMS's monthly survey; what a patient pays depends on insurance and the pharmacy.
