What it is

FDA lists 8 labelers (the companies named on the label) for its NDCs, among them Mylan Pharmaceuticals Inc., Major Pharmaceuticals and Camber Pharmaceuticals, Inc.

The NADAC file of 2026-10-14 prices it under 12 NDCs (National Drug Codes); the FDA directory lists 9 of them.

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