Who Makes Floxin?

Brand-name Floxin was made by Ortho-McNeil Pharmaceutical, Inc. However, this medication is no longer available as Floxin, although generic versions are available. Generic Floxin is made by various manufacturers, including Teva Pharmaceuticals, Ranbaxy Pharmaceuticals, Inc., and Dr. Reddy's Labs, Ltd.

How Does It Work?

Floxin works by killing certain bacteria that cause infections. It does this by interfering with two bacterial enzymes called topoisomerase four (IV) and DNA gyrase. These enzymes are required for bacteria to copy and repair DNA, which are important steps for bacteria to multiply.
