How Does Vigamox Work?

Vigamox belongs to a class of antibiotics known as fluoroquinolones, also known as "quinolones." These medications work by interfering with two important bacterial enzymes: topoisomerase IV and DNA gyrase. These enzymes are necessary for bacteria to be able to copy and repair DNA, which are important steps required in order for bacteria to multiply.

When and How to Take This Medicine

General considerations to keep in mind when using Vigamox include the following:
  • This medication comes in the form of an eye drop. It is usually used in the affected eye(s) three times daily for seven days.
  • In order to prevent contamination of the drops, do not touch the tip of the dropper to any surface, including the surface of the eye.
  • You should not wear contact lenses while using this medication, since you should not wear contacts while you have an eye infection.
