Who Makes This Medication?

How Does Quixin Work?

Quixin works by killing bacteria that cause eye infections. It does this by interfering with a bacterial enzyme called DNA gyrase. This enzyme is needed by the bacteria to make DNA, which is important for the bacteria to multiply. Quixin does not kill viruses.

When and How to Use It

Some general considerations for using this medicine include the following:
  • Quixin comes in the form of an eye drop. It is normally dosed several times a day. Make sure you know your individual instructions for using this medicine.
  • Many eye infections can spread easily. To prevent further spread of infection, try not to touch your eye while using this medicine, wash your hands thoroughly before and after use, and avoid touching the tip of the dropper to any surface, including your eye or hands.
  • You should not wear contact lenses while you are using this medicine. Ask your healthcare provider when you may use contacts again.
  • This medication should only be used in the eye. Do not take it by mouth or apply it to your skin.
  • Make sure to dispose of this medication after you finish treatment. Do not save it for later use.
  • You should begin to feel better within a few days of starting treatment. However, this does not mean your infection is gone. It is important that you finish your full Quixin course. If you stop using this medicine too soon, your infection may not be cured, and antibiotic resistance may develop.
  • For the medication to work properly, it must be used as prescribed.
