Gatifloxacin is a prescription antibiotic used to treat certain kinds of eye infections. It comes in the form of an eye drop that is usually applied to the affected eye two to eight times a day for seven days. Most people have no problems when using it; however, side effects are possible, such as increased tearing, eye redness, and eye irritation.

What Is Gatifloxacin?

Gatifloxacin is an antibiotic in a class of medications called fluoroquinolones, or "quinolones" for short. It comes as an ophthalmic solution (eye drop), sold under the names Zymaxid™ and Zymar®.
Gatifloxacin used to be available in tablet, oral suspension, and intravenous (IV) injectable forms under the brand name Tequin®; however, Tequin was withdrawn from the United States market because of concerns about serious side effects.

Are There Side Effects?

Just like any medicine, gatifloxacin can cause side effects. However, not everyone who uses the medication will experience problems. In fact, most people tolerate it quite well.
If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious reactions are less common.
Commonly reported gatifloxacin side effects may include but are not limited to:
  • Eye irritation, pain, redness, or itching
  • Eye discharge
  • Increased tearing
  • Blurred vision
  • Feeling like something is in the eye
  • Swelling around the eye
  • An unpleasant taste
  • Worsening of conjunctivitis.
