Gatifloxacin Overdose

The effects of a gatifloxacin overdose are unknown at this time because there are no reported cases of people using too much. Based on reports of other fluoroquinolone overdoses, however, symptoms might include severe eye irritation and discomfort, or nausea, vomiting, and headaches if the eye drop was accidentally taken by mouth. Treatment would involve relieving any symptoms that occurred as a result.

Can You Use Too Much Gatifloxacin?

Gatifloxacin (Zymar®, Zymaxid™) is an antibiotic that belongs to the fluoroquinolone class of medications. It comes as an eye drop and is used to treat bacterial conjunctivitis (commonly called pink eye). As with most medications, it is possible to overdose on gatifloxacin.
The specific effects of an overdose will likely vary, depending on a number of factors, including the gatifloxacin dosage and whether it was applied to the eye or taken by mouth.

Effects of a Gatifloxacin Overdose

To date, there have been no reported cases of an overdose with this medication. Using too much gatifloxacin in the eye may cause eye irritation or discomfort.
Taking a gatifloxacin overdose by mouth could cause effects similar to an oral overdose with other fluoroquinolones. These may include:
  • Headache
  • Dizziness
  • Drowsiness
  • Disorientation
  • Slurred speech
  • Tremors
  • Nausea and vomiting
  • Diarrhea
  • Stomach pain
  • Heart rhythm problems
  • Kidney problems.
However, these problems are not likely, as the amount of gatifloxacin in an entire bottle is quite small.

Treatment Options

An overdose of gatifloxacin in the eyes may be flushed out with warm water. Other treatment, if necessary, would likely involve supportive care, which consists of monitoring and treating any symptoms that occur as a result of the overdose.
It is important that you seek immediate medical attention if you believe that you or someone else may have used too much gatifloxacin.
