Eyes Home > Zymar Warnings and Precautions

You should avoid Zymar if you are allergic to fluoroquinolone antibiotics. If your healthcare provider has prescribed this medicine for your pink eye infection, it's important to wash your hands frequently and avoid touching the tip of the container to any surfaces. Being aware of these and other precautions and warnings can help ensure a safe treatment process with Zymar.

What Should I Tell My Healthcare Provider?

You should talk with your healthcare provider prior to using Zymar® (gatifloxacin) if you have any allergies, including to medications, foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
  • Pregnant or thinking of becoming pregnant
  • Breastfeeding.
In addition, tell your healthcare provider about any other medications you are taking, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Specific Precautions and Warnings With Zymar

Some warnings and precautions to be aware of with this drug include the following:
  • Zymar is a topical eye medication. It is made for use in the eyes.
  • This product does not kill all types of organisms that may cause eye infections. In rare cases, using this medication for a long time may cause an overgrowth of these nonsusceptible organisms, including fungi. If your infection seems to get worse or has not improved within a week, talk to your healthcare provider. You may need a different medication.
  • Although some temporary eye irritation may occur with Zymar use, let your healthcare provider know if you experience extreme or persistent eye irritation.
  • You should not wear contact lenses while you have bacterial conjunctivitis or while using Zymar. The use of contact lenses may worsen your infection.
  • It is very important that you not touch the tip of the Zymar container to your eye, fingers, or other surfaces to keep it clean and free from germs. Bacterial eye infections, such as conjunctivitis, spread easily, so make sure you wash your hands often while using this medicine, especially after you touch your eyes.
  • Some people may experience a severe allergic reaction from fluoroquinolones such as Zymar, even after just one dose. Stop using this medication and seek immediate medical attention if you develop any signs of an allergic reaction, including:
    • Rash or hives
    • Itching
    • Swelling of the lips, tongue, or face
    • Throat tightness
    • A rapid heartbeat
    • Wheezing
    • Difficulty breathing.
  • Zymar is unlikely to react with other medications (see Zymar Drug Interactions).
  • Zymar is a pregnancy Category C medication, which means that it may not be safe for use during pregnancy, although the full risks are currently unknown (see Zymar and Pregnancy for more information).
  • It is unknown if Zymar passes through breast milk. Therefore, if you are breastfeeding or plan to start, check with your healthcare provider before using this drug (see Zymar and Breastfeeding).
