Pharmacist tips for Erythromycin eye ointment

pharmacist

General tips

  • Use erythromycin eye ointment exactly as prescribed. Don't stop using it before you finish treatment, even if your symptoms improve. Stopping too early can cause your infection to come back or become harder to treat.
  • Don't let the tip of the erythromycin eye ointment tube touch your eye, eyelid, fingers, or other surfaces. This can spread germs into the ointment and cause serious harm to the eye.
  • Don't wear contact lenses while using erythromycin eye ointment. The ointment can coat your lenses and cause blurry vision, and wearing contacts during an eye infection can make irritation worse. Ask your care team when it's safe to wear contacts again.
  • Erythromycin eye ointment can temporarily cause blurry vision after you apply it. Avoid driving or using machinery until you can see clearly again.
  • Don't share your erythromycin eye ointment tube with anyone else. Sharing eye medications can spread infections.
  • Pregnancy and breastfeeding: There isn't enough information to know whether erythromycin eye ointment is safe during pregnancy or breastfeeding. Talk to your prescriber if you're pregnant, planning to become pregnant, or breastfeeding.
  • Storage: Keep erythromycin eye ointment at room temperature, away from excessive heat. Keep the cap tightly closed when you're not using it.

How to apply erythromycin eye ointment

  • Follow your prescriber's instructions before applying the ointment for yourself or for your child.
  • Prepare: Wash your hands with soap and water before applying. Tilt your head back slightly and gently pull down your lower eyelid to make a small pocket.
  • Apply: Hold the tube above your eye and squeeze a thin strip of ointment into the pocket as directed. Avoid touching the tube tip to your eye or surrounding skin.
  • After applying: Gently close your eye for 1 to 2 minutes to help spread the medication. Wipe away any extra ointment with a clean tissue and wash your hands again.
