What should I know about Cortisporin ointment before using it?


There are certain precautions you should be aware of before using Cortisporin ointment. It may cause harmful reactions with certain medical conditions, including:

  • viral or fungal infections
  • diabetes
  • tuberculosis
  • immune disorders
  • heart or kidney disease
  • eye diseases like glaucoma and cataracts

Tell your doctor if you have recently received a vaccine or had a tuberculosis test come back positive. Similarly, Cortisporin ointment may interact poorly with other medications, especially chemotherapy treatments. If you are pregnant or breastfeeding, you should alert your doctor, as Cortisporin ointment may harm a fetus or a nursing infant. Also, be aware that Cortisporin ointment may cause serious side effects, ranging from rashes and allergic reactions to hearing and kidney problems. Keep in mind that Cortisporin ointment works only on bacterial infections, not viral or fungal infections. It also is not for use in the eyes or on the ear, if you have a hole in your eardrum. Finally, you should not bandage or wrap the area after applying the ointment, unless ordered by a doctor.
