Cortisporin ointment overdose; Baciferm overdose
Bacitracin zinc is very safe. However getting bacitracin zinc in your eyes may cause redness and some pain and itching.
Intentionally eating bacitracin in large amounts may cause you to have some pain in your stomach and possibly throw up.
Rarely bacitracin zinc may cause an allergic reaction. You are most likely to have some redness and itching of your skin. However, like any substance, a severe allergic reaction (anaphylaxis) can occur.
