How long is pink eye contagious after starting antibiotic?

Viral or bacterial?: If your pink eye issue to a bacterial infection, you should no longer be considered contagious after 24-48 hours after starting the antibiotic drops. If, however, your pink eye is due to viral infection, you are likely to be contagious for as long as you are having symptoms.

During symptoms: Because pink eye is usually viral and not bacterial antibiotics actually will do nothing to help with the pink eye. For that reason you are contagious the entire time you are symptomatic regardless of if you are taking antibiotics or not.
