Polysporin is the brand name for Polymyxin B sulfate gramicidin eye drops which is a sterile, anti-microbial agent that is used to treat superficial infections of the eye that are bacterial in nature. Two of the main uses for polysporin eye drops are in the treatment of pink eye (bacterial conjunctivitis) and styes in which the sebaceous glands in the eyelids become infected.

The drug is used to kill the bacteria that is causing an infection. Polysporin is highly effective and usually give quick relief of the symptoms of eye infection.  The infection itself is usually cleared up in a matter of days.

Polysporin eye drops should only be used under the care of a doctor.  The drops should not be shared with others. While the drugs work quickly, it should be noted that the infection is still contagious while during treatment.

This medication should not be used by anyone who is allergic to either of the two active ingredients, polymyxin B or bacitracin.  A full course of treatment is necessary to kill the infection, so this drug should be administered as directed on the label even if the symptoms have cleared up.

Side effects of this drug are rare, but there have been reports of allergic reaction. If you experience a rash, difficultly breathing or respiratory swelling, discontinue use of this product and seek help immediately from a health care professional.

When using this medicine, care must be taken to avoid touching the tip of the applicator to any surface including the eye or hand as it can become contaminated. Although Polysporin comes in different preparations, only those forms designed specifically for ophthalmic use should be administered in the eye.

While there is no evidence that using Polysporin is harmful to pregnancy, anyone who is, or suspects they may be pregnant should inform their physician before using these eye drops.
