What Are Polymyxin B Sulfate and Trimethoprim?
Polymyxin B sulfate and trimethoprim are two active ingredients in one eye drop. They work together to fight bacterial eye infections.
Polymyxin B sulfate breaks down bacteria cell walls. This causes the bacteria to burst and die.
Trimethoprim stops bacteria from making an enzyme they need to live. Without this enzyme, the bacteria can’t grow or survive.
Together, these antibiotics fight many types of eye infections. They can treat problems like pink eye and eyelid infections.
The two drugs work better together, making them a good choice for treating bacterial eye issues.

Polymyxin B sulfate and trimethoprim eye drops treat many external eye infections. They work well for bacterial conjunctivitis, which causes red, swollen, and itchy eyes.
These drops also help with corneal  and other external eye infections, which can cause pain and blurry vision.
The eye drops target bacteria to ease discomfort and help healing. They are helpful for many eye problems.
These drops provide relief by treating the infection’s cause and supporting the eye’s natural healing process.
