What Is Polymyxin B Trimethoprim?
Polymyxin B Trimethoprim (brand name Polytrim, available as a generic ophthalmic solution) is a prescription antibiotic eye drop used to manage bacterial conjunctivitis and other superficial bacterial infections of the eye. It works by combining two complementary mechanisms: polymyxin B disrupts bacterial cell membranes while trimethoprim inhibits bacterial folate synthesis, together providing broad coverage against common ocular pathogens. With the right dose and ongoing monitoring, most patients experience significant improvement within a few days of starting treatment.

Is Online Polymyxin B Trimethoprim Treatment Right for You?
Polymyxin B Trimethoprim eye drops are prescribed for adults with bacterial conjunctivitis or other superficial bacterial eye infections who have previously been evaluated by a physician. A refill is appropriate when your diagnosis is established, symptoms are consistent with prior episodes, and there are no signs of a more serious or complicated eye condition requiring in-person examination.
Because eye infections can sometimes reflect underlying conditions affecting immunity or systemic health, our licensed physicians will review your ocular and medical history before approving a refill. Patients 18 and older in any U.S. state are eligible to request a refill through Doctronic.

Frequently asked questions
Polymyxin B Trimethoprim ophthalmic solution is used to treat bacterial conjunctivitis (pink eye) and other superficial bacterial infections of the eye. It is not effective against viral or allergic conjunctivitis.
The typical dosing is one to two drops in the affected eye every three hours, up to six times daily, for seven to ten days or as directed by your physician. Tilt your head back, pull down the lower eyelid, and instill the drops without letting the tip touch your eye or any surface to avoid contamination.
No. This medication targets bacteria only. Viral conjunctivitis, which is the most common form, does not respond to antibiotic eye drops. A physician can help determine whether your infection is bacterial or viral based on your symptoms and history.
Common side effects include brief stinging or burning upon instillation, local irritation, redness, and itching. If you notice increased eye pain, vision changes, significant swelling, or signs of an allergic reaction such as rash or severe itching, contact a physician promptly.
You should avoid wearing contact lenses while you have an active eye infection and while using Polymyxin B Trimethoprim eye drops. The preservative in the solution can be absorbed by soft contact lenses and may cause irritation. Ask your physician when it is safe to resume lens wear.
Many patients notice improvement in symptoms such as discharge and redness within 24 to 48 hours of starting treatment. Complete the full prescribed course even if symptoms resolve early to reduce the risk of recurrence or antibiotic resistance.
