Polymyxin B + Neomycin 5ml

What Is Polymyxin B + Neomycin 5ml?

Polymyxin B + Neomycin 5ml is a prescription eye drop made to treat external eye infections caused by bacteria. It combines two powerful antibiotics—neomycin and polymyxin b sulfates—in one small bottle, and that combo works together to clear out the bacteria causing redness, pain, itching, discharge, or blurred vision.

Whether you’ve got conjunctivitis (that gunky, sticky eye), blepharitis (lid inflammation), or something bacterial you picked up in a dusty, sweaty, maybe-not-clean environment, neomycin polymyxin b has your back. These infections can be more than annoying—they can threaten your sight if not treated properly.

But this drop doesn't just bring relief, it goes after the root cause. And when it comes to trusted sourcing, Sanford Pharmacy is where you can get neomycin and polymyxin b sulfates eye drops delivered securely and affordably, with answers if you’ve got questions.

Drug class

Neomycin and polymyxin b belong to the antibiotic drug class, each bringing its own strength. Neomycin is an aminoglycoside—it targets and shuts down protein production inside bacterial cells, which stops them from multiplying. Polymyxin B is a polypeptide—it disrupts the outer membrane of bacteria, kind of like punching holes in their armor.

This duo hits bacteria from two sides, and that’s what makes the combination so effective. You’ll also see similar combinations in neomycin and polymyxin b sulfates and dexamethasone ophthalmic suspension and neomycin and polymyxin b sulfates and hydrocortisone otic solution, which are used in ears and eyes too, but for slightly different needs.

What Are the Benefits of Polymyxin B + Neomycin 5ml?

The number one benefit is that it treats bacterial infections of the outer eye quickly and reliably. These drops aren’t for viral or fungal issues—this is a targeted, focused treatment for bacterial problems. It reduces symptoms like swelling, redness, discharge, crustiness, and discomfort.

It’s often used when broad coverage is needed, or when one antibiotic alone might not be enough. Because neomycin polymyxin b covers a wide range of bugs, it’s a solid choice when the exact bacteria hasn’t been identified yet.

Benefits include:

When used as directed, neomycin and polymyxin b sulfates dosage delivers strong, localized action with minimal risk of systemic side effects. Sanford Pharmacy carries this drop and similar ones like neomycin and polymyxin b sulfates and dexamethasone ophthalmic ointment, all at prices that won’t leave your wallet sore.

How Does Polymyxin B + Neomycin 5ml Work?

Dual-action antibiotic combo

Each component in neomycin polymyxin b sulfates plays a specific role. Neomycin targets bacterial protein synthesis—it gets inside and messes with the machinery that builds proteins, which bacteria need to grow and survive.

Meanwhile, polymyxin b attacks the bacterial outer wall, causing leakage and breakdown. Together, this duo prevents bacteria from multiplying and helps kill off the ones already there.

Why combination therapy matters

Using both antibiotics at once means more coverage. Some bacteria are resistant to one drug but not the other. So when used together, neomycin and polymyxin b lower the chances of resistance and increase your chances of full recovery.

That’s why this mix shows up in other treatments too, like neomycin and polymyxin b sulfates and dexamethasone and neomycin and polymyxin b sulfates and hydrocortisone drops.

Onset of Action

You might feel the difference from neomycin and polymyxin b sulfates eye drops within the first 24 hours. The burning, irritation, or discharge might start easing up. But keep in mind—just because it feels better doesn’t mean the infection is gone.

Most doctors recommend using the full course, usually 5 to 7 days, even if symptoms fade early. That helps avoid relapse or partial treatment, which could lead to antibiotic resistance.

How to Use Polymyxin B + Neomycin 5ml

Steps for proper use

Wash your hands. Shake the bottle if instructed. Tilt your head back and pull down your lower eyelid to form a pocket. Squeeze one drop of neomycin and polymyxin b sulfates eye solution into the affected eye.

Blink gently, then press the inner corner of your eye for 30–60 seconds to keep the drop from draining too fast. Use exactly as your doctor prescribed. It might be every 4 hours, or 2–4 times a day, depending on the severity.

Things to avoid

Don’t touch the dropper to your eye, fingers, or anything else. If you're using contact lenses, remove them before applying and wait 15–20 minutes after the drop before putting them back in. Don’t share your eye drops with anyone, and don’t stop early just because it feels better.

Available Forms

Polymyxin B + Neomycin 5ml comes as a 5ml ophthalmic solution in a sterile dropper bottle. Similar combinations are also available with steroids—like neomycin and polymyxin b sulfates and dexamethasone ophthalmic suspension for inflammation, or neomycin and polymyxin b sulfates and hydrocortisone otic solution for ear infections. 

You’ll find these variations at Sanford Pharmacy, where you can choose between just antibiotic or combo treatments depending on your prescription. Whether you need neomycin and polymyxin b, or the steroid combo version, Sanford helps make it affordable, fast, and safe.

How This Product Differs From Others

A lot of eye drops are either antibiotic or anti-inflammatory—not both. Neomycin and polymyxin b sulfates can be used alone or combined with other agents (like dexamethasone) depending on the infection. It’s a flexible combo with a wide bacterial kill zone, making it more useful in cases where the exact bug isn’t known.

 Also, many drops treat only mild surface infections. But neomycin and polymyxin b sulfates eye drops have deeper reach and stronger bacteria-fighting properties.

If you're comparing treatments, neomycin and polymyxin b sulfates and hydrocortisone otic solution targets the ears, while ophthalmic suspension and ointment versions focus on the eyes. Each has its place—Sanford can help you get exactly what’s written on your script.
