📖 Dexamethasone / Neomycin / Polymyxin B: Patient Information Guide
A plain-language walkthrough of Dexamethasone / Neomycin / Polymyxin B — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.
🎯What it's used for▾
This combination of dexamethasone (a steroid), neomycin, and polymyxin B (two antibiotics) is used in the eye for inflammatory conditions where bacterial infection is also a concern. Supported uses across the available products include:
- Inflammation of the conjunctiva (tissue lining the eyelid and eye surface), cornea (clear front of the eye), and the anterior segment (front chamber) of the eye
- Infective conjunctivitis (eye infections with inflammation) where the benefits of steroid use outweigh the risks
- Chronic anterior uveitis (long-term inflammation inside the front part of the eye)
- Corneal injury from chemical burns, radiation burns, or heat burns
- Eye injury from penetration of a foreign body
- Situations where bacterial infection risk is high or large numbers of bacteria are expected to be present in the eye
⚙️How it works▾
Dexamethasone is a corticosteroid that suppresses the inflammatory response in the eye — it dials down redness, swelling, and irritation. Neomycin and polymyxin B are antibiotics that target and kill common bacteria that can infect the eye, including Staphylococcus aureus, Pseudomonas aeruginosa, and several others. Combining all three in one product ensures you get both the anti-inflammatory and the antibacterial effects together, with consistent dosing.
Note that this product does not cover all bacteria — it is not effective against Serratia marcescens or streptococci (including Streptococcus pneumoniae), so it may not be the right choice for infections caused by those organisms.
💊How it's taken▾
This medication comes as eye drops (suspension) and eye ointment — both for use in the eye only. Eye drops are instilled directly; the number of times per day depends on how severe the inflammation is, and your doctor will adjust the frequency as your eye improves. The ointment is applied inside the lower eyelid up to three or four times daily; Neomycin and Polymyxin B Sulfates and Dexamethasone Ophthalmic Ointment may also be used at bedtime alongside the eye drop form.
- Eye drops: shake well before each use
- Do not touch the dropper tip or ointment tube tip to your eye
- Follow your prescriber's exact schedule — do not stop early or refill without re-evaluation
🤒Side effects — in detail▾
Side effects can come from the steroid, the antibiotic, or both components combined. Common reactions include:
- Allergic eye sensitivity or irritation (most often from neomycin)
- Elevated eye pressure, which can lead to glaucoma with long-term use
- Posterior subcapsular cataract (a type of clouding at the back of the eye's lens) with prolonged use
- Delayed wound or corneal healing
- Keratitis (corneal inflammation), conjunctivitis, or corneal ulcers
- Conjunctival hyperemia (eye redness)
- Secondary bacterial or fungal eye infections
- Headache
Serious reactions — including Stevens-Johnson syndrome (severe blistering of the skin and mucous membranes) and anaphylaxis (severe whole-body allergic reaction) — have been reported rarely. Stop using and get medical help right away if you notice worsening symptoms, a rash, or difficulty breathing.
⚠️Warnings & precautions▾
- Do not use for viral eye infections — steroids can make herpes simplex, chickenpox, and other viral eye infections significantly worse. If you have a history of herpes simplex eye disease, your doctor will need to monitor you closely.
- Prolonged use raises eye pressure — long-term steroid use in the eye can cause glaucoma (optic nerve damage) and cataracts. Eye pressure should be checked regularly if you use this for 10 days or more.
- Risk of corneal thinning and perforation — steroids can thin the cornea or the white of the eye over time; this is more dangerous in people who already have thin tissue.
- New infections can develop — by suppressing local immunity, the steroid can allow fungal or secondary bacterial infections to take hold. Any persistent eye sore or ulcer should be evaluated promptly.
- Allergic reactions to neomycin — can range from local irritation to serious systemic (whole-body) reactions. People sensitive to neomycin may also react to other aminoglycoside antibiotics.
- Steroid absorption in high doses — if used in excess of the recommended dose, especially in children or people taking certain other medications, enough dexamethasone may be absorbed to cause Cushing's syndrome or adrenal suppression.
🔀What it interacts with▾
The FDA label identifies one key drug interaction category to be aware of:
- CYP3A4 inhibitors — drugs that slow the breakdown of dexamethasone in the body (such as certain antifungal medications, some antibiotics, and some HIV medications) can raise dexamethasone levels and increase the risk of steroid side effects like adrenal suppression or Cushing's syndrome, particularly in children and predisposed patients.
This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.
📋Before taking it▾
- Do not use if you have a viral eye infection — including herpes simplex keratitis (dendritic keratitis), chickenpox (varicella), or vaccinia
- Do not use if you have a fungal infection of the eye or a mycobacterial eye infection
- Tell your doctor if you have ever had a herpes simplex eye infection — careful monitoring is required
- Tell your doctor if you have glaucoma or high eye pressure — steroids can raise it further
- Tell your doctor if you have had recent eye surgery — steroid use afterward may slow healing
- Tell your doctor if you are allergic to neomycin or any other aminoglycoside antibiotic — cross-sensitivity can occur
- Tell your doctor about all medications you take, especially CYP3A4 inhibitors (such as certain antifungals or HIV drugs)
- Use with caution in children — monitoring eye pressure may be difficult, and systemic steroid effects can occur
- Do not use if you are allergic to any ingredient in the product
📡Pharmacodynamics — effects in the body▾
The corticosteroid component (dexamethasone) measurably reduces inflammation in the eye — decreasing swelling, redness, and tissue irritation. However, it also partially suppresses the eye's immune defenses, which can slow healing and create an opening for secondary infections. The potency of the corticosteroid effect depends on its concentration and how it is released from the formulation.
📦How to store it▾
Store between 15°-25° C (59°-77° F). Store upright. KEEP OUT OF REACH OF CHILDREN.

📈 What people report — real-world data (FDA FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Dexamethasone / Neomycin / Polymyxin B — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Dexamethasone / Neomycin / Polymyxin B in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

How we combine label and product data
HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 25 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.
For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Harrow Eye, LLC is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
