Neomycin Bacitracin Zn Polymyx — Compare Prices at US & Canada Pharmacies

• Mupirocin cream is a prescription topical antibiotic medication designed to treat bacterial skin infections, particularly secondarily infected wounds caused by susceptible bacteria.
• The standard application is a thin layer applied three times daily for 10 days to the affected area, with care taken to avoid the eyes, nose, mouth, and other sensitive tissues.
• Generic mupirocin cream typically costs around $268 per 15-gram tube at retail price without insurance, though actual out-of-pocket expenses vary based on pharmacy, insurance plan, and available discounts.

Bacterial skin infections often require targeted treatment, which may be available through prescription or over-the-counter options. Mupirocin, a topical antibiotic available by prescription, treats certain bacterial skin conditions. The medication is formulated as either a cream or ointment preparation.

Mupirocin cream is a prescription-strength topical antibiotic typically supplied in a 2% formulation for direct application to skin. Generic mupirocin cream remains available through pharmacies despite the discontinuation of the brand-name Bactroban cream. The medication also comes as an ointment form. While cream is generally used for infected skin injuries, the ointment formulation is more commonly prescribed for conditions like impetigo. Unlike some topical antibiotics, mupirocin is not sold without a prescription and cannot be purchased over the counter.

The U.S. Food and Drug Administration approved mupirocin cream specifically for treating secondarily infected traumatic skin lesions—including minor cuts, scrapes, and sores—that are caused by susceptible strains of Staphylococcus aureus and Streptococcus pyogenes. The ointment formulation, rather than the cream, carries FDA approval for impetigo caused by these same bacterial species.

The choice between cream and ointment depends on the type of infection and the location being treated. Elizabeth Rubin, MD, notes, "The ointment is generally more occlusive. Consequently, it tends to be used preferentially for lesions that are dry or crusty. Conversely, the cream is easier to spread, making it preferable for application to larger or more wet areas of skin."

In clinical practice, mupirocin is frequently used to treat methicillin-resistant Staphylococcus aureus (MRSA) infections, particularly impetigo cases. Research shows that mupirocin successfully controls symptoms in over 85% of impetigo cases, including infections involving MRSA strains.

The ointment may be prescribed off-label for nasal MRSA decolonization, though mupirocin cream should never be applied inside the nasal passages. Researchers have also explored off-label applications such as infections associated with ear tubes. However, mupirocin is not appropriate for all skin infections, making professional evaluation and appropriate prescribing essential.

Follow your healthcare provider's directions precisely when using mupirocin cream. Standard instructions include:

Wash hands thoroughly before application. Use a sterile cotton swab or gauze pad to apply a small amount directly to the affected skin. Apply mupirocin cream three times daily for 10 days, or as otherwise directed by your provider. Cover the treated area with clean gauze as needed, unless your provider instructs otherwise. Wash hands after application.

Apply mupirocin cream only to the affected skin area. The medication is for external use only and must not contact the eyes, nose, mouth, or vaginal area.

Mike Daniels, DPM, president and chief medical officer at WeTreatFeet Podiatry in Baltimore, Maryland, says, "Patients always need to wash their hands before and after applying it. I tell patients this repeatedly because they forget."

Dr. Rubin cautions that overuse of mupirocin should be prevented, as should applying it to extensive skin areas without physician guidance, since both practices may increase irritation risk or promote resistant bacterial strains.

Apply a small quantity of mupirocin cream—approximately 0.5 grams or enough to coat the affected area in a thin layer. Depending on the size of the infection, this typically measures about a pea or fingertip-sized portion. Dr. Daniels explains, "More is not better. I've had patients slather it on thinking it'll work faster, and it doesn't; you just waste the tube."

Use a clean cotton swab or gauze pad to apply the medication rather than your fingers. Avoid applying additional lotions, creams, or ointments to the area unless your healthcare provider approves it.

Mupirocin cream is typically used three times daily for 10 days. Complete the entire course even if skin appearance improves sooner, because premature discontinuation may allow the infection to persist and contribute to antibiotic resistance. Dr. Daniels advises, "Finish the full course even if it looks better in a couple of days. Stopping early is how resistance builds, and trust me, mupirocin-resistant staph is a real problem now."

Do not use mupirocin beyond the prescribed duration. If symptoms do not improve after three to five days or worsen at any point, contact your healthcare provider.

Although not universal, mupirocin cream may cause side effects. More common, though still infrequent, reactions include:

Headache, burning, stinging, itching, and rash at the application site, nausea, mouth ulcers, abdominal pain, hives, and dry skin.

Severe but less common side effects include serious allergic reactions (hives, breathing difficulty, facial or throat swelling), secondary infections, and Clostridium difficile (C. difficile)–associated diarrhea. Stop using the medication and seek immediate medical attention if you experience breathing trouble, swelling, severe diarrhea, or signs that infection is worsening.

Dr. Rubin advises, "If redness, swelling, pain, or discharge increases, they should visit their physician. A fever or an acute spreading wound would indicate an immediate need to assess whether oral antibiotics or alternative diagnoses exist."

Even mild side effects warrant discussion with a healthcare provider for appropriate monitoring or evaluation.

Use mupirocin cream only as prescribed. Like all antibiotics, prolonged or inappropriate use may lead to overgrowth of resistant bacteria, fungi, or other microorganisms unresponsive to mupirocin, potentially resulting in a new infection.

Notify your healthcare provider if you are pregnant, planning pregnancy, or breastfeeding before using mupirocin cream. Although topical mupirocin is not expected to absorb significantly into the bloodstream, limited safety data exists for pregnant and nursing individuals. If mupirocin cream is applied to the nipple area during breastfeeding, it should be washed off before nursing.

Patients with kidney disease should consult their healthcare provider about mupirocin appropriateness. Although minimal amounts are expected to enter circulation, the kidneys eliminate mupirocin from the body.

Discuss any concerns about your health, skin infection, or mupirocin safety with your healthcare provider.

Yes, in certain situations. Over-the-counter alternatives include bacitracin (a single-ingredient antibiotic product), Polysporin (bacitracin and polymyxin B), and Neosporin, also known as triple antibiotic ointment (neomycin, bacitracin, and polymyxin B).

Dr. Daniels notes, "There aren't perfect over-the-counter substitutes for mupirocin because it's prescription-strength and covers MRSA (which most OTC products don't)." These nonprescription products work reasonably well for minor wounds to prevent infection but lack proven effectiveness equivalent to mupirocin for treating active bacterial infections such as impetigo or MRSA skin disease.

OTC topical antibiotics vary in composition. Bacitracin consists of a single agent, while Neosporin contains three. Products with neomycin carry increased risk of contact allergy, which may cause redness, itching, or blistering at the application site. A systematic review documented contact allergy to neomycin in approximately 3% of adults and 4% of children.

If an OTC product is being used and the infection spreads, worsens, or shows no improvement, consult your healthcare provider. They can evaluate for secondary complications and recommend appropriate treatment. Dr. Daniels advises, "If there's real infection (pus, spreading redness, warmth), skip the OTC stuff and see a provider."

Mupirocin cream pricing varies considerably based on pharmacy location, insurance coverage, and available discount programs. The average retail price without insurance is approximately $268 per 15-gram tube of 2% cream. Actual cost can be significantly lower depending on your insurance plan, pharmacy choice, and whether discount cards or manufacturer coupons are available. Comparing prices across local pharmacies or using online price-comparison tools may help identify more affordable options.

Chad Shaffer, MD, notes that "Mupirocin cream costs about four times as much as mupirocin ointment, so we do not prescribe it much, but it may be preferable in some situations when it is easier to apply."

Mupirocin typically shows effectiveness within three to five days of consistent use. If you observe no improvement during this period or if symptoms worsen, contact your healthcare provider.

Yes, mupirocin is a topical antibiotic belonging to the pseudomonic acid class, chemically distinct from other standard antibiotic families.

No, mupirocin is not available without a prescription in the United States. A prescription from a healthcare provider is required to obtain mupirocin.

Mupirocin cream may be used on minor open wounds, such as cuts or scrapes, when they have secondary bacterial infections. Always consult your healthcare provider before using mupirocin to ensure it is appropriate for your specific wound.
