Bacitracin Zinc + Polymyxin B Sulfate: Brands, Price & Uses in Bangladesh

Bacitracin Zinc + Polymyxin B Sulfate is a fixed-dose combination topical antibacterial used mainly for the prevention and treatment of minor superficial infections. Its use can be classified by strength of evidence as follows:

Established / approved uses

• Prevention of infection in minor cuts, scrapes, and minor thermal burns (first-aid use on intact or minimally broken skin).
• Treatment of minor superficial bacterial skin infections caused by susceptible organisms, primarily Staphylococcus aureus and Streptococcus pyogenes (bacitracin component) together with susceptible gram-negative organisms such as Pseudomonas aeruginosa and other Enterobacteriaceae (polymyxin B component).
• Ophthalmic ointment formulations of Bacitracin Zinc + Polymyxin B Sulfate are indicated for superficial infections of the eye and its adnexa (e.g., blepharitis, blepharoconjunctivitis, and bacterial conjunctivitis) caused by susceptible organisms, when prescribed by a physician.

Adjunct / supportive use

• As an adjunct to routine minor wound care (cleaning and dressing) to reduce the risk of secondary bacterial infection; it does not replace proper wound cleansing.

Off-label / non-approved use

• Otic (ear) use is sometimes practiced off-label in some regions for minor external ear infections, but Bacitracin Zinc + Polymyxin B Sulfate is not FDA-approved for this route and should only be used in the ear on specific medical advice.

Bacitracin Zinc + Polymyxin B Sulfate is not adequate as sole therapy for deep, puncture, or seriously contaminated wounds, animal bites, or serious burns, which require medical evaluation.

Topical skin use (ointment)

Ophthalmic use (ointment, prescription only)

Administration notes: For topical skin use, clean the affected area gently before application. For ophthalmic use, avoid letting the tip of the tube touch the eye or any surface to prevent contamination. Bacitracin Zinc + Polymyxin B Sulfate for skin use should not be applied in or near the eyes unless the specific ophthalmic formulation is prescribed for that purpose. Do not use for longer than 7 days (topical skin) unless directed by a physician, and seek medical attention if the condition worsens or fails to improve. Take/use Bacitracin Zinc + Polymyxin B Sulfate exactly as prescribed by your physician; do not stop, extend, skip applications, or share this medicine with others without medical advice.

Bacitracin Zinc + Polymyxin B Sulfate is generally well tolerated when used as directed, since systemic absorption from topical use is minimal. Reported adverse effects include:

• Common (local): mild itching, burning, stinging, or redness at the application site.
• Less common: allergic contact dermatitis or skin rash from sensitization to bacitracin or polymyxin B, which may worsen with repeated or prolonged use.
• Rare but serious: severe allergic reactions, including anaphylaxis, have been reported rarely with topical bacitracin-containing products; discontinue immediately and seek emergency medical care if signs of a severe allergic reaction (swelling of the face/throat, difficulty breathing, hives) occur.
• Ophthalmic use: transient burning, stinging, itching, or blurred vision immediately after application.

If irritation, rash, or worsening of the condition occurs, stop using Bacitracin Zinc + Polymyxin B Sulfate and consult a physician.
