About this ingredient

Vancomycin hydrochloride is a glycopeptide antibiotic used to treat infections caused by gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA).[1] It works by binding to D-alanyl-D-alanine and inhibiting the polymerization of peptidoglycans in the bacterial cell wall.[1]

In compounding, vancomycin is prepared on a prescriber's order for routes and strengths that are not commercially available. For example, fortified vancomycin 5% eye drops, which are very active against MRSA, are used off-label as a topical option in the treatment of bacterial keratitis.[2]

Systemic vancomycin is used for serious gram-positive infections, including endocarditis, osteomyelitis, and skin and soft tissue infections, and oral vancomycin is used for Clostridioides difficile-associated diarrhea.[1]

Prescribers should be aware of the potential for nephrotoxicity, including acute kidney injury, and for transient or permanent ototoxicity, which can present as hearing loss, tinnitus, or vertigo.[1] Therapeutic drug monitoring with serum trough concentrations, or AUC monitoring for serious infections, is recommended.[1] Intravitreal vancomycin has been associated with hemorrhagic occlusive retinal vasculitis causing permanent vision loss.[1]

Common questions

Frequently asked questions

What are fortified vancomycin eye drops used for?

They are used under an eye specialist's care to treat serious bacterial eye infections, such as a corneal ulcer (bacterial keratitis), especially those caused by gram-positive bacteria like MRSA. They are used off-label, and a valid prescription is required.

Is there an FDA-approved vancomycin eye drop?

No. There is no FDA-approved vancomycin eye drop in the United States. When an ophthalmologist needs vancomycin's gram-positive and MRSA coverage on the eye, it must be compounded sterile to their prescription and used off-label. Compounded preparations are not FDA-approved.
