Some products containing PHMB are used for inter-operative irrigation, pre- and post-surgery skin and mucous membrane disinfection, post-operative dressings, surgical and non-surgical wound dressings, surgical bath/hydrotherapy, chronic wounds like diabetic foot ulcer and burn wound management, routine antisepsis during minor incisions, catheterization, scopy, first aid, surface disinfection, and linen disinfection.[5] PHMB eye drops have been used as a treatment for eyes affected by Acanthamoeba keratitis.[6]

It also has an application as a swimming-pool and spa water sanitizer in place of chlorine- or bromine-based products. It is available as Baqua-Spa 3 sanitize, as Revacil Spa 3 sanitizer, and in the Leisure Time Free system.
