A packaged intermittent urinary catheter comprising a single use catheter, a packaging surrounding the catheter, and a fluid reservoir holding a lubricant which, upon rupturing the fluid reservoir, is transferred into the packaging to immerse at least a portion of the catheter in the lubricant to prepare the catheter for use, wherein the lubricant comprises an antimicrobial medium. The invention further provides a method of using a packaged intermittent urinary catheter, and the use of a medium comprising at least one species independently chosen from: hypochlorous acid, at least one hypochlorite salt, chlorine dioxide, at least one chlorhexidine salt, and combinations thereof, as an antimicrobial medium for a single use intermittent urinary catheter.

The use of PREVORA brand topical dental solution (100 mg / ml chlorhexidine) sold by CHX Technologies, Inc., Toronto, Canada, to treat and / or prevent the advance of both dental decay (caries) and periodontal disease in a simplified method of application in a non-clinical setting. A rapid and simplified treatment with PREVORA comprising the application of PREVORA with a cotton swab, for example, on the surface of the tooth extending down to the gum line was found to produce dramatic reduction in soft tissue inflammation. No cleaning, scaling, or other procedures were required to obtain this effect. Thus, no special equipment or skill is required to administer a PREVORA treatment. This enables a dental professional, medical assistant, nurse, pharmacist, for example, to treat the elderly or disabled where they live. Moreover, the typical chair time for such treatment is 10-15 minutes, or less, and the procedure is pain-free.
