Wound filler is designed to maintain moisture within a wound and help manage fluid drainage. These products are considered a secondary dressing. Typically, they are used to treat wounds that are infected, wounds that are draining, or deep wounds that require packing as they heal. There are many different types of wound filler available. Gels such as SoloSite Gel are a common option. Hydrophilic powder fillers like the Multidex powder wound filler are another option. You’ll also find creams, foams, ointments, pads, beads, and other types of wound fillers depending on your needs.
