This article introduces the highest absorbency guides, expressed as numbers of voids, for retail pads. Long-wear pads may reduce the frequency of changes and ease the burden of care. However, there are risks of skin problems and discomfort. Discuss their use with a healthcare or care professional. Because long-wear pads are highly absorbent, avoid layering other pads over them.

Some manufacturers also sell pads for hospitals and care facilities with higher absorbency than their retail products. Highly absorbent incontinence insert pads may be available at drugstores; ask a store assistant. Discuss carefully with the wearer, family and healthcare or care professionals how many overnight changes to make, or whether to use a long-wear pad.
