How often should I change an adult diaper?

Most adults should change their diaper every 4–6 hours, but it also depends on the level of incontinence and the type of diaper being used. Overnight diapers are made to last longer, sometimes up to 8–10 hours, for uninterrupted sleep. Regularly changing your diaper helps prevent leaks, odor, and skin irritation, especially if you have sensitive skin or use them daily.
