Once the methylphenidate patch is removed after 9 hours of wear time, methylphenidate plasma concentrations decline in a biexponential manner most likely due to distribution of methylphenidate from the skin after patch removal. If a patch was removed without the caregiver's knowledge, or if a patch is missing from the tray, the caregiver should be encouraged to ask the child when and how the patch was removed.Avoid exposing the application site to hair dryers, heating pads, electric blankets, heated water beds, or other direct external heat sources.
